Answer:
d = -10/7 = -1 3/7
that is the answer for number 1.
For number 2. the answer is U = 13/4 = 3 1/4 = 3.25
step by step explanation
multiply both sides of the equation by 4 the least common multiple of 2,4
2 (5 x 2 + 1) -4 u = 9 then multiply 5 and 2 to get 10
2 (10 + 1) -4u =9
then add 10 and one to get 11
2 x 11 -4u =9
then multiply two and 11 to get 22
22 -4u = 9
then subtract 22 from both sides
subtract 22 - 9 to get -13
-4u = -13 then undo multiplication by dividing both sides divide both sides by 4-13 / -4 can be divided by positive 13/4
your answer is 13/4
Divide 300 by 8 to find the unit rate
300/8= 37.5
He travels 37.5 miles per hour
If he travels 37.5 miles per hour, to find the amount in 4 hours we would do 37.5 times 4
37.5×4=150
In 4 hours he travels 150 miles
I think the answer would be c but I'm not positive
I hope I help :)
