Answer:
Step-by-step explanation:
Thinking of this in terms of words, we are looking to solve the equation:
"The price Andre paid for the car is 65% of the original $7200 price" which in algebra-speak is
p = .65(7200) where p is the price Andre paid (our unknown), the word "is" indicates an equals sign, .65 is 65% as a decimal, the word "of" indicates multiplication, and the original price is...well, the original price.
Solving for p:
p = $4680
The three little lines through the sides of the triangle mean all three sides are equal. Because all three sides are equal the three inside angles would aso be equal.
The three angles of a triangle need to equal 180, so we can divide 180 by 3 to find what each angle is:
180 / 3 = 60.
Now we can set the equation with x in it to equal 60:
7x +4 = 60
Subtract 4 from each side:
7x = 56
Divide each side by 7:
x = 56 / 7
x = 8
Just put them together. The subtraction sign is a negative sign. First step: 8v-10v= -2v Second Step: 8j-6j= 2j So your final answer would be: 2j-2v
