52m^2= 2[(x-5)+(x)]. 52m^2= 2(2x-5). 52m^2=4x-10
Step-by-step explanation:
10)-2
11)-11
12)-9
13)75/-25=-3
14)-30/-15=2
15)-20/5-5
=-4-5
=-9
16)90/-45=-2
17)-45/-15=2
18)-15 times 5/25
=-75/25
=-3
19)-15-(-45)/10
=-15+45/10
=30/10
=3
20)5-5/-1
=0/-1
=0
21)-(-15)/5
=15/5
=3
22)-45-15/-15
=-60/15
=-4
23)-15+(-45)/-5
=-15-45/-5
=-60/-5
=12
Have a nice day! :)

The absolute value of a number is always positive. It is the distance the number is away from zero.
|-22| = 22
Well, if 0.4% was defected, then 99.6% of the parts are good, because 100-0.4 is 99.6. Multiply 99.6% with 54650, and you get 54431.4. You should round down, because you can't have parts of parts. So, 54431 parts were good.
C. 2 : 1, because the original ratio would be 8 : 4, but to get it to the correct ratio you must simplify the ratio to 2 : 1.
