Answer: B. 3 3/4
Step-by-step explanation:
From the question, we are told that Joanna is making a recipe that uses 1 1/2 teaspoon of salt for every 2 cups of sugar. Since, uses 1 1/2 teaspoon of salt for every 2 cups of sugar, 1 cup of sugar will use 1/2 of 1 1/2 teaspoon of salt. This will be:
= 1/2 × 1 1/2
= 1/2 × 3/2
= 3/4 teaspoon of salt.
We then multiply the value used for a cup of sugar by 5 since Joanna increases the recipe to use 5 cups of sugar. This will be:
= 3/4 × 5
= 15/4
= 3 3/4
Complimentary angles are 2 angles, when added, add up to 90 degrees. So when one angle = x, its complimentary angle = (90 - x)
the measure of an angle, lets call it x, is 8 times as great (means u multiply it by 8) as the measure of its compliment...
x = 8(90 - x)
x = 720 - 8x
x + 8x = 720
9x = 720
x = 720/9
x = 80 <=== the measure of the angle is 80 degrees
its compliment is 90 - x = 90 - 80 = 10
Answer:
-72=-12y-20x
Step-by-step explanation:
-72=2y^2-16y-20x
square the 2 keeping the variable
-72=4y-16y-20x
Then combine like terms in this case the numbers followed by y's
-72=-12y-20x
This is the standard form as there is nothing else you can combine to break this down any further
Answer:
M and N
Step-by-step explanation:
You would take 175 and multiply it by 0.20 which is 35. The you would subtract 35 from 175 because it is marked down so you would get 140. Next, you would take 140 and multiply it by 0.10 and get 14. Finally subtract 14 from 140 to get your answer which would be $126.
