If x=−1and y=−3, then 5(x2−7+y)=

-60

Step-by-step explanation:

(plug in x= -1 and y= -3)

your equation will look like this-

5 ((-1)2-7+(-3))

solve using PEMDAS

it will be a cylinder. with a diameter of 8 and 4 single pieces high

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
