Please help. I need to know the strategy, the correct work, and to identify the error.
zysi [14]

Answer:

See below

Step-by-step explanation:

13x + 5 + 17x - 4.5 + x

NOTE: You can only add/subtract LIKE terms . Here we have  variable terms in x  (13x , 17x and x) and 2 constants ( 5 and 4.5).

Sarah's next line is

18x + 17x - 4.5 + x

This is incorrect . It looks like she  added 13x + 5 and got 18x!! Which is of course wrong because they are NOT LIKE terms. 5 is a constant and 13x is a variable term in x.

The third line is correct:-

35x - 4.5 + x.

She has added the 2 variables 17x and 18x.

Fourth line  is  30.5x + x. She's at it again - Trying to subtract 4.5 from 35x .

Last line 31.5x

She has added  the 2 terms in x correctly, but the final answer is wrong of course due to the earlier errors.

Using bangle side relationship theorem use the angle measures to list the side lengths of the triangle in order from longest to
scoray [572]

Answer:

AC= longest side

BC=middle side

AB=shortest side

Step-by-step explanation:

there is 180 degrees in a triangle, therefore

95+50=145

180-145=35

so we have angles 95, 50, 30

and we know that the side opposites with the angle corresponds to how big the side will be compared to the other sides

Therefore,

AC= longest side

BC=middle side

AB=shortest side

Three-quarters of a number is 15<br> work out four-fifths of the number
Anna11 [10]

Let the number be X

3/4 of X = 15


Multiplying out gives;

3X = 4x15

3X= 60

X = 20


Therefore, 4/5 of 20


Putting X = 20 we have;


4/5 x 20 = 16

Hope this help!
