Answer:
just remove the parentheses and add the numbers
Step-by-step explanation:
Answer:
x=7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6(x−1)=−2x+50
(6)(x)+(6)(−1)=−2x+50(Distribute)
6x+−6=−2x+50
6x−6=−2x+50
Step 2: Add 2x to both sides.
6x−6+2x=−2x+50+2x
8x−6=50
Step 3: Add 6 to both sides.
8x−6+6=50+6
8x=56
Step 4: Divide both sides by 8.
8x
/8
=
56
/8
x=7
Perimeter (p) = length around a shape.
So any horizontal sides we can add based upon their length in x-values and any vertical sides we can add based upon their length in y-values. The diagonal sides we can find by the distance formula:

So the bottom base goes from x=1 to x=8, then up 1, right 1, and up from y=3 to y=9, then left from x=9 to x=6, down from y=9 to y=6, left from x=6 to x=3.
So far that is: (8-1)+1+1+(9-3)+(9-6)+(9-6)+(6-3)
= 7+2+6+3+3+3 = 24
Now for the diagonal:

P = 24 + 4.47 = 28.47
D) 28.472
Answer:
c=(ay-2)/m
Step-by-step explanation:
Isolate c
First I would multiply both sides by y
mc+2=ay
Then I would subtract 2
mc=ay-2
Then I can divide my m to get c alone
c=(ay-2)/m
What expression, in simplest form, shows the value of the new area of the poster?
10(17 - r) = (170 - 10r) square inches
What expression shows the value of the planned area of the card?
The planned area of the card is the difference between the initial area of poster and the new area of poster.
i.e. (10 x 17) - (170 - 10r) = 170 - 170 + 10r = 10r square inches.
