Answer:
I'd say 4 and 9
Step-by-step explanation:
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

A
Step-by-step explanation:
<em>I just did this one</em>
Step-by-step explanation:
4x+3+63+90=180°
4x+156=180°
4x=180-156
4x=24°
x=<u>2</u><u>4</u>
<u> </u><u> </u><u> </u><u> </u><u> </u>4
x=12° ans
hope it is correct.
