Solutions

⇒ Given

Salary - $ 20

Spends - $ 14

The first step is to subtract 14 from 20. When we do this, we will know how much he saves.

Calculations

20 - 14 = 6

He saves $ 6 each week.

Now we have to find how many times 6 goes into 300. To do this we have to divide.

300 ÷ 6 = 50

<span>It is going to take him 50 weeks. </span>

20-14=6 dollars a week (net)
300/6=50
50*7=350
50 weeks (or 350 days) to save $300.

A 24 inch board is cut into 3 pieces so that the second piece is twice as long as the first and the third is 3 times as long as

Lady_Fox [76]

Answer:

The answer to your question is: first piece = 4 in, second piece = 8 in, third piece = 12 in

Step-by-step explanation:

Data

total length = 24 inches

first piece = x in

second piece = 2x

third piece = 3x

Equation

x + 2x + 3x = 24

6x = 24

x = 24/6

x = 4 length of the first piece

second piece = 2(4) = 8 inches

third piece = 3(4) = 12 inches

What is an equation of the line that is perpendicular to y=−23x+5 and passes through the point (2, 11) ?

hichkok12 [17]

Answer:

The equation would be y = 1/23x - 251/23

Step-by-step explanation:

To start, you need to locate the slope of the first equation. Since the slope is the coefficient of x, we know it to be -23. Now, the perpendicular slope is the opposite and reciprocal of that, which makes the new slope 1/23.

Now that we have this, we can use the point and the slope in point-slope form to get the equation.

y - y1 = m(x - x1)

y - 11 = 1/23(x - 2)

y - 11 = 1/23x - 2/23

y = 1/23x - 251/23
