Step-by-step explanation:
1/5x-12=0
1/75-12=0
1-900=-899/75
ans=11.99
Answer:
y = 60x + 20
Step-by-step explanation:
The number of hours that we ski is a variable cost where each hour costs $60. On top of that, we have a fixed cost of $20 which stays the same no matter how long we ski.
So we can use an equation to find the totla cost C given the number of hours t as follows:
C(t) = 60t + 20
We can use this equation to find the cost of a skiing session by plugging in some value for t. For example, if we ski for 3 hours:
C(3) = 60(3) + 20 = $200
The equation can also be written using x and y and mean the same thing.
6.70-10.00=3.30
So you get $3.30 as change
Answer:
26
Step-by-step explanation:
to get from -6 to a 0, you add 6. 0+20 is 20, so that is how you get it
