Answer:
15, 20, 25, 30
Step-by-step explanation:
If want to find the first multiple, we could actually use the equation: x + (x+5) + (x+5+5) + (x+5+5+5) = 90. After simplifying this term, we would get 4x+30 = 90 which then transforms into 4x=60 which simplifys to x = 15. Plug 15 into the original equation, and you would get the multiples 15 + 20 + 25 + 30 = 90.
20 and 24 are both divisible by 2, so divide 20 by 2, which equals 10, then divide 24 by 2, which is 12, now our fraction looks like this... 10/12, 10 and 12 are both divisable by 2, so that now equals 5/6, that is the simplest form for this fraction
Answer:
x = 21
Step-by-step explanation:
1/3(x + 6) = 1/2(x - 3)
(3)1/3(x + 6) = (3) 1/2(x - 3) - multiply both sides by 3 to get rid of the 1/3
x + 6 = 3/2(x - 3)
x + 6 = 3/2 (-9/2) - i distributed the 3/2 into the parenthesis
x + 6 (2) = 3/2 (-9/2) (2) - multiply each side by 2 to get rid of the fractions
2x + 12 = 3x - 9
2x - 3x = -12 -9 - bring the x to one side
-x = -21
-x/-1 = -21/-x
x = 21
