Question

a. 600
b. 650
c. 700
d. 750

Answer 1

Ricky scored 700 on his fourth SAT math test.

Step-by-step explanation:

To find out what score Ricky got on his fourth SAT math test, we need to subtract the total of his first three scores from the average of all four scores. Let's say Ricky's fourth score is 'x'. We can set up an equation as follows: (1900 + x) / 4 = 650. To solve for 'x', we can multiply both sides of the equation by 4 to get 1900 + x = 2600. Then, subtract 1900 from both sides to find that x = 700. Therefore, Ricky got a score of 700 on his fourth SAT math test.
