Answer:

$17.70

Step-by-step explanation:

Hi,

What you want to do is to find 30% of $59

First, you convert 30% into decimal form by dividing it by 100

30%=0.3


Next, you want to find 30% of 59, so what you do is you take the new decimal form and multiply it by 59

0.3×59=17.7


Ted is saving $17.70

Find the equation of the line with m = 2 and passes through the point ( 4 , − 5 ) . Write your answer in standard form A x + B y
Rudiy27

Answer:

2x - y = 13

Step-by-step explanation:

To write the equation of a line use the formula y - y_1 = m(x-x_1).

Substitute m = 2 and (4,-5).

y --5 = 2(x-4)\\y + 5 = 2(x - 4)\\y + 5 = 2x - 8\\y = 2x -13\\-2x + y = -13\\2x - y = 13

It has to have an average of 10 feet per minute for 5 minutes, which means in five minutes the total of feet would have to be 50.
So you would add all these numbers up and you would get 38.
50 - 38 = 12 so the answer is 12ft
