1)
2)
3)
Step-by-step explanation:
So we know that the perimeter of the rectangle is 50.
The formula for the perimeter of a rectangle is given by:
Where l is the length and w is the width.
The length is (x+5) and the width is (x).
Thus, substitute (x+5) for l and (x) for w. Also substitute 50 for P. Therefore:
And that's our equation.
To solve, first distribute:
Combine like terms:
Subtract 10 from both sides:
Divide everything by 4:
So, the value of x is 10.
The length is the longer side. Thus, it is (x+5).
We now know that x is 10, substitute:
So, the length is 15 units.
Complete factorization of 28 gives an answer of 7 x 2 x 2. 7 on the other hand, has no other factor other than 7 and 1. The least common multiple of these numbers is the least number that can be divided by 28 and 7. The answer is 28.
Answer:
26 child tickets
Step-by-step explanation:
4c = a to make the adult tickets equal to the child tickets multiply the child tickets by 4. then use substitution.
6.10c + 9.90(4c) = 1188.20
6.10c +39.6c = 1188.20
45.7c = 1188.20
c = 26
