Answer:
3
Step-by-step explanation:
Get rid of fractions:
Multiply the whole equation, i.e. all terms both sides of the equals sign, by the denominator or the lowest common multiple of all denominators if there are multiple fractions in the equation;
In this case, only one term is a fraction and therefore has a denominator (i.e. 7), so it is this number we multiply the equation by to get:
7(y) = 7(-³/₇.x) + 7(3)
7y = -3x + 21
3x + 7y = 21
Answer:
m = ![\frac{-1}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B-1%7D%7B8%7D)
Step-by-step explanation:
3x + 24y = 24
⇔ 3x + 24y - 3x = 24 - 3x
⇔ 24y = 24 -3x
⇔
Thus,
is the slope of 3x + 24y = 24

Answer:
49%
Step-by-step explanation:
First find how much Alice is paying for the all three service currently.
Amount paid by Alice at present= 59 + 49 + 69 = $ 177
If she switches to 90 NOW plan, then the amount saved = 177 - 90 = $ 87
Percentage of savings = (saved amount ÷ total amount she was paying at present) * 100
![= \frac{87}{177}* 100\\\\= 49.15](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B87%7D%7B177%7D%2A%20100%5C%5C%5C%5C%3D%2049.15)
= 49 %
