Answer:

x=7

Step-by-step explanation:

I believe we are solving for x. In that case, let us start by moving 1 to the other side.

\frac{4(x+3)}{5} = 8

Now, we want to get rid of that denominator of 5. Let us multiply both sides by 5:

4(x+3)=40

Now, we may divide both sides by 4 to get rid of the coefficiant:

x+3=10

When we subtract both sides by 3, we get

x=7

<em>I hope this helps! :)</em>

Answer:

P = (\frac{8}{3},\frac{11}{3})

Step-by-step explanation:

Given

X = (1,2)

Y = (6,7)

Required

The point at 1/3 of XY

If the point is at 1/3 for X, then the other end (to Y) is 2/3

So, we have:

m:n = 1/3:2/3

Multiply by 3

m:n = 1:2

The point (P) is calculated using:

P = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})

This gives:

P = (\frac{1*6 + 2*1}{1+2},\frac{1*7 + 2*2}{1+2})

P = (\frac{8}{3},\frac{11}{3})
