Which of the following equations is equivalent to 4x-2=38 A. 5x=-50
B. X-20=30
C. 5x=50
D. 2x=10

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

r = 78539458390583095803458309458039485093485 or just 3

step-by-step explanation:

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
