5x = 4y - 3
The correct answer is D. 5x - 4y = -3
This is because standard form is the form ax + by = c, where a, b, and c are coefficients or constants of the variables x and y. Thus, Answer D (above) is the correct answer to this problem, as it is the only option that fits this.
X + 2y = -4
-x -x
2y = -x - 4
Divide all by 2
y = -x/2 - 2
y = (-1/2)x - 2
The answer are
1) gain
Because they asked the price of detergent per load
2) 0.38 per dollar
In this we have to divide 9.25/25
You can solve this by cross multiplying. 20 ounces/$7=x ounces/$17. multiple $17 by 20 ounces and $7 by x ounces. (17x20=7x). 17x20=340, so 340=7x. Divide both sides by 7, and you will get x equals about 48.6.
Answer:
I only know one way and its x = 7
Step-by-step explanation:
20 = 5( x -3 )
20/5 = x- 3
4 = x - 3
4 + 3 = x
7 = x
