Difference between 17 and the square root of my mystery number
This is represented by:

is 5
Then:

What are two possible numbers that Hall could be thinking of?
We have to solve the equation, for x. So




The possible number that Hall could be thinking of is 144.
Answer:
Here
Step-by-step explanation:
We move all terms to the left:
7+9x-(6x-2)=0
We get rid of parentheses
9x-6x+2+7=0
We add all the numbers together, and all the variables
3x+9=0
We move all terms containing x to the left, all other terms to the right
3x=-9
x=-9/3
x=-3
Answer:
31.5 square feet of counter top
Step-by-step explanation:
x represents the number of square feet
40x + 750 = 2010 subtract 750 from both sides
40x = 1260 divide both sides by 40
x = 31.5
Supplementary angles add up to 180, so
6x+60+90 = 180 and solve for x
6x= 30
x=5
