Answer:

Value of n is 52

Step-by-step explanation:

So you have equation: 6.2n – 3.7n = 85 + 45

First, you need to collect the like terms and add the numbers on the other side: 2.5n=130

Now, you need to divide both sides of equation by 2.5. And you will get the answer. n=52

the mean average distance that jack runs in his last 10 runs is 5.7 miles. work out the distance that he would need to make this

ziro4ka [17]

Answer:

9 miles

Step-by-step explanation:

mean is calculated as

mean = $\frac{sum}{count}$ , then

$\frac{sum}{10}$ = 5.7 ( multiply both sides by 10 )

sum = 57

let x be the distance he needs to cover so mean is 6 , that is

$\frac{sum+x}{11}$ = 6 ( multiply both sides by 11 )

sum + x = 66 , that is

57 + x = 66 ( subtract 57 from both sides )

x = 9

That is he would have to run 9 miles
