So you reversed the subtraction a bit; the equation you're gonna be solving is
.
First step ya gonna do is to reverse the + and - symbols in the trinomial thats in the parentheses so your equation looks like
Now just combine like terms and your answer should be
Solve for y, add 8x to the other side then when y is isolated divide both sides of the question by two and that should give you your final equation and you should have the slope and yint
Answer:
- story 1- B and story 2-A
- x and y is the amount of flyers she gave to each volunteer.
- 3x+12=90 3y+36=90
- x= 26 y=18
3x+12=90
3x+12-12=90-12
3x=78
3x/3=78/3
x=26
3y+36=90
3y+36-36=90-36
3y=54
3y/3=54/3
y=18
I hope this is good enough:
Let this number be x.
"Six less than seven times a number is equal to -20" can be represented by the equation 7x - 6 = -20. We need to solve for x.
First, add 6 from each side so we can have the variables on a side and the numbers on the other:
7x - 6 + 6 = -20 + 6
7x = -14
Then, you divide each side by 7 so we can get the variable x alone on a side, and its value on the other side:
(7x)/7 = -14/7
x = -2
You can re-check your answer (very important):
7x - 6 = 7 (-2) - 6 = -14-6 = -20
The answer has been approved.
Hope this Helps! :)
Step-by-step explanation:
perimeter=28
length=2x
width=x
28=2(x+2x)
28=2x+4x
28=6x
28/6=6x/6
4.67=x
width=4.67
length=2×4.67
=9.34
