Question

Which 2 number have the mean of 10 and range of 4

Answer 1

Answer:

12 and 8

Step-by-step explanation:

→ Set up two equations

x - y = 4

$\frac{x+y}{2} =10 \\ \\x + y = 20$

→ Add the 2 equations together

2x = 24

→ Solve for x

x = 12

→ Substitute into original equation

12 - y = 4

→ Solve

y = 8
