Solve by elimination by filling in the blanks below.
We will cancel our x's in this problem!

-5x+4y=30

2x+3y=-12

Answers

Answer: (x, y)=(0, -6)

Step-by-step explanation:

To solve a system of equations there are usually 3 general ways.

- Elimination

- Substitution

- Augmented Matrix

Since the question is asked to use elimination, we are going to use it.

--------------------------------------------------------------------------------------

-5x+4y=30

2x+3y=-12

-10x+8y=60

10x+15y=-60

23y=0

y=0

------------------------------------------------------------------------------------------

Substitute the y value into any one of the equations

2x+3y=-12

2x+3(0)=-12

2x+0=-12

x=-6

Hope this helps!! :)

At the county fair, 210 snow cones were sold for a total of $540. Large snow cones (x) cost $3.00 each and small snow cones (y) cost $2.00 each. Which equations below could be used to model this system of equations? Select all that apply.

Answers

Answer:

3x + 2y = 540

x + y = 210

Step-by-step explanation:

Giving the following information:

At the county fair, 210 snow cones were sold for a total of $540. Large snow cones (x) cost $3.00 each and small snow cones (y) cost $2.00 each.

We can establish the following system of equations:

x= number of large snow cones sold

y= number of small snow cones sold

3*x + 2*y = 540

x + y = 210

Alice's average mark for 4 Science exams is 68%. Can Alice score enough marks in a fifth exam so that her average mark increases to 75?%? Give reasons.

Answers

Answer:

It is not possible for Alice to score an average of 75% because what she needs to score in the fifth exam exceeds the maximum possible score.

Step-by-step explanation:

She scored an average 68% in all 4 exams.

This means; (68% + 68% + 68% + 68%)/4

Now, a fifth exam is added and we want to know if her average can now be 75%.

Thus, let the score in the 5th exam be x and we now have;

(68% + 68% + 68% + 68% + x)/5 = 75%

Multiply both sides by 5 to get;

(68% + 68% + 68% + 68% + x) = 375%

272% + x = 375%

x = 375% - 272%

x = 103%

The maximum score is 100% and therefore it is impossible for her to score 103%. Therefore it is not possible for Alice to score an average of 75%

[tex](1/5k)^2=1/5^2*k^2[/tex]

[tex]1/25*k^2=\frac{k^2}{25}[/tex]

Answer:  [tex]\frac{1}{25}k^2[/tex]

This is equivalent to [tex]\frac{k^2}{25}[/tex]

In decimal form, this is equivalent to 0.04k^2

==================================

Work Shown:

We have the two pieces 1/5 and k, all in the parenthesis being squared.

Square each piece

Squaring the piece 1/5 leads to (1/5)^2 = 1/25, since 5^2 = 25squaring the k value leads to k^2

So overall, we end up with the answer [tex]\frac{1}{25}k^2[/tex] which is equivalent to saying [tex]\frac{k^2}{25}[/tex]

In decimal form, this is 0.04k^2 because 1/25 = 0.04

If a triangle has two sides that are 17 meters & 4 meters.

What statement below best describes the range of values

the 3rd side could be?

Smaller than 20 meters

O Larger than 13 meters

Between 13 meters & 21 meters

Larger than 21 meters

Answers

Answer:

Between 13 meters & 21 meters

Step-by-step explanation:

Sum of two sides of a triangle must be greater than the third side and difference of two sides must be less than the third side.

Sum of two sides [tex]=17+4=21[/tex] meters

Difference of two sides [tex]=17-4=13[/tex] metres

Therefore,

[tex]13<[/tex] third side [tex]<21[/tex]

Option: Between 13 meters & 21 meters is correct.
