Answer:

m=  -2

Step-by-step explanation:

simplify and solve

9m-12-3m=2m-18+m

6m-12=3m-18

3m=-6

m=-2

Answer:

m=-2

Step-by-step explanation:

3(3m-4)-3m=2m-18+m

remove the parentheses and collect like terms

9m-12-3m=3m-18

collect the terms

6m-12=3m-18

move the terms

6m-3m=-18+12

collect like terms and add them

3m=-6

Divide both sides by 3

m=-2

Answer:

The answer would be y=-5/3x-5!

Step-by-step explanation:

You want to make the equation to y=mx+b, so you have to make y by its self. Subtract 5x from both sides and you'll get 3y=-5x-15. Now divide 3 by both sides and you'll get y=-5/3x-5 which would be the answer!

Answer:

y=(-5/3)x-5

Step-by-step explanation:

so the slope intersect form is y=mx+b

3y+5x=-15

subtract 5x from both sides

3y= -5x-15

divide both sides by 3

y= (-5/3)x - 5

Answer:

.25

Step-by-step explanation:

37.50/5=7.5

58/8=7.25

7.5-7.25=.25

Answer:

260

Step-by-step explanation:

So first you need to multiply 5 and 37. and the is 5×37 equals 185. So now your gonna multiply 8 by 58 and that is 464. So now that you have those two numbers ( 185, 464 ) your gonna add how ever much you need to get 464. So the closest to get to 464 is gonna be 260 I'm pretty sure.

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

The number of loaves Josh can bake with 13 and one-third cups of flour is 4 loaves.

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

Josh wants to determine the number of loaves of bread he can bake using the 13 and one-third cups of flour he has.

13(1/3) can be written as,

= 13(1/3)

= 40/3

Each loaf requires 3 and four-fifths cups of flour.

This can be written as,

3(4/5) cups of flour = 1 loaf

19/5 cups of flour = 1 loaf

Multiply 5/19 on both sides.

1 cup of flour = 5/19 loaf

Multiply 40/3 on both sides.

40/3 cups of flour = 40/3 x 5/19 loaf

40/3 cups of flour = 3.5 loaf

This means we can make 4 loaves.

Thus,

The number of loaves Josh can bake with 13 and one-third cups of flour is 4 loaves.

Answer: The point G is G(18,-9)

Step-by-step explanation:

Midpoint:

Write the formula for midpoint of the A(x_1,y_1) and B(x_2,y_2).

[(x_1+x_2)/2,(y_1+y_2)/2]

G(x,y), H(-2,9)

(x+(-2))=16

x-2 =16

x =18

(y+9)/2=0

y+9=0

y=-9

The point G is G(18,-9)

Answer:

-55.32

Step-by-step explanation:

I hope this helps!

Answer:

Well the number would have to be a negative number, because, no positive number can cause a smaller number adding a positive number will always cause a larger number.

So the answer is: $55.32+(-$55.32)

Adding the -55.32 causes it to even out meaning that u basically just added the debt of 55.32. This debt is causing an decrease in the amount of money she has. So really you are subtracting money

Answer: D 1 hour 56 minutes

Answer:

D. 1 hour 56 minutes

Step-by-step explanation:

Well, if you add 2 hours to 12:14, it would be 2:14, so you know it's less than 2 hours. B and D are the only choices that have 1 hour. So, if Aaron left at 2:10, you have to subtract 4 minutes from 2 hours. That would be 1 hour and 56 minutes Aaron spent at the mall.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Solving for x

1. 2x - 2 ≥ 0 ⇒ 2x ≥ 2 ⇒ x ≥ 1

2. 2x - 2 < 0 ⇒ 2x < 2 ⇒ x < 1

Answer:

the value of x is 23..

Step-by-step explanation:

(5x+4)+(2x+15) = 180. [being supplementary angle]

7x+19 = 180

7x = 180-19

x = 161÷7

x = 23

Answer:

1/5 as a percentage:

1/5*100

1/1*20

20/1

20%

1/5 as decimal:

(JUST SIMPLY DIVIDE 1/5)

0.2

Answer:

20% and 0.20

Step-by-step explanation:

Let's say 5/5 = 100, so then in order to convert 1/5 into a percentage, all you have to do is divide 100 by 5, and that will be your percentage:

100 / 5 = 20

So, 1/5 = 20%

Now, as a decimal its basically the same thing, but instead of thinking of it as 100, you think of it as 1.00, and then your decimal form of 1/5 will be 0.20

Hope this helps :)
