Answer:
8.1
Step-by-step explanation:
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.
Answer:
13
Step-by-step explanation:
-5 x 2 - 8x + 1
= -5 x 2 - 8(3) + 1
= -10 - (-23)
= 13
Answer:
look at the photo I have sent
you wearing a mask right now???
One dozen = 12
3 dozens = 12*3 or 36
To make 36 cookies you need 4 eggs and 1/2cups of chocolate chips.
Ben wants to make 12 dozen or 144 cookies.
144/36 = 4
To find out how many chocolate chips and eggs he needs we can multiply the amount of chocolate chips and eggs it takes to make 3 dozen by 4 to find out how many chocolate chips and eggs he needs to make 12 dozen.
4 *4= 16 He will need 16 eggs
4*1/2= 2 He will need 2 Cups of chocolate chips.
