.50 + .40m  = .48m     where m is the number of minutes that equalize the cost......subtract .40m  from each side

 

.50  = .08m     divide both sides by .08

 

.50 /.08  = m   = 6.25 minutes

Answer:

Step-by-step explanation: How do you find the 3rd angle of a triangle?

Image result for im not sure on how to do this If one angle of a triangle is 30° more than twice another angle, and the third angle is equal to the sum of the first two angles, find the measure of each angle.

The three angles of any triangle add up to 180 degrees. Since you know two angles (35 and 40), add them together, then subtract the total from 180 to determine the degree of the third angle.

2x+2y= 24 <br> x=3y <br> What is the value of x+y?
natita [175]

Answer:

x = 9

y = 3

Step-by-step explanation:

2x + 2y = 24 is the same as x + y = 12

using substitution, x = 12-y

12 - y = 3y

12 = 4y

y = 3

x = 3(3)

x = 9

Tanzania [10]
4/(1+3) or \frac{4}{1+3}

Addition is the first step for two reasons.
1) the Order of Operations requires you do operations in parentheses first
2) the division cannot be performed until you know what you're dividing
