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.
The answer is 28
bc 3+(5x5) = 3+25 and 3+25 is 28
Answer:
x = 8
Step-by-step explanation:
Δ RST is equiangular since all 3 sides are congruent, thus
Each angle in the triangle is 60° , then
7x + 4 = 60 ( subtract 4 from both sides )
7x = 56 ( divide both sides by 7 )
x = 8
Answer:
Subtract 2.5 after every term.
Step-by-step explanation:
13-2.5=10.5
10.5-2.5=8
So on and so forth. Therefore, the rule is subtracting 2.5 after every term.
