On a coordinate plane, a line is drawn from point a to point b. point a is at (7, negative 2) and point b is at (negative 8, neg
dimaraw [331]

The coordinate of the partition c on the line segment is (1.2, -4.7)

<h3>How to determine the coordinates of the partition?</h3>

The coordinates are given as:

A = (7,-2)

B = (-8,-9)

m:n = 5:8

The coordinate of the partition is calculated using:

(x,y) = \frac{1}{m + n} * (mx_2 + nx_1, my_2 + ny_1)

So, we have:

(x,y) = \frac{1}{5 + 8} * (5 * -8 + 8 * 7, 5 * -9 + 8 * -2)

Evaluate the sum and products

(x,y) = \frac{1}{13} * (16, -61)

Evaluate the product

(x,y) = (1.2, -4.7)

Hence, the coordinate of the partition on the line segment is (1.2, -4.7)

Calculate 7x +5 - 3x - 7 = 10
vredina [299]

You answer is 3 and here's why...

7x + 5 - 3x - 7 = 10

First you must collect like terms

And that gives us

4x - 2 = 10

Next you must simplify by removing additives

4x - 2 + 2 = 10 + 2

4x = 12

Now you must divide

4x/4 = 12/4

x = 3

1.06(12.95+x)=31.27 solve for x
OverLord2011 [107]

Answer:

<h2>x = 16.55</h2>

Step-by-step explanation:

1.06(12.95 + x) = 31.27

<u>Multiply the terms in the bracket</u>

That's

13.727 + 1.06x = 31.27

<u>Subtract 13.727 from both sides</u>

That's

13.727 - 13.727 + 1.06x = 31.27 - 13.727

1.06x = 17.543

<u>Divide both sides by 1.06</u>

That's

\frac{1.06x}{1.06}  =  \frac{17.543}{1.06}  \\ x =  \frac{17.543}{1.06}

We have the final answer as

<h3>x = 16.55</h3>

Hope this helps you
