Answer:
D.) 1/4
Step-by-step explanation:
6/9 x 3/8
6(3) /8(9)
= 18/72
18/18=1
72/18=4
= D.) 1/4
Answer:
D. 1/4
Step-by-step explanation:
First, we will multiply the numerator 6 × 3 = 18. Then, we'll multiply the denominators, 9 × 8 = 72. Then, divide 18 ÷ 18 = 1 and 72 ÷ 18 = 4. So there we go. the numerator is 1 and the denominator is 4. So the answer is 1/4 which is a proper fraction :) (mark this answer brainliest plz )

Find MP.
MN=17
NP=3y
MP=5y+9
Answer:
[tex] MP = 29 [/tex]
Step-by-step explanation:
Given:
[tex] MN = 17 [/tex]
[tex] NP = 3y [/tex]
[tex] MP = 5y + 9 [/tex]
[tex] MN + NP = MP [/tex] (segment addition postulate)
[tex] 17 + 3y = 5y + 9 [/tex] (substitution)
[tex] 3y = 5y + 9 - 17 [/tex] (subtracting 17 from each side)
[tex] 3y = 5y + 8 [/tex]
[tex] 3y - 5y = 5y - 8 - 5y [/tex] (Subtracting 5y from both sides)
[tex] -2y = 5y - 8 - 5y [/tex]
[tex] -2y = - 8 [/tex]
[tex] y = 4 [/tex] (dividing both sides by -2)
[tex] MP = 5y + 9 [/tex]
Plug in the value of y
[tex] MP = 5(4) + 9 = 20 + 9 [/tex]
[tex] MP = 29 [/tex]
A discrete relationship is shown below between the number of workers on the job and the number of bricks
placed on the wall.
Workers
1
2
3
4
Bricks Placed
90
180
270
360
What’s the relationship
Answer:
[tex]b = 90w[/tex]
Step-by-step explanation:
Required
Determine the relationship
Represent the workers with w and bricks with b
First, we need to determine the constant of proportionality using:
[tex]b = kw[/tex]
Solve for k
[tex]k = \frac{b}{w}[/tex]
When w = 1; b = 90:
[tex]k = \frac{90}{1}[/tex]
[tex]k = 90[/tex]
When w = 2; k =180
[tex]k = \frac{180}{2}[/tex]
[tex]k = 90[/tex]
Notice that [tex]k = 90[/tex] in both cases;
Substitute 90 for k in [tex]b = kw[/tex]
[tex]b = 90w[/tex]
Hence; the relationship is [tex]b = 90w[/tex]

If 7x – 7 = -21 then 12x=____?
I can’t figure out the answer to x/3-9=0
Answer:
x = 27
Step-by-step explanation:
x/3-9=0
Add 9 to each side
x/3-9+9=0+9
x/3 = 9
Multiply each side by 3
x/3*3 = 9*3
x = 27
|x-1|+5=2 also this question
Answer:
No solution
Step-by-step explanation:
There are no values of x that make the equation true.
Answer: No solutions
==========================================
Explanation:
Start things off by subtracting 5 from both sides
|x-1|+5 = 2
|x-1|+5-5 = 2-5
|x-1| = -3
We cannot go any further after this point. The result of any absolute value is never negative. The absolute value represents distance from some number to 0. For example, saying |-7| = 7 means -7 is seven units away from 0 on a number line. Negative distance does not make sense.
So going back to |x-1| = -3 makes no sense as well. There are no numbers we can plug in for x to have |x-1| = -3 be true.
The equation |x-1| = -3 has no solutions, so the original equation doesn't have any solutions either.
Which expression is equivalent to 21 - (-5) ?
A: 21 - 5
B: -21 + 5
C: 21 + 5
D: -21 - 5
Answer:
C: 21 + 5
Step-by-step explanation:
21 - (-5)
21 + 5
Distribute the '-' into the '-5'. You would get positive 5.
Option C should be the correct answer.

A line has this equation: y= -9x-2
Write an equation for the parallel line that goes through (2, -3).
Answer:
y = - 9x + 15
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 9x - 2 ← is in slope- intercept form
with slope m = - 9
Parallel lines have equal slopes, thus
y = - 9x + c ← is the partial equation
To find c substitute (2, - 3) into the partial equation
- 3 = - 18 + c ⇒ c = - 3 + 18 = 15
y = - 9x + 15 ← equation of parallel line

A car traveled 180 kilometers in 3 hours.which stamens bets describes the distance traveled by the car per hour ?
Answer:
the car traveled 60 kph
Step-by-step explanation:
180 km / 3 hours = 60kpm
(not sure if that's how kilometers per hour is written, I am used to miles per hour.)
Solve the equation, 4 - (x + 1) = 6.
x = -9
x = 3
x = -3
x = 9
Answer:
x = -3
Step-by-step explanation:
[tex]4-(x+1) =6[/tex]
Distribute the negative
[tex]4 - x - 1 = 6[/tex]
Combine like terms on Left Hand Side
[tex]- x + 3 = 6[/tex]
Substract 3 from both sides
[tex]-x = 3[/tex]
Divide both sides by -1 to get rid of the negative
∴ [tex]x = - 3[/tex]
The sum of 16 and a number x is equal to 19
Answer:
x = 3
Step-by-step explanation:
We can write the equation as 16 + x = 19
To solve we can work backwards, I know the opposite of adding is subracting... so 19 - 16 = 3 which means x is equal to 3.
Hope that helps and have a great day!
Hey there!
ANSWER: [tex]x=3[/tex]EXPLANATION:[tex]16+x=19[/tex]
There is an easy way to solve this question. First, subtract 19 - 16.
[tex]19-16=3[/tex]
Now let's try putting 3 in x to see if it makes sense.
[tex]16+x=19\\16+3=19(ANSWER)[/tex]
It equaled 19. So this is your answer.

