Answer:
X=3, y=5
Step-by-step explanation:
3x + y = 14 equation 1
y=5 equation 2
3x + 5 = 14. substitute value of y from equation 2 into equation 1
3x=9
x-3
Answer:
23
Step-by-step explanation:
<h3> <u>Answer</u><u> </u><u>:</u></h3>
<h3><u>Explaination :</u></h3>
In the question it is given that the length is 4 cm more than the width so let us assume the width as x.
Therefore,
- Length (l) = 4 + x
- Breadth = x
As we know the formula of calculating the perimeter of rectangle is,
Here,
- P is perimeter
- l is length
- b is breadth
Putting their respective values,
=> 14 = 2 (x + 4 + x)
=> 14 = 2 × (x + 4 + x)
=> 14 = 2x + 8 + 2x
=> 14 = 4x + 8
=> 14 - 8 = 4x
=> 4x = 6
=> x = 6 / 4
=> x = 3 / 2
=> x = 1.5

Answer:
x = 8
Step-by-step explanation:
40 + 6x + 2 = 90 {Complementary angles}
Combine like terms
40+ 2 + 6x = 90
42 +6x = 90 {Subtract 42 form both sides}
6x = 90 - 42
6x = 48 {divide both sides by 6}
6x/6 = 48/6
x = 8
