3n-15=7n+n EXPLAIN NUMBER FORM NO WORDS AT ALL
Step-by-step explanation:
3n-7n-n = 15
5n = 15
n = 15 ÷ 5
n = 3
Step-by-step explanation:
3n−15=7n+n
3n-15=8n
3n-15+15=8n+15
3n=8n+15
3n-8n=8n+15-8n
-5n=15
answer:
n= -3

One person can complete a typing project in 6 hours, and another can complete the same project in 9 hours. How long will it take the two people working together to complete the project?
Answer:
3.6 hours
Step-by-step explanation:
One person can complete a typing project in 6 hours,
Hence, in 1 hour, 1/6 of the project is completed by person A
Another can complete the same project in 9 hours.
Hence, in 1 hour, 1/9 of the project is completed by person B
Let the number of hours of completing the project be represented by 1
Hence,
x/6 + x/9 = 1
We find the L.C.M
9x + 6x/54= 1
15x/54 = 1
Cross Multiply
15x = 54
x = 54/15
x = 3.6 hours.
Therefore, both people can complete the project in 3.6 hours.

Solve for Y: when X = 6
y = -3x +2
Answer:
Y=-16
Step-by-step explanation:
-3(6)+3
-18+2
y=-16
Answer:
-16
Step-by-step explanation:
We can evaluate y = -3x + 2 for x = 6. Substituting 6 for x in y = -3x +2, we get:
y = -3(6) + 2 = -18 + 2 = -16
The equation y = -3x + 2 has already been "solved" for y. At this point you are evaluating this equation at x = 6.
Convert the distance John lives from school to home from miles to inches. Assume John lives 5.2
miles from school. Remember 1 mile = 5280 ft
Answer:
329472 inches

Find the solution set for this inequality, -2x + 4 > -4x + 8
Answer:
The answer is
x > 2Step-by-step explanation:
- 2x + 4 > - 4x + 8
Add 4x to both sides of the inequality
That's
- 2x + 4x + 4 > - 4x + 4x + 8
2x + 4 > 8
Subtract 4 from both sides
That's
2x + 4 - 4 > 8 - 4
2x > 4
Divide both sides by 2
That's
[tex] \frac{2x}{2} > \frac{4}{2} [/tex]
We have the final answer as
x > 2Hope this helps you
Which is the better buy? 3-yard roll of butcher paper for $2.88 OR 18-ft roll of butcher paper for $11.52
Answer:
18-ft.
Step-by-step explanation:
WHEW. Just buy it for 11.52. If you bought 18 yd of butcher paper from the 3 yd roll you would be spending almost 52 dollars!
Answer: 3-Yard roll or butcher paper
Step-by-step explanation:
3 Yards = 9 Feet. 3 yards is half of 18 feet. And the cost of 3 yards is only 2.88, And since it is half of the amount of 18 feet, we multiply by two. ($5.76). Meaning 3 Yards is better to buy.
Point B splits a segment AC with ratio AB:BC=2:1. Point D splits a segment AB with the ratio AD:DB=3:2. What is the ratio for AD:DC?
Answer:
The ratio for AD:DC is 2:3
Step-by-step explanation:
The given information are;
The ratio by which point B splits AC as AB:BC = 2:1
The ratio by which point D splits AB as AD:DB = 3:2
Therefore, we have;
The fraction of AC that is equal to AB is given as follows;
AB = 2/(2 + 1) × AC = 2/3 × AC
AB = 2/3 × AC
Similarly
BC = 1/3 × AC
Also the fraction of AB that is equal to AD is given as follows;
AD = 3/(3 + 2) × AB = 3/5 × AB
AD = 3/5 × AB
Therefore, the fraction of AC that is equal to AD is given as follows;
AD = 3/5 × AB = 3/5 × 2/3 × AC = 2/5 × AC
Therefore, DC = (1 - 2/5) × AC = 3/5 × AC
Which gives the ration of AD to DC or AD:DC as being;
AD:DC = 2/5 × AC : 3/5 × AC = 2/5:3/5 = 2:3
The ratio for AD:DC = 2:3.
simplify
x3-9x
divided by
x3+x2-6x
Step-by-step explanation:
(x^3 - 9x) divided by (x^3 + x^2 - 6x)
= x(x^2 - 9) divided by x(x^2 + x - 6)
= x(x + 3)(x - 3) divided by x(x - 2)(x + 3)
= (x - 3)/(x - 2).

if a fraction converts into a decimal that eventually stops what do you call it ??
Answer:
Terminating decimal.
Step-by-step explanation:
We need to find, if a fraction converts into a decimal that eventually stops what do we call it.
If a fraction converts into a decimal that eventually stops is called terminating decimals.
For example : 0.1, 2.45, 3.4657 etc.
If a fraction converts into a decimal that is repeating and do not stops is called non-terminating recurring decimals.
For example : 0.333..., 2.3454545... etc.
If a fraction converts into a decimal that is not repeating and do not stops is called non-terminating, non-recurring decimals.
For example : 0.2345172..., 2.34093795... etc.
Therefore, required answer is terminating decimal.
how do i find the hypotenuse using the pythagorean theorem
Step-by-step explanation:
You multiply the two other sides by itself like 12x12=144 and do that for all the sides that you know then you add up all of the numbers you got from adding like 144 plus 64 equals 208 and then 208 is the hypotenuse.
Subtract 1 + ( - 1 ) - ( - 3 ). Hint: Add the first two numbers, then subtract the -3 from the result of that addition

Eduardo solved the following inequality, and his work is shown below: −5(x + 4) + 21 ≥ −3 + 4(x − 8) −5x − 20 + 21 ≥ −3 + 4x − 32 −5x + 1 ≥ 4x − 35 −9x ≥ −36 x ≥ 4 What mistake did Eduardo make in solving the inequality? (2 points)
Answer:
the comparison was not reversed when dividing by -9
Step-by-step explanation:
It looks like Eduardo's steps might be ...
−5(x + 4) + 21 ≥ −3 + 4(x − 8)
−5x − 20 + 21 ≥ −3 + 4x − 32 . . . . correct
−5x + 1 ≥ 4x − 35 . . . . correct
−9x ≥ −36 . . . . correct
x ≥ 4 . . . . . should be x ≤ 4
Dividing by -9 should reverse the comparison symbol.
Answer:
should be x ≤ 4

Point G is on line segment FH. Given FH = 19 and FG = 12,
determine the length GH.
Answer:
7
Step-by-step explanation:
Let’s think about this like a number line.
If we have a number line with the ends of F and H, and G is somewhere in between, it would look something like this.
F———-G———H
We know that FH = 19 and that FG is 12.
This means that GH will be the FH - FG
[tex]19 - 12 = 7[/tex]
So FG is 7.
Hope this helped!
