5v + 7f =28.70 if f is 2.85
adell [148]
Hey!

First, let's write the problem.
5v+7\left(2.85\right)=28.7
Multiply 7 with 2.85.
5v+19.95=28.7
Subtract 19.95 from both sides.
5v+19.95-19.95=28.7-19.95
5v=8.75
Divide both sides by 5.
\frac{5v}{5}=\frac{8.75}{5}
v=1.75

Let me know if you have any questions regarding this problem!
Thanks!

A line passes through point (-2, 5) and has a slope of 3. Points A(x 3) and B(-2, y lie on the line.
il63 [147K]

Answer:

x = -8/3

y = 5

Step-by-step explanation:

Finding the equation of the line:

y = 3x +c

Substituting (-2,5) into 'y=3x+c':

5 = -6 + c

c = 11

Hence,

y = 3x + 11

For finding x:

Substituting (x, 3) into 'y = 3x +11':

3 = 3x + 11

3x = -8

x = -8/3

For finding y:

Substituting (-2, y) into 'y = 3x + 11':

y = -6 + 11

y = 5

I don't really understand these because our teachers expect me to know this when she didn't teach us this.

First, find the percentage of the price after the sale occures
percent = 100% - 20%
percent = 80%

We need to find the price for the pairs with the percentage above
new price = percentage of new price/percentage of old price × old price
new price = 80%/100% × 55
new price = 4/5 × 55
new price = 44
The new price is $44

Now we estimate how much the tax
tax = 6% × 44
tax = 6/100 × 44
tax = 2.64

Calculate how much Josie will pay
pay = new price + tax
pay = 44 + 2.64
pay = 46.64

Josie will pay $46.64

Each friend would have taken a total of 35 rides each. 

This can be verified by multiplying 35 by 35 to get 1225.
