Ummm I just need to answer questions sorry!!!
72 ÷ o should be the algebraic expression.
Answer:
7⁴ is 2401
1⁵ is 1
Step-by-step explanation:
7x7x7x7 is 2,401
1x1x1x1x1 is 1
In -2x
, the exponent will be dealt with first. With (-2x)
, the multiplication is going to be done first. This is determined because of Order of operations.
<em><u>Answer:</u></em>
<em><u>y = 5, 3; x = 171, 155</u></em>
<em><u>Step-by-step explanation:</u></em>
8y - 15 = y^2
y^2-8y+15=0
y^2-3y-5y+15=0
y(y-3)-5(y-3)=0
(y-5)(y-3)=0
y can be 5 or 3.
x = 180 - (8y - 15)
x = 180 - (8(3)-15)
x = 180 - 9
x = 171
OR
x = 180 - (8(5) - 15)
x = 180 - 25
x = 155
