The answer would be C. 8.
I would cross multiple the fractions (3*40) and (15 * x)
That would equal 15x= 120
Divide both sides by 15 and you get 8
Or
You could say: what number times 3 gives me 15? The answer would be 5 and then you would divide 40 by 5 to get 8.
Hope the explanation helps :)
Answer:
1. x = 20
2. x = 45
Step-by-step explanation:
First Picture:
Because of vertical angles theorem, ECD is congruent to ACB making ACH 2x
Since a triangle adds up to 180 we can use the equation 2x + 2x + 100 = 180
From this, you will get x = 20
Second Picture:
Because we know that the lines are parallel you can use alternate interior angles theorem and make RST x too
Like the other problem, we can use an equation
In this case it is x + 2x + x = 180
You should get x = 45
Answer:
Step-by-step explanation:
slope= y2-y1 / x2-x1
= -2-5 / 2-3
= -7 / -1
= 1
I believe that she would get $11 back because all you have to do is add to see how much the purchase is going to be and then see there are 4 $20 bills and that equals 80 and then you would subtract 80-69 and get 11
