The distance from Rihanna's apartment to the park is (5x+2) miles and the trip from the park to the coffee shop is (25x-8) miles long. It is given that Rihanna always stops halfway through to meet her best friend at a park, this means that the distance from Rihanna's apartment to the park is equal to the distance from the park to the coffee shop. Then
5x+2=25x-8.
Solve this equation, separating variables x in left side and numbers in right side:
5x-25x=-8-2,
-20x=-10,
20x=10,
x=10/20,
x=1/2=0.5.
Answer: x=0.5
Answer:
The answer is that angle 1 is 70 degrees.
Step-by-step explanation:
Alright so all vertical angles are congruent and the sum of all angles IN and triangle equals 180 degrees. So, the angle on the inside of the top of the triangle is 60 degrees because vertical angles are congruent. Now the angle across from the 130 degree angle is 130 degrees, and we know that the outer and inner angles are supplementary, (add up to 180 degrees) so the angle on the inside is 50 degrees. Then, all angles of a triangle equal 180 degrees therefore, 180-(60+50)= the final angle. Now 70 degrees is the last angle and this angle is vertical to angle 1 which means that angle 1 equals 70 degrees.
7+(x+5) would be the answer because sum means addition and it says x and 5. then it says 7 plus that so you put 7. In reality you wouldn't need parenthesis, but if you want it to match the phrase, you can put it in parenthesis.
First question:. A and D. Second question: B and C .
Ok so Jessica bought M pens, which cost $6.70 each.
She also bought 4 fewer pencils than pens, or (M-4) pencils, at $3.50 each.
So in total, she spent:
6.7M + 3.5(M-4)
= 6.7M + 3.5M - 14
= 10.2M -14
So she spent $(10M - 14) on pens and pencils.
Hope this helped
