3 1/2r=28
7/2r=28
r=(28/1)(2/7)
r=8
The answer is D. hypotenuse ÷ opposite
Answer:
p = 10
Step-by-step explanation:
In order to solve an equation we must isolate the variable we're solving for, p.
We can do this by undoing operations in the equation.
First, multiply both sides of the equation by 14.

This gives you 4 + p = 14
Then, you can subtract 4 from both sides:
4 - 4 + p = 14 - 4
p = 10
Answer:
The required equation is c = 1.59 - s
Step-by-step explanation:
Here, s represents the sales price per pack and c represents the cost saving,
Also, the regular price per pack = $ 1.59,
Since,
Cost saving = Regular price - sales price
⇒ c = 1.59 - s
Which is the required equation that is used to determine how much money is saved if the pack is bought today.
