HELP ASAP!! What is the equation for the constant of proportionality that matches the table?

Mathematics
1 answer:
valentinak56 [21]3 years ago
8 0

Answer:

The answer is y=1.5x

Step-by-step explanation:

When you do 4 x 3, that gets you 12, but on the table it says 6. You can get rid of that option.

When you do 4+2, it gets you 6. But when you do 6+2, it gets you 8. On the table it says 9. You can get rid of that option.

When you do 4 x 2, you get 8, but the table says 9. You can get rid of that option.

That then only leaves you with 1.5, which works with all of the values.

Jessica, Kareem, and Lamar served a total of 64 orders Monday at the school cafeteria. Jessica served 8 fewer orders than Lamar.
sergey [27]

Answer:

Jessica: 10 orders

Lamar: 18 orders

Kareem: 36 orders

Step-by-step explanation:

Let's first designate each person with a letter.

The number of orders served by Jessica can be designated as J

The number of orders served by Kareem can be designated as K

The number of orders served by Lamar can be designated as L

We know that they all served a total of 64 orders. This can be expressed as the sum of their orders equaling 64.

J+K+L=64

We also know that Jessica served 8 fewer orders than Lamar. This can be expressed as the number of orders served by Jessica, J, being equal to Lamar's orders L minus 8.

J = L-8

Fianlly, we know that Kareem served twice as many orders as Lamar. This can be expressed as the number of order's served by Kareem, K, being 2 times Lamar's orders L.

K = 2L

With these 2 equalities, we can substitute J and K in our original equation,

J+K+L=64

with their values expressed as a subtraction or multiplication of L.

J will be substituted with L-8, and K will be substituted with 2L.

J+K+L=64

With substitutions:

(L-8) + 2L + L = 64

We can simplify this by combining the L-terms:

L + 2L + L -8 = 64\\4L - 8 = 64

Next, we'll add 8 to both sides.

4L = 72

Divide both sides by 4:

L = 18

Thus, Lamar served 18 orders.

Using our expressions, we can find how many orders the others served.

Jessica:

J = L-8\\J = 18 -8\\J = 10

Jessica served 10 orders.

Kareem:

K = 2L\\K = 2*18\\K = 36

Kareem served 36 orders.
