How would a 75% achievement grade on a test affect a person with a 90 average

Mathematics

Sphinxa [80]3 years ago
8 0

Well, let's see how it'll effect your grade...

75% ÷ 90% = 0.83

0.83 x 100 = 83%

It would effect your grade by 7 percent, lowering it to 83%

I hope this helps!

Dmitry [639]

Answer:

Benny started with 74 cards.

Step-by-step explanation:

To find the answer, the first part with Benny buying eight more baseball cards is unnecessary information. Since his dog ate exactly half of his baseball card collection and he was left with 37 cards, he would've had 74 cards to start with.

What value of c makes the equation true?<br><br><br><br> −3−3/4(c−4)=5/4
Anuta_ua [19.1K]
C = -5/3 = -1 2/3



Write down the equation and solve for c

-3 - 3/4(c-4) = 5/4



Distribute the 3/4

-3 -(3/4)c + 3 = 5/4



Perform the addition of -3 and 3

-(3/4)c = 5/4



Divide both sides by -(3/4)

c = 5/4 / (-3/4) = 5/4 * (-4/3) = -20/12 = -5/3



So the value of c is -5/3. Let's verify it.

-3 - 3/4(-5/3 - 4) = x



Distribute the -3/4

-3 - (3/4)(-5/3) + (3/4)4 = x

-3 +15/12 + 3 = x



Combine terms

15/12 = x



Simplify

5/4 = x
