Find the Greatest Common Factor (GCF)

GCF = 5ab

Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

5ab(15a^b/5ab + -10ab^2/5ab)

Simplify each term in parentheses

<u>5ab(3a - 2b)</u>

A truck can be rented from Company A for ​$100 a day plus ​$0.20 per mile. Company B charges ​$60 a day plus ​$0.70 per mile to
denis23 [38]

Answer:

Step-by-step explanation:

First, we write the rental cost with each company:

Company A Pa = 100 + 0.2*m

Company B Pb = 60 + 0.7*m

Where m: miles travelled

Now, we need to find "number of miles in a day at which the rental costs for Company A and Company B are the same". This means Pa = Pb. Then:

100 + 0.2*m = 60 + 0.7*m

Solving the equation for m by taking 0.2m and 60 on both sides:

100 + 0.2*m - 0.2*m - 60 = 60 + 0.7*m - 0.2*m - 60

40 = 0.5*m

Finally, dividing 0.5 on both sides:

m = 80

Assoli18 [71]

Answer:

Both Amy and Fraser walk distances equal to the radius of the lawn.

Step-by-step explanation:

The radius of a circle is a line segment from the center to the outside edge (circumference).

Amy walks from O, the center, to A, along the outside edge, using segment OA.  This is a radius of the circle.

Fraser walks from O, the center, to B, along the outside edge, using segment OB.  This is a radius of the circle.  

Thus the correct answer is that both Amy and Fraser walk distances equal to the radius of the lawn.

Which one is the right answer
Ierofanga [76]

Answer:

90 degrees

Step-by-step explanation:

if you add a line from point B to point D, you will make a square and all sides are equal to 90 degrees.

use angle 3 and 4 which equal 90. divide that by 2 and each side is equal to 45. since we know that all sides are equal, angle 3 is equal to angle 2. so from here you add 45 + 45 and get 90 degrees.
