Answer:
d = 40 / c
Step-by-step explanation:
There are 10 flower boxes and each holds 4 kilograms of soil. This means Ann will need 40 kilograms of soil.
So the number of bags d depends on how much soil c is in each bag. The equation is 40/c = d
Answer: –9 and 2
Step-by-step explanation:
If Gary lost 17 pounds and gained 8 pound back, then we have
-17 pounds + 8 pounds = -9 pounds.
Therefore the additive inverse of the change in Gary's weight is 9 pounds.
That is, Gary lost 9 pounds of weight.
First thing, you need to transform this equation to the form of y = ax + b
So you get:
2x + 5y = 8
5y = -2x + 8

In the form of y = ax + b, a is the slope.
In

, you can see "

", and always the number before x is the slope
So, the slope of 2x + 5y = 8 is

Hope this Helps :)
The answer to your question is x=3
