How should you find x? X=

The value of  x is 9

Step-by-step explanation:

from the diagram it shows that it is a right-angled triangle.

so, the sum of angles in a right angled triangle is 90 degrees.

i.e 7x + 3x =90

10x=90

divide both sides by 10

x= 9

to check if your answer is correct, from 7x + 3x =90

we have,

7(9) + 3(9)= 90

63 + 27 =90

90=90

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
