5(x-2)+7=65-4(5x-8)
We move all terms to the left:
5(x-2)+7-(65-4(5x-8))=0
We multiply parentheses
5x-(65-4(5x-8))-10+7=0
We calculate terms in parentheses: -(65-4(5x-8)), so:
65-4(5x-8)
determiningTheFunctionDomain
-4(5x-8)+65
We multiply parentheses
-20x+32+65
We add all the numbers together, and all the variables
-20x+97
Back to the equation:
-(-20x+97)
We add all the numbers together, and all the variables
5x-(-20x+97)-3=0
We get rid of parentheses
5x+20x-97-3=0
We add all the numbers together, and all the variables
25x-100=0
We move all terms containing x to the left, all other terms to the right
25x=100
x=100/25
x=4
Answer:
x = 14
Step-by-step explanation:
4x + x + 90 = 160
5x + 90 = 160
- 90 -90
<u>5x</u> = <u>70</u>
5 5
x = 14
Hope this helps!
Answer:
11
Step-by-step explanation:
the formula for the area of a triangle is base times height divide by two. 22 is half of 44 so the base would have to be 11.
11 (base) times 4 (height) equals 44 divide by 2 equals final answer of 11
700 is 100 times bigger than 7