How to write a mixed number in science notation [tex]45\frac{3}{8}[/tex]
Answer:
[tex]4.5375*10^1[/tex]
Step-by-step explanation:
The long division for 3/8 results in getting 0.375, so 45 3/8 is 45.375.
From here, the only thing you can really do is divide it by 10 to get
4.5375 and since you can't divide further, the answer would be
4.5375 * 10^1

NEED HELP!!!
Solve each proportion.
Leave your answer as a fraction in simplest form.
Questions in pictures...
Answer:
see explanation
Step-by-step explanation:
(1)
[tex]\frac{6}{2}[/tex] = [tex]\frac{4}{p}[/tex] ( cross- multiply )
6p = 8 ( divide both sides by 6 )
p = [tex]\frac{8}{6}[/tex] = [tex]\frac{4}{3}[/tex]
(2)
[tex]\frac{n}{4}[/tex] = [tex]\frac{8}{7}[/tex] ( cross- multiply )
7n = 32 ( divide both sides by 7 )
n = [tex]\frac{32}{7}[/tex]
(3)
[tex]\frac{5}{3}[/tex] = [tex]\frac{x}{4}[/tex] ( cross- multiply )
3x = 20 ( divide both sides by 3 )
x = [tex]\frac{20}{3}[/tex]

Which equation is equivalent to I = prt?
A. P = I + rt
B. P = Irt
C. P = I - rt
D. P = I/rt
Answer: Choice D. P = i/rt
This is the same as saying P = i/(rt). The parenthesis are preferred in my opinion to indicate we have rt in the denominator and not just r.
======================================
Explanation:
In the original equation, prt is the same as p*r*t. So we multiply p, r and t to get prt.
This can be thought of as p*(rt). To isolate p, we undo the multiplication done to the variable p. We will divide both sides by rt to get
i = prt
i = p*(rt)
i/(rt) = p*(rt)/(rt) ... dividing both sides by rt
i/(rt) = p
p = i/(rt)

6m-6=9m+15 (Show work)
Answer:
[tex]m=-7[/tex]
Step-by-step explanation:
[tex]6m-6=9m+15[/tex]
Add 6 to both sides:
[tex]6m-6+6=9m+15+6[/tex]
[tex]6m=9m+21[/tex]
Subtract 9m from both sides:
[tex]6m-9m=9m+21-9m[/tex]
[tex]-3m=21[/tex]
Divide both sides by -3:
[tex]\frac{-3m}{-3}=\frac{21}{-3}[/tex]
[tex]m=-7[/tex]
Answer:
m = -7
Step-by-step explanation:
Combine like factors. It should now look like this: 6m - 9m = 6 + 156 + 15 = 21Plug 21 in: 6m - 9m = 216m - 9m = -3mPlug -3m in: -3m = 21Divide each side by -3 to cancel out the -3 next to x. It should now look like this: m = -7I hope this helps!
what is ??? 5(m-n) It’s distributive property and simply it
If the line px -5y = 60 has a slope of -23 then p equals ....
Answer:
p = - 115
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
px - 5y = 60 ( subtract px from both sides )
- 5y = - px + 60 ( divide all terms by - 5 )
y = [tex]\frac{1}{5}[/tex] px - 12 ← in slope- intercept form
with slope m = [tex]\frac{1}{5}[/tex] p , thus
[tex]\frac{1}{5}[/tex] p = - 23 ( multiply both sides by 5 to clear the fraction )
p = - 115

Answer:
1/2 im pretty sure
Step-by-step explanation:
A train traveled 10 miles in 6 minutes.
At this rate, how far will it travel in 20
minutes?
Hey there! I'm happy to help!
First, let's see how many times 6 minutes fits into 20 minutes.
20/6=3 1/3
So, we are traveling 10 miles 3 1/3 times!
10×3 1/3=33 1/3
This train will travel 33 1/3 miles in 20 minutes.

3(x+1) = 2(x-5)
Solve for x
Answer:
x = -13
Step-by-step explanation:
3(x+1) = 2(x-5)
3x + 3 = 2x - 10
3x - 2x = -10 - 3
x = -13
Answer:
x = -13
Step-by-step explanation:
To solve for x, we will have to get the equation in a form with x by itself on one side and a value on the right side.
3(x + 1) = 2(x - 5)
Distribute the 3 on the left side and the 5 on the right side.
3x + 3 = 2x - 10
Subtract 3 from both sides.
3x = 2x - 13
Subtract 2x from both sides.
x = -13
And now we have the answer of x = -13.
I hope you find my answer helpful.
