Answer: C
Step-by-step explanation:
It is C because you are adding money to something you already have, hence positive integer
Answer:
To find the mpg all we have to do is divide the numbers in the ratio.
119 miles / 3.5 gallons = 34 mpg
77 mi / 2.2 gal = 35 mpg
153 mi / 4.25 gal = 36 mpg
H = cost of horseback riding per hr, p = cost of parasailing per hr
3h + 2p = 192...multiply by 2
2h + 3p = 213..multiply by -3
------------------
6h + 4p = 384 (result of multiplying by 2)
-6h - 9p = - 639 (result of multiplying by -3)
-----------------add
-5p = - 255
p = -255/-5
p = 51 <== cost of 1 hr for parasailing
3h + 2p = 192
3h + 2(51) = 192
3h + 102 = 192
3h = 192 - 102
3h = 90
h = 90/3
h = 30 <== cost of 1 hr of horseback riding
If you have a part and a whole you can subtract the part from the whole to find the other part.
I'm not sure about it, but that's my best guess ;3
Good luck!
First remember that sum means to add. now think about the equation. we need to find 3 numbers that equal 159 when added together. And they are all consecutive odd numbers. so let's call the first number X. the second number would be X+2 since we have to jump over 1 even number. The third number would be X+4 since we have to jump over 2 even numbers. so now an equation to represent this would be X+(X+2)+(X+4)=159. Add like terms, and remember order of operations. if you need help getting the answers leave me a comment.
