A plumber earns $40 an hour and the plumber's helper earns $25 an hour. One day the helper starts work at 8 a. m. and the plumber starts at 10 a. m. They both continue working until 4 p. m. The following equations can be used to determine each person's earning, where a represents the amount earned and x represents the number of hours that have passed since 8 a. m. PLUMBER: a = 40(x - 2)
HELPER: a = 25 x

At what time will the helper and the plumber have earned the same amount of money?
A: 1:13 p. m.
B: 1:20 p. m.
C: 3:13 p. m.
D: 3:20 p. m.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
