Emma got 90% of the questions on her history test correct if she answered 27 questions correctly, how many questions did Emma get wrong?

There were (A) questions on the test so she got (B) questions wrong

Step-by-step explanation:

we can make it as a ratio

90/100=27/total Q

total Q= (27*100)/90=30

So wrong questions=30-27=3

hope this helps!

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
