Answer:
Step-by-step explanation:
d=days not used
50-2d = 40-1.5d
subract 40 each side
10-2d =1.5d
10= 0.5d
20=d
After 20 days the value of the gift cards will be equal.
20*2=40 50-40=10 ($10)
20*1.5=30 40-30=10 ($10)
each card will have a value of $10 after 20 days,when both cards have equal value
Answer:
No, bacause each X (first value), need to have just once Y value (second one). Here you have two values for 3 (4 and 4)
Answer:
0/-2; undefined
Step-by-step explanation:
What is the question? If you are only trying to expand the
expression then the answer would be:
1/4 (5y-3)+ 1/16 (12y+17)
(5y/4) – (3/4) + (12y/16) + (17/16)
1.25y – 0.75 + 0.75y + 1.0625
2y + 0.3125
If you are trying to find for y, then you forgot to equate
it to 0, that is:
2y + 0.3125 = 0
2y = -0.3125
<span>y = 0.15625</span>
The first one is 6 gallons and the other one you can’t because if josh gets 3 gallons of gas he’s going to have to pay $8.25 but if he gets 4 gallons he’s going to have to pay $11
