Answer:
(a) –2.65
(b) 1/8
(c) 14.28
(d) –7 9/10
Step-by-step explanation:
(a) 5.8 + (–8.45) = 5.8 – 8.45 = –2.65
(b) –3/4 + 7/8 = –6/8 + 7/8 = 1/8
(c) –13.62 – (–27.9) = –13.62 + 27.9 = 14.28
(d) –3 2/5 – 4 1/2 = –17/5 – 9/2 = –34/10 – 45/10 = –79/10 = –7 9/10
Answer: The highest labor cost per hour that he can afford is $34
Step-by-step explanation:
Hi, to answer this question we simply have to solve the inequality:
4x + 260 < 400
4x < 400-260
4x < 140
x < 140/4
x < 35
Since x represents the labor cost per hour , The highest labor cost per hour that he can afford is $34 (using whole numbers, because x must be less than 35, not less or equal)

D
19/50 multiply 2 on numerator and denominator it becomes 38/100
38/100 = 0.38 since 38/100 is 38 divide by 100 which is 0.38
<span>The volume of a rectangular prism = its base area * height
substitute:
</span>
x3 – 3x2 + 5x – 3 =<span> (x2 – 2) * h
h=</span> (x3 – 3x2 + 5x – 3)/<span>(x2 – 2)
so you can use the long division</span>
Try 226.08. I'm pretty sure that's right.
