The two numbers are 48 and 18.
66 = l + s
l = 2 + 3s
66 = 2 + 3s + s
66 = 2 + 4s
66 - 2 = 64
64 = 4s
64 / 4 = 16
66 = l + 16
66 - 16 = 50
50 - 2 = 48
16 + 2 = 18
66 = 48 + 18
Answer: 45 / 40 ft
Step-by-step explanation:
Given that She decides to change the width, the shorter side of the courtyard, from 45 ft to 40 ft. Which expression finds the change in the scale factor?
Actual width of shorter side = 45 ft
New width of shorter side = 40 ft
Scale factor is the ratio of the actual length to the new or intended length
Scale factor = Actual width / New width
Hence, scale factor :
45 ft / 40 ft

Answer:
The correct equation form for finding the price of a sandwich is 5x + 1.25 = 38.75 and the cost of each sandwich was $ 7.50
Step-by-step explanation:
1. Let's check all the information given for solving this question:
Cost of bag of chips = $ 1.25
Cost of sandwich = x
Cost of total order = $ 38.75
2. The formula for find the cost of sandwich (x) is this:
5x + 1.25 = 38.75 (Joaquin ordered 5 sandwiches and a bag of chips)
5x = 37.50 (Subtracting 1.25 at both sides)
5x/5 = 37.50/5 (Dividing by 5 at both sides)
x = 7.50
The cost of each sandwich was $ 7.50
Answer:
20 seconds
Step-by-step explanation:
The period is the value of t that makes the cosine argument change by 2π.
That value is ...
2π = π/10t
20 = t . . . . . . . multiply by 10/π
The period of the function is 20 seconds.
