Tayna bought 3 items that all share the same price.
So, we will call this 3x. Where x = a price.
Then Tony bought 4 items that each cost the same amount, but each was $2.25 less than the items that Tanya bought. So, we will call this 4(x - 2.55).
We put parentheses around the x and 2.55 because x = the price and Tony's items all are $2.55 less than Tanya's.
Now lets put the equation together and solve this.
3x = 4(x - 2.55)
It has an equal sign because both paid the same amount of money.
Let's do the distributive law of property with the 4.
3x = 4x - 10.2
-x = -10.2
Transpose the 4x.
Because both are negative, it's actually positive.
x = 10.2
Now let's substitute the x in the equation to see if it fits!
3(10.2) = 4(10.2 - 2.55)
After doing the work it comes out as 36=36.
But now back to the original question. What is the individual price for each person?
We know that Tayna's price for each item is $10.2. But what about Tony's?
Well in the question it said it's $2.55 less than Tayna's items.
$10.2 - $2.55 = $7.65
So, each of Tony's items is $7.65.
Length / wingspan
14.8 / 9.8 = 0.5 / x
cross multiply
(14.8)(x) = (9.8)(0.5)
14.8x = 4.9
x = 4.9 / 14.8
x = 0.331 meters....wingspan of model
Answer:
1. $18.90
2. Every statement is true EXCEPT e
Step-by-step explanation:
For number 1. We first need to find how much one ticket costs. To find this we divide profit by number of tickets sold. So,
13.50/15 = $0.90
So to find the cost of 21 tickets we times the cost per ticket by 21
21 x 0.90 = 18.9
So $18.90
2.
They sold 6 cases in 40 minutes.
6/40 = 0.15
They sell 0.15 cases per minute
For a we wanna see if they can sell 27 cases in 180 minutes so
0.15 x 180 = 27
So a is true
B)
0.15 x 80 = 12
So b is true
C)
0.15 x 120 = 18
C is true
D)
0.15 x 160 = 24
D is true
E)
0.15 x 200 = 30
E is false
Answer:
The number is 74.
Step-by-step explanation:
15+()=42
42-15 = (x+7)/3
27(3) = x+7
81 - 7 = x
x = 74
