Answer:

x = 16

Step-by-step explanation:

\frac{1}{2} (x + 8) - 16 =  - 4

\frac{1}{2} x + 4 - 16 =  - 4

\frac{1}{2} x + 4 = 12

\frac{1}{2} x = 8

x = 16

Sophia scored 92% in a math test. if the test had 50 question how many did she get right
german

Answer: 46

Step-by-step explanation:

percentage scored = 92

number of correct question = x

total number of questions = 50

The formula for calculating the percentage scored

= number of correct question / total number of questions x 100

That is

92 = \frac{x}{50} x \frac{100}{1}

92 = \frac{100x}{50}

cross multiplying :

100x = 92 x 50

100x = 4600

dividing through by 100 , we have

x = 46

Therefore, she got 46 questions right
