8(y+4)-2(y-1)=70-3y help pls
jeka57 [31]

Answer:

y = 4

Step-by-step explanation:

8(y+4)-2(y-1)=70-3y

8y+32-2y+2=70-3y

Grouping of like terms

8y-2y+3y=70-32-2

9y=36

Divide both sides by 9

9y/9 = 36/9

9 cancels itself and 9.

y=36/9

y=4

Therefore, y = 4.

Hope it helps.

If so, mark as brainliest.

PLS HELP ME I WILL MARK THE BRAINLIEST
Serga [27]

Answer:

1. 155 yd², 2. 379.54 ft², 5. x = 65.82π

Step-by-step explanation:

1. A = (1/2) · (3 + 13) · 8

A = (1/2)(16)(8)
A = 64
A = bh
A = 13*7
A = 91
64 + 91 = 155
155 yd²

2. A = bh
A = 25x25
A = 625
A = πr²
A = 3.14*12.5²
A = 3.14*156.25
A = 490.625
490.925/2 = 245.4625
625 - 245.4625 = 379.5375
379.54 ft²

3. and 4. Sorry, I don't know how to solve these

5. A = πr²
A = 3.14*7²
A = 3.14*49
A = 153.86
x/154 = 153.86π/360
360x = 154*153.86π
360x = 23694.44π
x = 65.8178889π
x = 65.82π

Hope this helps :)
