Answer:
She will not have enough money
Step-by-step explanation:
0.79x85=67.15
67.15+35=105.15
For standard form, we have to rearrange this equation. We want the variables on one side (also called Slope Intercept Form or Ax + By = C)
Subtract 7x from both sides and 4 from both sides to "swap" the variables and the constant number.
This gives us:
x^2 - 7x = -4
9514 1404 393
Answer:
- inverse operation are used
- the variable needs to be isolated
Step-by-step explanation:
A solution is always of the form ...
variable = something
In order to get this form, the variable needs to be isolated (put by itself on one side of the equal sign).
In general, isolating the variable involves using inverse operations to "undo" whatever is done to the variable. These are generally applied in the reverse order of the operations that are done to the variable. The list of operations done and their order can be identified using the Order of Operations to consider how an equation would be evaluated for some value of the variable.
