Answer:
x = 75
Step-by-step explanation:
Given information from the question:
x - 3y = 30
y = 15
We can substitute y = 15 into the equation to find x.
x - 3(15) = 30
x - 45 = 30
x - 45 + 45 = 30 + 45
x = 75

Answer:
9/10 in simpliest form is 9/10
Step-by-step explanation:
In order to simplify a fraction there must be:
1. A number that will divide evenly into both the numerator and denominator so it can be reduced. No such number exists for 9 and 10.
or
2. The numerator must be greater than the denominator, (an improper fraction), so it can be converted to a mixed number. 9 is not greater than 10.
9/10 as a decimal: 0.9
9/10 as a percent: 90%
