Alejandro wrote an equation to fit the following scenario.

A person driving a pick-up truck and another person driving a motorcycle arrange to meet at a park. The pick-up truck driver took twice as long to arrive while driving at an average speed of 45 mph. The motorcyclist drove 55 mph and had a 23 miles less to drive.

Alejandro’s work:
t = number of hours for the pick-up truck driver to complete the trip
Equation: 55 (2 t) minus 23 = 45 (t)

Which statements identify Alejandro’s errors? Select the two correct answers.
He should have added the 23 to the motorcyclist’s distance instead of subtracting to balance the equation.
He should have written 45(2t) for the pick-up truck driver’s distance, since the he took twice as long.
He should have written 55(t) for the motorcyclist’s distance since t = number of hours for the pick-up truck driver to complete the trip.
He should have written 55 (one-half t) for the motorcyclist’s distance since it only took half the time as the pick-up truck driver.
He should have translated the scenario as motorcycle distance + pick-up truck distance = 23 since 23 is the distance mentioned.

y-y1=m(x-x1)

y-13=1(x-10)

y-13=x-10

y=x-10+13

y=x+3

When we do that that will give us Y. Minus y sub 1 that's the y-coordinate of our point which is 5 equals the slope of 2.

Answer:

Step-by-step explanation:

In a 30 60 90 triangle, the length of the hypotenuse is twice the length of the shorter leg and the length of the longer leg is /3 times the length of the shorter leg. The hypotenuse is 50, shorter leg is 25, longer leg is 25/3

Answer:

90

Step-by-step explanation:

60+30=90 and you can also just look at it, it’s a 90 angle

Answer:

He loses 4 pounds which is (-4)

Why?

Draw a rectangle.. write 13 on the two longer sides of the rectangle then write 7 on the other two shorter ones. Then add them all up and there you go your answer!

Our equation would be 13 +  13 + 7 + 7 = 40 inches

Step-by-step explanation:

The values of r for which the shaded region will be greater than or equal to 12 square units is;

r ≥ 8

We can see a rectangle and a triangle in the given image.

With the triangle being the unshaded portion of the rectangle.

Thus;

Area of shaded portion = Area of rectangle - area of rectangle.

We know that formula for area of rectangle is;

A_r = length × width

Thus; A_r = 3 × r

A_r = 3r

Area of a triangle is;

A_t = ½ × base × height

A_t = ½ × r × 3

A_t = ½(3r)

Thus;

Area of shaded portion = 3r - ½(3r)

Area of unshaded portion = 1.5r

We are told that the area of the unshaded region should be greater than or equal to 12. Thus;

1.5r ≥ 12

r ≥ 12/1.5

r ≥ 8

Answer:  9.20p [tex]\geq[/tex] 299

           The solution is p [tex]\geq[/tex] 32.5

Step-by-step explanation:

First, you need to get the variable by itself. To do that you do the opposite of multiplication, which is division. 9.20p divided by 9.20 is just p.

Second, whatever you do to one side you have to do to the other, so you divide 299 by 9.20 to get 32.5.

The solution is p  32.5
