Answer:
A. =
Step-by-step explanation:
Find a common denominator, then compare.
To get 20/10 as a mixed number you would have to take 20 and divide it by 10. Once you do that your answer should be 2.
Y=1.47x
X is the number of erasers bought
Answer:
r= 0
Step-by-step explanation:
Cancel equal terms on both sides of the equation:
= 3r - 5r = -4r
collect like terms
= -2r = -4r
move variable to left and change its sign
= -2r + 4r = 0
collect like terms
= 2r = 0
divide both sides of the equation by 2
r=0
