Answer:
Step-by-step explenation . First you know that the amount of time she trained for the marathon is 125% of the time she trained last month. We also know that she trained 80 hours last month. And the question wants us to know how many hours she trained this month. So we do 100% =x
And 125% = 80 so we cross multiply it becomes 100 X 80 =125x witch eaquals to 8,000 divided by 125 witch is 64. So the final Answer is 64 . IF I AM CORRECT PLEASE MARK BRAINLIEST.
We want to write a linear equation for the recipe that describes the amount of oil that we need in terms of the vinegar.
The linear equation is: L = 3*V
So we know that the recipe calls for 1/3 tbsp of vinegar for every tbsp of oil.
Defining:
- V = amount of vinegar used
- L = amount of oil used.
The original equation is written as:
V = (1/3)*L
Now we want to rewrite this for L, this means, isolating L.
To do that we just multiply both sides by 3, so we get:
V*3 = (1/3)*3*L
V*3 = L
L = 3*V
This equation says that we will use 3 times more oil than vinegar.

Answer:
h(5) = 15
Step-by-step explanation:
h(x) = -2 + 5
h(5) = -2(5) + 5(5)
h(5) = -10 + 25
h(5) = 15
So the man's age is divisible by 3, 5, and 7 but not by 2, 4, 6, or 8.
3 * 5 * 7 = 105
105 is not divisible by 2, 4, 6, or 8.
Not sure if any lower ages are there, but since the man is 105 years old, you would receive $105.
