Answer: Width = 5 inches
Concept:
Here, we need to know the idea of the perimeter.
A perimeter is a path that encompasses/surrounds/outlines a shape.
Perimeter of rectangle = 2 (w + l)
w = width
l = length
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
w = w
l = 3w - 2
P = 36 inches
<u>Given formula</u>
P = 2 (w + l)
<u>Substitute the value into the formula</u>
36 = 2 (w + 3w - 2)
<u>Simplify values in the parentheses</u>
36 = 2 (4w -2)
<u>Divide 2 on both sides</u>
36 / 2 = 2 (4w - 2) / 2
18 = 4w - 2
<u>Add 2 on both sides</u>
18 + 2 = 4w - 2 + 2
20 = 4w
<u>Divide 4 on both sides</u>
20 / 4 = 4w / 4
w = 5

Answer:
80 yards
Step-by-step explanation:
Using the area formula, A = lw, set up an equation where w represents the width.
The length can be represented by 3w because it is 3 times the width:
A = lw
300 = (3w)(w)
300 = 3w²
Solve for w:
300 = 3w²
100 = w²
10 = w
So, the width is 10 yards.
The length will be 30 yards since the length is 3 times the width.
Then, add the lengths and widths together to find the perimeter:
10 + 10 + 30 + 30
= 80
So, the perimeter is 80 yards
Answer:
-3 / 2
Step-by-step explanation:
- 5x - 6 = 3x - 9
- 5x - 6 + 6 = 3 x - 9 + 6
- 5x = 3x - 3
- 5x - 3x = 3x - 3 - 3x
- 2x = - 3
- 2x / 2 = -3 / 2
- The X = -3 / 2
Company b because you dont need to give them 75 per month you would just need to give to more percent
Answer:
Lee has 19 nickels and 8 dimes
Step-by-step explanation:
hello, I think I can help you with this
Step 1
Let
value of a nickel=$0.05
value of a dime=$0.10
number of nickels=N
number of nickels=D
According to the question data Lee has $1.75 in dimes and nickels.
0.05N+0.1D=1.75,equation(1)
also, the number of nickels is 11 more than the number of dimes.mathematical speaking
N=11+D,equation(2)
Step 2
replace N from equation (2) into equation (1)
0.05N+0.1D=1.75
0.05(11+D)+0.1D=1.75
Now, solve for D
0.55+0.05D+0.1D=1.75
0.15D=1.75-0.55
D=1.2/0.15
D=8
Step 3
replace the value of D into equation(2) to obtain N
N=11+8
N=11+8
N=19
Hence, Lee has 19 nickels and 8 dimes
Have a great day.
