A + b = 6
a - b = 4
We substract those equations, we get:
2b = 2 (dividing both sides with 2)
b = 1
a = b + 4 (look at second aquations)
= 1 + 4
= 5
Answer:
Step-by-step explanation:
hi there.
Answer:
89.10 / 4.95 is 18. so the first one is 18.
6 and 9, so we have to find the LCM. 6,12,18 and 9,18, so the first one to get a red and blue cap is the 18th bottle.
We know that the 18th bottle will get a red and blue, so then we have to find the LCM of 18 and 10. 18,36,54,72,90 10,20,30,40,50,60,70,80,90.
The first one to get all three is the 90th bottle.
Hope this helps plz hit the crown :D
Answer:
the number of months in which there membership cost would remain the same is 4 months
Step-by-step explanation:
The computation of the number of months in which there membership cost would remain the same is shown below:
Let us assume the number of months be M
For Gym 1, the total cost is
= $108 + 32M
And, for Gym 2, the total cost is 59M
Now equal these two gyms cost
59M = $108 + 32M
59M - 32M = $108
27M = $108
M = 4 months
Hence, the number of months in which there membership cost would remain the same is 4 months
Let x = the number of ride you went on
$79 = $15 + $8x
To solve for how many rides you went on, subtract 15 from each side.
$64 = $8x. Divide each side by 8.
8 = x.
You went on 8 rides
