Answer:
A
Step-by-step explanation:
x/y - x/y-1
But remember the fraction with the bigger denometer is the smaller number
x/y is the smaller number
therefore the answer is:
x/y-1 - x/y or A

Answer:
135
Step-by-step explanation:
The supplement of an angle is 80° less than three times the measure of the complement of the angle find the measure of the supplement of the angle
Two Angles are Supplementary when they add up to 180 degrees.
Two Angles are Complementary when they add up to 90 degrees
Let the angle = x
Supplement of the angle = y
The supplement of an angle is 80° less than three times the measure of the complement of the angle find the measure of the supplement of the angle
x - 180 = 3(x - 90)
x - 180 = 3x - 270
Collect like terms
3x - x = 270 - 180
2x = 90
x = 90/2
x = 45
x+ y = 180
45 + y = 180
y = 180 -45
y = 135
Step-by-step explanation:
1. 4/10 + 15/10
The two fractions have like denominators so you can add the numerators.
Then:
4+15/10=19/10
This fraction cannot be reduced.
The fraction
19/10
is the same as
19÷10
Convert to a mixed number using
long division for 19 ÷ 10 = 1R9, so
19/10=19/10
Therefore:
4/10+15/10=1 9/10
2. 50/20+60/20=5 1/2
