Yes, it is directly proportional.
Step-by-step explanation:
Since Anna does a sit-up at a certain amount of time, then we have two quantities we are comparing: a sit up and the amount of time it takes.
It is said that the tired she gets, the more time she uses. Therefore, as her tiredness increases, the amount of time also increases. This implies that the quantities are proportional, directly proportional.
When x = 3 z = 57 57/3 = 19
19*8 = 152
So when X is equal to 8, Z is equal to 152.
Answer:
Thank you for being so kind! X=15
Step-by-step explanation:
each expression combined is equal to 180.
so you must put 5x+9+7x-9 and solve to get 15!
5x + 10y + 5z. Distribute the .5 to the number in the parentheses. It basically just cuts the numbers in half.
