Solve 2y - 5 over 3 = 4y - 1 over 2

ololo11 [35]

$\frac{2y - 5}{3} = \frac{4y - 1}{2}$
$3(4y - 1) = 2(2y - 5)$
$3(4y) - 3(1) = 2(2y) - 2(5)$
$12y - 3 = 4y - 10$
$8y - 3 = -10$
$8y = -7$
$\frac{8y}{8} = \frac{-7}{8}$
$y = -0.875$

Explain your answer, please

Molodets [167]

.1.Scale Factor of Triangle STU to Triangle PQR= 1.5

2.Scale Factor of Trapezoid EFGH to Trapezoid JKLM =2

3. about 90 armadillo

1.Side ST: 15 ÷ Side PQ: 10 = 1.5

2.Side JM: 14 ÷Side EH: 7 = 2

3.843/7=120.428571429

843/4=210.75

210.75-120.428571429=90.321428571

This rounds to 90 armadillo

Hope this helps :3 ❤
