Start with the given equation:
$2y+7$
Substitute known values:
$2(-3)+7$
Evaluate:
$-6+7=1$

Similarly:

replace y with -3

2y + 7 becomes 2(-3) + 7 = -6 +7 =1

-4(-3)-10 = 12-10 = 2

All sides of a square and a pentagon are 9 inches long. Are their perimeters the same? Explain

EastWind [94]

No they wouldn't be the same because, the perimeter is adding all sides.

The square has 4 sides so you would add 9, four times.

9 + 9 + 9 + 9 = 36

And a pentagon has 5 sides so you would add 9, five times.

9 + 9 + 9 + 9 + 9 = 45

So, they are not the same.

Hope this helps. :)

What is 11/4-3/8= what is it or get me the right answer

likoan [24]

Answer:

2 3/8 is the answer

Step-by-step explanation:

11/4 - 3/8

We will find the LCM of 4 and 8, which is 8.

We will do 11/4*8, which 8/4 = 2 and 2*11 = 22

Then we will do 3/8*8 = 8/8 = 1 = 3*1 = 3

So the answer will be <u>22-3 </u> = 19

8 = 8

Mixed Fraction = 2 3/8
