W=x
L=2x+17
Double everything since we need to lengths and two widths to find the perimeter
2x+17+2x+17+x+x = 76
Combine like terms
6x+34=76
Solve for x
First step is subtract 34 from both sides
6x=42
Next you divide both sides by 6 in order to get x by itself
X=7
Now you plug in 7 into the x’s in length and width
W=7 cm
L=31 cm
THE WIDTH IS 31 CM
Check:
7+7+31+31 = 76 cm
It equals 76 cm just like the problem said so therefore it is right.
Answer:
We can just work backwards to find the value of x.
If 3 * x = 23,
then x = 23 / 3
and 23 / 3 = 7.6 reoccurring.
Step-by-step explanation:
Hope this helps:)
You can subtract 7t from both sides of the equation. This gives
... 7t -7t +3 = 8 +7t -7t
... 3 = 8 . . . . . an obvious FALSE mathematical statement
There is no value of t that will make this statement true.
The given equation has NO SOLUTION.
Answer:
x=11/3
Step-by-step explanation:
x-4+3x=8-2x+10
4x-4=18-2x
6x=22
x=22/6
