It is 2 .............................
48 is 80% of 60
48 of 60 can be written as 48/60
Multiply both the numerator and the denominator by 100
48/60 · 100/100 = 80/100 = .8 = 80%
If you are using a calculator, simply enter 48 ÷ 60 · 100 which will give you 80 as the answer.
Janet = 1/3
Gary = 1/2
(1/3) + (1/2) = 5/6
Let x = time they both can do the job together
(1/2) + (5/6)x = 1
Solve for x to find your answer.
Replace g for -2 and h for 5.
(2(-2) + 9(5) -5) - (6(-2) - 4(5) +2)
Taking this one at a time,
2(-2) = -4, and 9(5) = 45.
6(-2) = -12 and -4(5) = -20
(-4 + 45 - 5) - (- 12 - 20 +2)
Let’s distribute the negative symbol to the right side.
(-4 + 45 - 5) + (12 + 20 - 2)
Then, we solve!
(-4 + 40) + (12 + 18)
(36) + (30)
= 66!
B) -15.6,-12.9,-10.2,-7.5,-4.8
This is an arithmetic sequence.
