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]

6m-6=9m+15 (Show work)​

Answers

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 = -7

I can’t figure out the answer to x/3-9=0

Answers

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

3(x+1) = 2(x-5)
Solve for x

Answers

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.

1. Frank drives from Adams to Harrison which is a distance of 310 miles. He then travels to Perryton which is 40 miles from Harrison. If it takes him 5 hours to complete the entire trip, how fast is he traveling if he is traveling at a constant rate of speed?

Answers

Answer:

70 mph

Step-by-step explanation:

The total number of miles Frank traveled is 350 miles (Adams>Harrison=310, Harrison>Perryton(10)= 350)

350 divided by 5 is 70.

Therefore he was going 70 mph.

|x-1|+5=2 also this question

Answers

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.

Find MP.

MN=17
NP=3y
MP=5y+9

Answers

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]

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.

Solve the equation, 4 - (x + 1) = 6.

x = -9
x = 3
x = -3
x = 9

Answers

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]


If the line px -5y = 60 has a slope of -23 then p equals ....

Answers

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

A line has this equation: y= -9x-2
Write an equation for the parallel line that goes through (2, -3).

Answers

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
