David's score on his fifth test would be an 87. If you add up all the scores from his first to his fourth test, it would 363. However, since there are five tests, in order to get a 90 percent, the sum of all five test scores would be 450. 450 - 363 = 87.
Answer:
$70
Step-by-step explanation:
Middletown Equation:
1c +50 = T
Sweet Shoppe Equation:
2c + 30 = T
Set equations equal to one another and solve for first for cupcakes then for cost.
1c + 50 = 2c + 30
c+ 20 = 2c
20 = c (twenty cupcakes would be ordered)
Now insert into either equation ( or both to check)
1(20) + 50 = 70
2(20)+ 30 = 70
Total cost would be $70

If the 3 is an exponent, then the person above me is right.
Answer:
<h2>(f/g)(x) = 3</h2>
Step-by-step explanation:
f(x) = 9x + 3
g(x) = 3x + 1
To find (f/g)(x) divide f(x) by g(x)
That's

Factorize f(x)
f(x) = 9x + 3 = 3(3x + 1)
So we have

Simplify
We have the final answer as
<h3>(f/g)(x) = 3</h3>
Hope this helps you
Solution
For this case we have the following amount: 35 pints
We want to convert this into quarts so we can do this:

Then the answer rounded to the nearest hundredth is:
17.50 quarts
