<u>Answer:</u>

x = 14

<u>Step-by-step explanation:</u>

We are given that A, B and C are collinear points and B is in between A and C.

The length from A to B is 3 x, length from B to C is 2x - 7 and AC is 2 x + 35.

We are to find the value of x.

A B + B C = A C

3 x + 2 x - 7 = 2 x + 3 5

3 x + 2 x - 2 x = 3 5 + 7

3 x = 4 2

x = \frac { 4 2 } { 3 }

x = 14

Write the percent as a decimal and as a fraction.
Xelga [282]
<span>To write 215% as a decimal you can approach the problem two ways. You can divide 215 by 100. 215/100 = 2.15 You can also move the decimal two places to the left 215.0 = 2.15 To write 2.15 as a fraction you will place 215 over 100. {215/100}. You will then want to write this fraction in it’s simplest form. The greatest common denominator is 5 so you will then divide the numerator and denominator by 5. 215/5 = 43 100/5 = 20 215/100 = 43/20 To write this fraction as a mixed fraction you would divide 43 by 20. 43 ÷ 20 = 2 with a remainder of 3 This is written as: 2 3/20</span>
