Answer:
15/15 aka 1
Step-by-step explanation:
9/15 and 2/5
keep the 9/15 and then denominator the bottom number has to be the same as the first one so multiply 5 times 3 to get 15 whatever you do to the bottom you have to do to the top so 2 times 3 equals 6.
9/15 and 6/15
9+6 equals 15
15/15 which then equals 1
Rewrite Equations
x=10; y=−5x+30
Step: Solve x=10
for x: x=10
Step: Substitute
10 for x in y=−5x+30:
y=−5x+30
y=(−5)(10)+30
y=−20
(Simplify both sides of the equation)
Answer: x=10 y=-20 (10,-20)
15/16, 7/8, .8
because 7/8=0.875 and .875>.8
15/16 = 0.9375
0.9375> 0.875 > .8
