Answer:

5 weeks.

Step-by-step explanation:

John can create 3 apps in 6 weeks, so his rate is (3 apps / 6 weeks) =  1/2 app per week.

Ben can do same job i.e. 3 apps in 2 weeks, so his rate is (3 apps / 2 weeks) = 3/2 app per week.

Their combined rate is (1/2 + 3/2) = 4/2 = 2 apps per week.

It means they together can create 2 apps in 1 week.

So, they together can create 10 apps in 5 weeks.

Well idk about geometric theorem or how ever. but, because they have the same line aka the same Slope. The other line is parallel to it. Assuming by the statement, -1/3x has another -1/3x of the same Slope.

Given the equation 6/x=3/k+2, and the constraints x ≠ 0 and k ≠-2, what is x in terms of k?
Veronika [31]

Answer:

A) 2k+4

Step-by-step explanation:

To solve for terms of x, we need to. she sure that x is on its own side while every other term is on the other side.

To start, we will cross multiply. If we have a/b=c/d, then ad=bc

We can perform the same calculation here,

6/x=3/(k+2)

6(k+2)=3x

Divide both sides by 3

2(k+2)=x

x=2k+4
