Answer:
$40 / x ; $10 / y
Step-by-step explanation:
1.)
For the question, the number of girls aren't given ;
Assume the number of girls = x
The total amount they agreed to spend between themselves = $40
Amount spent on average :
Total amout to be spent / number of girls
Amount spent on average by each girl = $40 / x
2.)
The cost of ice cream isnt given;
Assume, cost per ice cream $y
Amount to be spent on on ice-cream = $10
Number of ice creams that can be purchased :
Amount to be spent on ice-cream / cost per ice cream
$10 / y
Answer:
D
Step-by-step explanation:
Since 1 and c are supposed to be equal, I put 2.35+0.25x=1.75+0.4x and solved that for the x. I got 4. Then, since I want to find the price of the beef, I plugged the 4 in the equation of "b" and got 3.35.
I made many mistakes when solving so I restarted many times which is why it took so long to answer. Whew, I actually found the answer though!
If you want to help, mark me brainliest, I'm only 1 away from getting virtuoso! That would make my day, and hope I made yours.
Bye!
We are going to solve for x=-2, y=2/3x+3, y=2/3(-2)+3, y=5/3. Therefore, x=-2 and y=5/3
Answer:
y = 9 + 19x
Step-by-step explanation:
To find the equation matching a set of data, you simply try a few values for x and see if by solving that side of the equation you get the value of y. If you do, you found your equation.
You have a big advantage here... since you have the value of y when x = 0.
When x = 0, y = 9, that's a very important data to have to simplify your research.
Let's try the value of 0 for x in each of the given equations:
y = 18 + 10 (0) = 18 --- NO
y = 9 + 19 (0) = 9 --- YES! We can confirm with another value of x:
y = 9 + 19 (1) = 28 --- YES! Confirmed!
y = 9 + 19x is your answer!
