Answer:

C. 4x = 12

Step-by-step explanation:

You and three friends= you + 3 friends=4 people

Pizza= 12 pieces

Each person eats equal pieces of pizza

x= number of pieces each person ate

Equation

4x=12

Divide both sides by 4

x=12/4

=3

x=3

Therefore, each person ate 3 pieces of pizza each

Check:

4x=12

4(3)=12

12=12

aev [14]

Answer: d.3,500 + 0.06x > 4,000 + 0.04x

Step-by-step explanation:

Hi, to answer this question we have to write each inequality:

Jose earns a monthly salary of $3,500 plus a 6% commission on his sales, x.

So, his monthly earnings must be equal to the sum of the fixed monthly salary ($3500) plus the product of the number of sales (x) and the commission percentage in decimal form (divided by 100):

So:

Jose’s earnings: 3,500 + x (6/100)

Jose’s earnings: 3,500 + 0.06x

Maris earns a monthly salary of $4,000 plus a 4% commission on her sales.

So, her monthly earnings must be equal to the sum of the fixed monthly salary ($4000) plus the product of the number of sales (x) and the commission percentage in decimal form (divided by 100):

Maris’ earnings: 4000+ x (4/100)

Maris’ earnings: 4000+ 0.04 x

Since Jose's earnings must be greater than Maris' earnings

3,500 + 0.06x >4000+ 0.04 x

Determine the pattern in the table and write the function rule. <br> Please help asap.
klio [65]

you need to find how much the output changes for each unit change in the input. (ie from an input change from 5 to 6 the output changes by three units and an input change of 3 (2 - 5 )  units the output changes by 9 units). This will give you the gradient of the equation. then you have to find out the y intercept by finding what the output is when the input is 0. Do this by multiplying the input by the gradient and then subtracting it from that inputs output. This will give you the answer A) 3x

(Sorry, its a bit wordy :) )

Answer:

See explanation

Step-by-step explanation:

Given that 9 cups of macaroni requires 27 cups of water

Therefore, 1 cup of macaroni will require 27/9 = 3 cups of water

Now i can help you to work out the correct way of filling the table;

If 1 cup of macaroni requires 3 cups of water

x cups of macaroni will require 9 cups of water

x = 9 *1/3

x = 3 cups of macaroni

If 1 cup of macaroni requires 3 cups of water

x cups of macaroni will require 33cups of water

x = 33 *1/3

x = 11 cups of macaroni

If 1 cup of macaroni requires 3 cups of water

x cups of macaroni will require 21 cups of water

x = 21 *1/3

x = 7 cups of macaroni

If 1 cup of macaroni requires 3 cups of water

x cups of macaroni will require 27 cups of water

x = 27 *1/3

x = 9 cups of macaroni

Use this to tick the table.
