Step-by-step explanation:
let the unknown be x
length = x
width = 3.6 cm
Perimeter = 2 lengths + 2 widths
48 cm = x + x + 3.6 + 3.6
48 cm = 2x + 7.2
40.8 = 2x
20.4 cm = x
if you wanna check,
perimeter = 20.4 + 20.4 + 3.6 + 3.6
48 cm = 48
Answer:
f(x) = 3.7x + 3
Step-by-step explanation:
Using the fact that y = f(x), then rearrange the equation making y the subject.
- 3.7x = 3 - y ( add y to both sides )
y - 3.7x = 3 ( add 3.7x to both sides )
y = 3.7x + 3 , that is
f(x) = 3.7x + 3
Answer:
The answer to your question is
Step-by-step explanation:
Data
Perimeter =32x - 12.8
Formula to calculate the perimeter of a square
Perimeter = 4 length of the side
Calculate the length of 1 side
4 length of the side = 32x - 12.8
length of the side = (32x -12.8) / 4
Simplification
length of the side = 8x - 3.2
Another way to represent the perimeter = 4(8x - 3.2)
See the picture below
Step-by-step explanation:
Let the ratio constant be 'x'
Sum of the ratios=3x+5x=8x
First person gets:-
3/8 x 560 = 210
Second person gets:-
5/8 x 560 = 350
10% of 1000 is 100. So 3% must be 30. $1000 + 30 = 1030. However, she adds the $50 in the account as well. So 1030 + 50 = $1080
