Answer:
5y + 3= 14
subtract 3 from each side
5y=11
divide each side by 5
5y/5=11/5
y=11/5 or 2.2 or 2 1/5
Hope This Helps!!!
2.2
Step-by-step explanation:
Properties needed:
First we need to subtract 3 from both sides because of <u>subtraction property of equality</u> to make both sides <u>equal</u>.
5y + 3 = 14
<u> -3 -3</u>
5y = 11
Then we need to divide 5 from both sides (<u>division property of equality</u>) to get y.
And we get 2.2

Have a great day!
x = 1/2, y = 17/2
x = -3, y = 12
50.24
1/4x3.14xr^2
r=16 because of the length
90/360= 1/4
so
1/4x3.14x16^2/4
=50.24
4 is our denominator because of the denominator on the fraction
