Answer:
-9/7
Step-by-step explanation:
Hello :
the solution is : <span>(3, -1)
put x= 3 and y = -1
you have : 3-(-1) = 4 and 3+(-1) = 2 ..... right</span>
D/60 + D/50 = 2D/55 - 1/2
find common denominator ( 3300)
3300/60 = 55
3300/50 = 66
3300/55=60
so then you get 55D +66D= 60(2D)-1650
121D=120D-1650
D=1650 miles
check
1650/60 =27.5, 1650/50 = 33, 27.5 + 33 = 60.5 hours total
1650/55 = 30, 30 x 2 = 60
60.5-60 = 0.5 longer
so distance = 1650 miles
THIS IS AN EXAMPLE:
Answer: Bradley scored 854 points and Harner scored 748 points.
Step-by-step explanation:
Start by representing the problem mathematically. "B" will represent Bradley's score, and "H" will represent Harner's score.
B+H=1602 represents that the sum of the scores is 1602.
B-H=106 represents that Bradley has 106 more points than Harner.
Now, combine the like terms in the two equations to get 2B=1708 . Now divide each side by two to find that Bradley scored 854 points.
Now, we can just subtract Bradley's score from the total score to get Harner's score. 1602-854=748, so Harner scored 748 points.
There ya go, Hope, this helps
