-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!! :)

A rectangle has a width of 2/7 cm and a length represented by the expression a+4. Find the area. (tell me how btw! and i will give brainliest.)
Answers
answer:
we know the formula for area is,
L x W
so,
2/7 (a+4) = area
solve this by distributing the 2/7,
you get = 2/7a + 8/7
the area is 2/7a + 8/7
if correct, please mark the brainliest :)

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

[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^2So 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.

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%
