Answer:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
Step-by-step explanation:
First calculate the value of the 3 shirts as follows:
$ 71.83 - $ 7.99 = $ 63.84.
$ 63.84.
The general equation would be, where x is the value of shirt # 1, and the value of shirt # 2 and z is the value of shirt # 3:
x + y + z = 63.84, then for each shirt would be the following equations:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
For example, if we give values (always the sum of both under 63.84) to two shirts, x = $ 20, y = $ 30 then the value of shirt # 3 would be:
<em>z = 63.84 - 20 - 30 = $ 13.84</em>
Answer:
Step-by-step explanation:
Given: , which is an exponential growth function.
To evaluate: f(-3)
Substitute x=-3 in the given function, we get
Therefore, the value of .
Answer:
68.67
Step-by-step explanation:
Estimate 63% of 109
Change 63% to a decimal by locating the decimal which is after the 3 in 63 and move the two places to the left. So 63% as a decimal is .63
Now multiply .63 × 109
= 68.67
