Answer:
r=4
Step-by-step explanation:
Let's solve your equation step-by-step.
−4(r+2)=4(2−2r)
Step 1: Simplify both sides of the equation.
−4(r+2)=4(2−2r)
(−4)(r)+(−4)(2)=(4)(2)+(4)(−2r)(Distribute)
−4r+−8=8+−8r
−4r−8=−8r+8
Step 2: Add 8r to both sides.
−4r−8+8r=−8r+8+8r
4r−8=8
Step 3: Add 8 to both sides.
4r−8+8=8+8
4r=16
Step 4: Divide both sides by 4.
4r
4
=
16

Answer:
r=4
Answer:
10.99%.
Step-by-step explanation:
We have been given that the Smiths bought new furniture that cost $3,298.00. The store offered them an option of putting $600 down and making equal payments of $300 a month for 10 months.
First of all, we will find amount paid by down-payments in 10 months.
Total amount paid by Smiths: 
.
Now we will find amount paid in interest by subtracting initial amount from total amount.
10 months = 10/12 year =5/6 year.
Now, we will use simple interest formula to solve for interest rate.
Therefore, the annual interest rate is 10.99%.
Answer:
the anser is B. btw you should try the website Desmos. Its a graph calculater
Step-by-step explanation:
The answer to your question is $231
Perimeter of square : p = 4a.....
p = 4(x + 2)
p = 4x + 8
perimeter of rectangle : p = 2(L + W)
p = 2(3x + 2 + x - 1)
p = 2(4x + 1)
p = 8x + 2
so if the perimeters are te same, lets set them equal to each other and solve for x
4x + 8 = 8x + 2
8 - 2 = 8x - 4x
6 = 4x
6/4 = x
1.5 = x
the square : p = 4x + 8.....p = 4(1.5) + 8.....p = 14 meters
the rectangle : p = 8x + 2....p = 8(1.5) + 2.....p = 14 meters
so she bought 14 meters of fencing <==
