Write a real world problem that can be modeled by the equation 1.25x = 0.75 x + 50

Radda [10]

Subtract 0.75x from both sides
1.25x-0.75x = 0.5x
0.5x= 50
Divide 0.5 from both sides
X= 100

Help me with my math homework please

21-
x is 18
$x + 3x + 18 = 90 \\ 4x + 18 = 90 \\ 4x = 90 - 18 = 72$
$x = \frac{72}{4} =18$

22- x is 50.5
$x + 58 + x + 21 = 180 \\ 2x + 79 = 180 \\ 2x = 180 - 79 = 101$
$x = \frac{101}{2} = 50.5$

23- x is 196/3
$2x + 8 + x - 24 = 180 \\ 3x = 24 + 180 - 8 = 196\\ x = \frac{196}{3}$

24- x is 88.5
$x + 15 + x - 12 = 180 \\ 2x = 180 - 15 + 12 = 177\\ x = \frac{177}{2} = 88.5$

25- x is 131

y is 180- 131=49

good luck
