She can make 40 baskets in 5 hours because in 1 hour she can make 8 so 8 times 5 is 40
20x - 30y = -50 ⇒ 20x - 30y = -50
x + 2y = -1 ⇒ <u>20x + 40y = -20</u>
<u>-70y</u> = <u>-30</u>
-70 -70
y = ³/₇
20x - 30(³/₇) = -50
20x - 12⁶/₇ = -50
<u> + 12⁶/₇ + 12⁶/₇
</u> <u>20x</u> = <u>47¹/₇
</u> 20<u /> 20<u>
</u> x = 2⁷/₂₀
(x, y) = (2⁷/₂₀, ³/₇)
Answer:
The first choice
