Answer:
The cost of labor per hour is $105.
The expression is 4x + 77 = 497
Step-by-step explanation:
The expression is 4x + 77 = 497, where 4x represents the cost of labor per hour, 77 is the cost of the parts, and 497 is the total.
4x + 77 = 497
4x + 77 - 77 = 497 -77
4x = 420
4x/4=420/4
x = 105
Answer:
30 and 60
Step-by-step explanation:
1. "The measure of angle is twice the measure of its complement" means that one angle is twice the amount of another angle, and when both of them are added together, they equal 90°.
2. 60 is twice the amount of 30, and when both of them are combined, they equal 90°.
Therefore, the answer is 30 and 60.
Answer:1 1/20
Step-by-step explanation:
2 5/8 x 2/5
(8x2+5)/8 x 2/5
21/8 x 2/5
(21 x 2) ➗ (8 x 5)
42 ➗ 40
42/40=21/20=1 1/20
Since you have to distribute both numbers, you'll end up with x^2-3x+4x-12 then simplify and it is x^2+x-12
