All you have to do is multiply 10 x 407.7 = 40.77 which is the answer.
But if you want to do it an a easier way you just move the decimal point one time to the left to get your answer so you wont need to use a calculator to figure that out.
Hope that helped!!

The answer is 4077. All we have to do to find the answer is do inverse operations. Since the opposite of division is multiplication we would have to multiply 407.7*10 which equals 4077. To check our answer we simply divide 4077/10 =407.7 and we find that it matches! Hope this helps!
5x+3y=17
2) x+3y=10
2x-3y=2
3) 4x+3y=-1
2x+5y=3
4) 5x+7=6
10x-3y=46
5)4x-5y=-11
2x+y=5
6)3x-2y=0
9x+8y=7
Hey there! :) In order to find the perimeter, you must add all 4 sides. You first do 16.8 + 16.8 + 9.6 + 9.6 which is 52.8.
Hope it helps!
SOLVE THE EQUATION.
WILL GIVE BRAINLIST AND THANKS
Answer:
x = -5
Step-by-step explanation:
-9(x+3) = -9x-27
Add 27 onto both sides and get -9x = 45
Divide -9 on both sides and you'll see that x = -5 because 45/-9
Answer: X=-5 distribute the -9 to x and 3 move the 3 over to the 18 and - 18-3 then dived -9x/15
