Answer:
600, 150
Step-by-step explanation:
Kyle is x
ken is y
x = 4y
x+y = 750
replace x with 4y
4y + y = 750
5y = 750
y = 150
so ken earned 150
x + 150 = 750
x = 600
so Kyle earned 600

Answer:
1,-10 and 2,-8
Step-by-step explanation:
If you substitute each answer choice:
6+-10=4
12+-8=4
12+8=4
6+2=4
The only ones that would make sense are the first and second one.
2√72 / √8 ± √2
If the denominator is √8 + √2,
2√72 / √8 + √2
= 2√(2*2*2*3*3) / √(2*2*2) + √2
= 2*2*3√2 / 2√2 + √2
= 12√2 / 3√2
= 4
