Answer:

x=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

7x−2(x−10)=40

7x+(−2)(x)+(−2)(−10)=40(Distribute)

7x+−2x+20=40

(7x+−2x)+(20)=40(Combine Like Terms)

5x+20=40

5x+20=40

Step 2: Subtract 20 from both sides.

5x+20−20=40−20

5x=20

Step 3: Divide both sides by 5.

5 divided by 20 = 4

5 divided by 5 =1

x=4

Ann and Tom want to establish a fund for their​ grandson's college education. What lump sum must they deposit at an 8.2​% annual
GaryK [48]
Compound interest formula = a=P(1+r/n)^nt

P= lump sum to deposit (solving for)

A= amount accumulated over the entire time (20000)

n= number of times interest is compounded annually (1)

r= rate of interest (0.82)

T= total number of years (15)

20000=P(1+0.082/1)^1*15

20000=P(1.082)^15
20000=P(3.26143638)
20000/3.26143638=P
P=$6132.2674

What is the solution to the equation 2(m - 8) = 4(m + 6) ? m =
ExtremeBDS [4]
The first thing that we want to do is simplify both side of this equation. 

2(m-8).
The first thing we have to do, is multiple 2 by m and -8, also called distributing. So, when we do that, we get
2(m-8)=2*m + 2*-8 = 2m-16

4(m+6)
Now, we do the same thing we did for the first parenthesis, and that's multiple 4 by m and 6. 
4(m+6)=4*m + 4*6 = 4m+24

Now, we need to get m by itself on one side. So, lets bring the equation from the right to the left

2m-16 = 4m + 24     (bring 4m to the other side by subtracting)
2m-16-4m = 24        (bring -16 to the right by adding)
-2m=24+16
-2m=40                    (divide both sides by -2 to get your value for m)
m=40/-2 = -20

So, our answer is m = -20

Once a large pink​ ribbon, the sign of the fight against breast​ cancer, was erected out of pink​ post-it notes on a billboard.
igomit [66]

Answer:

60 feet

Step-by-step explanation:

The shape of a billboard = Rectangle

Area of a rectangle = Length(Height) × Width

Area = 3420 square feet

Width = 57 feet

Height = Area of the billboard/Width

Height = 3420 ft²/57 ft

Height = 60 feet

Therefore, the height of the billboard is 60 feet
