÷
Step-by-step explanation:
÷
Five eighths times seven elevenths =
5/8 x 7/11 =
35/88
Answer:
x = 1, y = -5
Step-by-step explanation:
2x + 5y = (-23) (1)
5x + 13y = (-60) (2)
Multiply (1) by 5 and (2) by 2 to eliminate x
10x + 25y = -115 (3)
10x + 26y = -120 (4)
Subtract (3) from (4)
26y - 25y = -120 - (-115)
y = -120 + 115
y = -5
Substitute y = -5 into (1)
2x + 5y = (-23)
2x + 5(-5) = -23
2x - 25 = -23
2x = -23 + 25
2x = 2
x = 2/2
x = 1
x = 1, y = -5
Answer: No, he needed to apply the exponent to all factors in the product in the second step.
