<span>the additive inverse of 4x is -4x because if you add them together, you get zero. 4x+-4x=0. And the additive incevse of -5 is 5.</span>
Answer:
a. 146
Step-by-step explanation:
{4*[72-6*(3+2)]}-22
=[4*(72-6*5)]-22
=[4*(72-30)]-22
=(4*42)-22
=168-22
=146
1 1/6 hrs.....1 hr = 60 minutes......1/6 hr = 1/6(60) = 60/6 = 10 minutes....therefore, 1 1/6 hrs = 70 minutes
(7/8) / 70 = x / 1....7/8 of the wall to 70 minutes = x wall in 1 minute
cross multiply
(70)(x) = (7/8)(1)
70x = 7/8
x = (7/8) / 70
x = 7/8 * 1/70
x = 7 / 560 reduces to 1/80 <== she paints 1/80 of the wall in 1 minute
We can re-group them to add more easily.
300 + 400 = 700
42 + 16 = 58
700+58 = 758
Answer: 758
