For eliminating you need to have a variable that cancels the other out and in this case 2x and -2x do. Then you want to take -3y+9y and add the numbers after the equal sign. -9+3
Plug 4 in for x
4(4^3)+4(4)
4(64)+16
256+16=272
18.67 to the nearest hundredth would be 18.67 because there is no number that is a thousandth so there for another way of saying it is 18.670
The measure of each of the angles formed is 32 degrees.
Answer:
x = -15
Step-by-step explanation:
Subtract x on both sides
x + 5 = -10
Subtract 5 on both sides
x = -15
Check work:
2(-15) + 5 = -15 - 10
-30 + 5 = -25
-25 = -25
