Subtract 350 from both sides then divide both sides by 25.
(c-350)/25 = h
46%d+57%y=55%x42
x+y=42
Find y
x=42-y
46%(42-y)+57%y=23.1
19.31-46%y+57%y=23.1
11%y=23.1-19.31
11%y=3.79
y=34
The answer is D
Answer:
B: billie's solution is incorrect since she didnt
subtract 36 from both sides
Step-by-step explanation:
on the second step, she added 36 on the right.
This is incorrect because when changing one
side on an equation you must change the side
in the same way.
Given :
- The length of a rectangle is 4m more than the width.
- The area of the rectangle is 45m²
⠀
To Find :
- The length and width of the rectangle.
⠀
Solution :
We know that,

So,
Let's assume the length of the rectangle as x and the width will be (x – 4).
⠀
Now, Substituting the given values in the formula :







⠀
Since, The length can't be negative, so the length will be 9 which is positive.
⠀
