The answer, when rounded to the nearest tenth is 19.2

First you can get rid of the decimals by multiplying both numbers by 100, this just makes the whole problem easier. Now all that needs to be done is long division:

(In my work I didn’t realize that it said round to the nearest tenth until I had already gotten past what I needed to find)

Reza and James have started exercising together. When they started, Reza weighed 185 pounds and James weighed 180. After 10 week
olganol [36]
Inequality:
Let
x = pound/week weight loss by Reza
y = pounds/week weight loss by James

Therefore, after 10 weeks the two will weigh as follows:
Reza = 185 - 10x
James = 180 - 10y

But, Reza is said to be weighing less than James after 10 weeks. Then, the  inequality will be as follows:
185 - 10x < 180 - 10y

Determination of the constraints:
Solving the inequality written above;
185 - 10x < 180 - 10y
185 - 180 < 10x - 10y
5 < 10(x-y)
0.5 < x - y

Therefore,
0.5 + y < x or x > 0.5 + y

It can be seen that, for Reza to weigh less than James after 10 week, the loss of weight by Reza must be more than half to the rate of weight loss by James.

GREYUIT [131]

Answer:

2 km

Step-by-step explanation:

Since we know that the TOTAL distance from Kensington to Greenville is 4.3 km, and we also that the distance from Kensington to Springfield is 2.3 km, we can subtract these values to find the distance from Springfield to Greenville.

4.3-2.3=2
