Answer:
One serving of law-fat yogurt contains 7.35 g of fat.
Step-by-step explanation:
One serving of
- a certain brand of yogurt contains 12 g of fat
- the low-fat yogurt contains 38.75% less fat
Let x g be the amount of fat in low-fat yogurt. Then
12 g of fat - 100%
x g of fat - 100% - 38.75% = 61.26%
Write a proportion
Cross multuply
One serving of law-fat yogurt contains 7.35 g of fat.
We can make two simple equations to express their ages to each other, then solve for one of the variables. Let n be Nojo's age and j be Jacob's age.
n(j) = 84
n - 5 = j
Use substitution to get only one variable in an equation.
n (n - 5) = 84
n^2 - 5n = 84
Since we have n to the power of 2, this equation has two possible answers, but since we are given four possible answer, just substitute them in the equation until one makes the left side equal 84.
<span>n^2 - 5n = 84
</span>12^2 - 5 (12) = 84
144 - 60 = 84
84 = 84
The answer is C = 12
To solve for how many miles Rachel jogged if she jogged a 1/4 mile trail 8 times, we simply need to multiply the distance she ran each time by the amount of times she ran it.
1/4 * 8 = 2
Rachel jogged 2 miles.
Hope that helped =)
