Lets x = # of hours
Powersports Plus: $30 an hour plus a non-refundable deposit of $50.
Write an expression to show how to calculate the cost of Powersports Plus.
30x + 50
Sun & Surf: $20 an hour plus a non-refundable deposit of $80.
Write an expression to show how to calculate the cost of Sun & Surf.
20x + 80
Next, set the 2 expressions equal to each other.
30x + 50 = 20x + 80
Solve:
30x + 50 = 20x + 80
10x = 30
x = 3
Two companies cost Kyle the same amount of money at 3 hours
Odd numbers are not divisible by 2. Only even numbers are visible by 2. Such as, 4,6,8.
Multiples of 10 do always end in 0.
& i'm not so sure about the last one.
Here are some solutions: (there are actually an infinite amount of them)
x = 0 , y = 7
x = 1 , y = 8
x = 2 , y = 9
x = 3 , y = 10
x = 4 , y = 11
x = 42 , y = 49
x = pi , y = pi + 7
The answer to your question is 24
Well a difference is the difference between them. difference means subtraction. So so a difference can be written as:
40.67 - (-41.29)
If you subtract a negative number you really add it. to make sense of this you could say 40.67 is 40.67 units away from zero in the positive direction. whereas -41.29 is 41.29 units away in the negative direction. since they go in opposite directions away from zero that means that thw length between them is extended and must then be added together. So
40.67 + 41.29 = 81.96
