Two systems of equations are shown below:System A: 6x+y=2 -x-y=-3 System B: 2x-3y=-10 -x-y=-3 Which of the following statements is correct about the two system equations? A) The value of x for System B will be 4 less than the value of x for System A because the coefficient of x in the first equation of System B is 4 less than the coefficient of x in the first equation of System A. B) They will have the same solution because the first equations of both the systems have the same graph. C) They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 4 times the second equation of System A. D) The value of x for System A will be equal to the value of y for System B because the first equation of System B is obtained by adding -4 to the first equation of System A and the second equations are identical.

Four students spend $12 on school lunch at this rate find the amount 10 students will spend on the same school lunch

Answers

Answer:

10 students would spend $30.

Step-by-step explanation:

In order to find this, start by looking for the cost per student. We can do this by dividing the overall cost by the number of students.

$12/4 students = $3 per student.

Now we take that unit rate and multiply by the new number of students.

$3 * 10 students = $30 total spent.

You need 1 1/4 cups of sugar to make 20 cookies.To make 14 cookies, you will need how many cups of sugar?

Where do I begin and how do I solve this? Please help!

Answers

Following are the calculation of cups of sugar:

Given:

1 (1)/(4) cups sugar makes 20cookies

To find:

calculate cups of sugar in making 14 cookies.

Solution:

1 (1)/(4) cups sugar makes 20cookies

Which applies:

\to (5)/(4)cups sugar makes 20 cookies

For 14 cookies calculating the total cups:

Assuming the cups of sugar=x

then

\to x=(((5)/(4))* 14) / 20\n\n\to x=((70)/(4)) / 20\n\n\to x=( 17.5) / 20\n\n\to x=(17.5)/(20)\n\n\to x= 0.875

Therefore, the final answer is "0.875".
