One side of triangle is 4 4 times the shortest side. The third side is 23 23 feet more than the shortest side. The perimeter is
jasenka [17]

Answer:

9, 32 and 36

Step-by-step explanation:

The perimeter of a triangle is the sum of all the sides.  Since you know the perimeter and the expressions for each of the sides, you can set up an equation to solve for the variable and find the values of the other sides:

one side: '4 times the shortest side' = 4s

shortest side: 's'

third side: '23 more than the shortest side' = s + 23

perimeter  = 77

Equation:  4s + s + (s + 23) = 77

Combine like terms:  6s + 23 = 77

Subtract 23 from both sides:  6s + 23 - 23 = 77 - 23 or 6s = 54

Divide by 6:  6s/6 = 54/6 or s = 9

one side: 4s = 4(9) = 36

shortest side: s = 9

third side: s + 23 = 9 + 23 = 32

A family went to a baseball game. The cost to park cars was $5 and the cost per ticket was $21. Write a linear function in the f
Sophie [7]

Answer:

The total cost y in dollars of going to the baseball game for x people of a family can be given as:

y=21x+5

Step-by-step explanation:

Given:

At a baseball game:

Cost of car parking = $5

Cost per ticket = $21

To write an equation in the form of y=mx+b representing the total cost of going to the baseball game.

Solution:

The total number of people in the family is = x

Using unitary method to find the cost of tickets for x persons.

If 1 ticket costs = $21

<em>Then, x tickets will cost in dollars</em><em> = </em>21x

Fixed rate for car parking = $5

Thus, the total cost y in dollars of going to the baseball game for x people of a family can be given as:

y=21x+5
