s = 6 + e
s + e = 28
We can use this system of equations to find the exact values of s and e.
We have a current value of s, so we can find the exact value of e now.
e + e + 6 = 28
<em><u>Combine like terms.</u></em>
2e + 6 = 28
<em><u>Subtract both sides by 6.</u></em>
2e = 22
<em><u>Divide both sides by 2.</u></em>
e = 11
Now we have an exact value of e, and can solve for the value of s.
s = 6 + 11
s = 17
Sophia is 17 years old, and Eric is 11 years old.
Answer:
6x+24
Step-by-step explanation:
6(3x+3) = 18x+18
-3(4x-2) = -12x+6
(18x+18) + (-12x+6) = 6x+24
Answer:
the answer is 15m2
Step-by-step explanation:
what you do is the red line in the middle is the surface area and you add those together to get the answer
Y=24 because 60/20 is 3. 3*8 is 24
