You need to divide 313.5/12.5=25.08 so the width is 25.08 feet
Answer and Step-by-step explanation:
For these system of equations, it would be easier to use the substitution method, as we are have one equation that is being equaled to a variable.
Plug the second equation into the value of b for the first equation.
5a + 3(-2a + 3) = 11
Distribute the 3.
5a - 6a + 3 = 11
Simplify.
-a + 3 = 11
Subtract 3 from both sides of the equation.
-a = 8
Divide both sides by -1.
a = -8
Now, we can plug this value into the second equation.
-2(-8) + 3 = b
Multiply -2 and -8 together.
16 + 3 = b
Add together 16 and 3.
19 = b
<u>a = -8</u>
<u>b = 19</u>

Answer:
B: 375 ft^2
Step-by-step explanation:
20 x 15 + 10 x 15/2 = 375
Answer:
3 and 4
Step-by-step explanation:
Well, here's a short list of squares.
1^2=1
2^2=4
3^2=9
4^2=16
5^2=25
6^2=36
15 is between 9 and 16, so the two whole numbers closest to it is 3 and 4.
