<h3><u>The function used to find the perimeter of a square, represented by y, given the length of a side, represented by x is: y = 4x</u></h3>
<em><u>Solution:</u></em>
Let "y" be the perimeter of square
Let the length of side be "x"
From given,
The perimeter of a square is the product of four and the length of a side
Which means,
Substituting the given variables,
Thus perimeter of square is y = 4x
A+s=294
s=2a
Use substitution
a+2a=294
3a=294
a=98
Final answer: 98 adult tickets
If 1.5 and 2.5 are the height and base, then just use Pythagorean theorem,
Answer:
18 kg
Step-by-step explanation:
We can use a proportion.
First, 13 kg 500 g = 13 kg + 500 g = 13 kg + 0.5 kg = 13.5 kg
Proportion:
9 cows is to 13.5 kg as 12 cows is to x
9/13.5 = 12/x
Cross multiply.
9x = 13.5 * 12
Divide both sides by 3.
3x = 4.5 * 12
Divide both sides by 3.
x = 1.5 * 12
x = 18
Answer: 18 kg
4-0.5x=4-x
Add 0.5x for both side
4-0.5x+0.5x=4-x+0.5x
4=-0.5x+4
Subtract 4 for both side
4-4=-0.5x+4-4
0=-0.5x
Divide -0.5 for both side
0/-0.5=-0.5x/-0.5
0=x. As a result, x can not be negative in this problem. Hope it help!
