Let x be the number of hours spent on the local highways and y be the number of hours spent on the interstate highways. They spent two more hours on the interstate highway than the local highways, so y = x + 2. The distance formula is d = rt (distance = rate*time), so the distance the team traveled on the local highways alone was 45x miles. Likewise, the distance the team traveled on the interstate highways alone was 55y miles. In total, they traveled 560 miles, so 45x + 55y = 560.
Solve the system of equations using substitution.
45x + 55y = 560 (substitute x + 2 for y) 45x + 55(x + 2) = 560 45x + 55x + 110 = 560 100x + 110 = 560 100x = 450 x = 4.5 hours on the local highways
So the answer would be 4.5 hours. That is the answer if my math is correct if it is wrong I am sorry but I think it is correct I am just trying to help.
Answer: Taylor is 14 and Jessi is 13
Step-by-step explanation:
Since you can't divide 27 by 2, you would most likely break it in half. SInce the question states that Taylor is still older, she would be 14, and Jessi 13.
Answer:
a).no sugar=1. flour=3 1/2
B). sugar= 1 1/2. Flour= 5 1/4
c) your just simplifying to the smallest possible number
Step-by-step explanation:
1/2 doubled= 1 (1/2+1\2)
1 3/4= 7/4
7/4 doubled= 14/4=3 2/4= 3 1/2(1 1/3+1 1/3)
Answer: B
Explanation: an isosceles triangle has 2 sides that are the same, so if the base angles are both 34° then you can multiply that by 2 to get 68°. After that you know that you're still missing one of the angles so that missing angle is x. The equation you can set up to solve for x is the following: 68° + x° = 180°
Hope this helped! :)
