Answer:

C: 70 Mins

Step-by-step explanation:

1, 20ft*15ft=300ft^2

2, 30ft*25ft=750ft^2

3, 750ft-350ft=450ft^2

4, 450 ft^2 = 30 mins

5, 350ft=750ft=1050ft^2

6, 1050/450=2.3333

7, 30*2.3333=70

8, 70 mins

Write the equation of the line through each point.
Leya [2.2K]

Answer:

The equation would be y = -1/3x + 4

Step-by-step explanation:

The first step to finding this equation needs to be solving the first equation for y so that we can find the slope.

-3x + y = 1

y = 3x + 1

Now that we have the slope of 3, we know the slope of a perpendicular line would be -1/3. This is because perpendicular lines have opposite and reciprocal slopes. We can then use this and the point to solve in point-slope form.

y - y1 = m(x - x1)

y - 2 = -1/3(x - 6)

y - 2 = -1/3x + 2

y = -1/3x + 4

Solve each equation for the unknown <br>1. 5 + y = 7.<br>2. 3.8 = a + 2.5<br>5. + p = 9 1/3 ​
Alexxandr [17]

Answer:

1. 5 + y = 7

⇒ y = 7 - 5

⇒<u>y = 5</u>

2.  3.8 = a + 2.5

⇒ a = 2.5 - 3.8

⇒ <u>a = -1.3</u>

3. 5 + p = 9 1/3 ​

⇒ p = 9 1/3 - 5

⇒ p = 28/3 - 5

⇒ p = 28/3 - 15/3

⇒ p = 13/3

⇒<u> </u><u>p = 4 1/3</u>
