Answer:
true and the answer would be 45.5
Step-by-step explanation:
Answer:
83
supplementary is two angles that add up to 180 so 180 - 97= 83
The simplified version of this equation would be
-x + y
Answer:
Serina should have solved for x in the second equation because it has a coefficient of 1.
Step-by-step explanation:
we have
----> equation A
---> equation B
we know that
To solve the system of equations in the most efficient way, solve for x equation B and then substitute the value of x in equation A
so
----> equation C
substitute equation C in equation A

solve for y

Find the value of x
substitute the value of y in the equation C

The solution is (3,4)
therefore
Serina should have solved for x in the second equation because it has a coefficient of 1.
112-37=75
75/5=15
So 15 weeks until she has 112 cards
