What is the value of y in the equation 4(5y − 8 − 2) = 185 − 15? 8. 5 9. 7 10. 5 42. 5.
Bezzdna [24]

Answer:

10.5 is the answer

Step-by-step explanation:

4(5y−8−2)=185−15

(4)(5y)+(4)(−8)+(4)(−2)=185+−15(Distribute)

20y+−32+−8=185+−15

(20y)+(−32+−8)=(185+−15)(Combine Like Terms)

20y+−40=170

20y−40=170

20y−40+40=170+40

20y=210

20y/20=210/20

y=21/2

y=10.5

The permitir of the garden is (6x+2) units. Find the length of the missing side .
Snezhnost [94]

Answer: ? = x + 1


Step-by-step explanation:

The perimeter of the garden is x + 3x + 1 + x + ?

The perimeter of the garden is also (6x + 2)

Therfore:

x + 3x + 1 + x + ? = 6x + 2

<em>Collect like terms: </em>

5x + 1 + ? = 6x + 2

<em>Subtract 5x from both sides:</em>

1 + ? = x + 2

<em>Subtract 1 from both sides:</em>

? = x + 1

You cannot find ? as a number, only in terms of x.
