Hello there!
28 recipes .......> 100%
15 recipes .......> x%
Cross multiply
28x = 15*100
28x = 1500
x= 1500/28
x ≈ 53.5%
She makes 53.5% of the recipes.
I hope that helps!
Answer:

Step-by-step explanation:
The given expression is

We have to find the value of given expression when -x=-4/5 and y= 1/3.
Substitute -x=-4/5 and y= 1/3 in the above expression, to find the value of given expression when -x=-4/5 and y= 1/3.

After multiplication we get

Taking LCM, we get



Therefore, the value of given expression is
.
Answer:
x = 26 , y = 33
Step-by-step explanation:
3x + 2y = 144 (1)
2x + 5y = 217 (2)
3x + 2y = 144
(divide the equation by 3)
x + (2/3)y = 48
x = 48 - (2/3)y
Plug into (2)
2[48 - (2/3)y] + 5y = 217
96 - (4/3)y + 5y = 217
11y/3 = 217 - 96
11y/3 = 121
y = 121×3/11
y = 33
x = 48 - (2/3)y
x = 48 - (2/3)(33)
x = 48 - 22
x = 26
