in order to solve these equations, you need to divide the number by the varible. so #5 is 2.5y=5. you would divide 5 by 2.5, to get 2. the answer would be y=2
Answer:
Full question attached below.
Yes, the system of equations on line 4 has the same solution set as the system of equations on line 1
Step-by-step explanation:
There is no difference between the systems of line 1 and 4
1st system
5x + 3y = 14
4x - 2y = -2
4th system
10x + 6y = 28
12x - 6y = -6
In the fourth system, we factor number 2 from the first line, and number 3 from the second line
4th system
2[5x + 3y] = 2[14]
3[4x - 2y] = 3[-2]
If we simplify,
4th system
[5x + 3y] = [14]
[4x - 2y] = [-2]
We get the same system as the 1st
Therefore, the solution is the same.
Answer:
Well, in order o figure this out, you have to understand the definition or range.
Range is the difference between the lowest and highest values.
Since 78 use to be the highest number, the range was 55
Now when we remove the outlier, the new highest value is 45, decreasing the range to 22.
Hope this helps!
Answer:
20 pizzas
Step-by-step explanation:
100% of the pizzas were made with extra cheese.
20 pizzas had extra cheese
100% of 20 = 20
So... 20 pizzas
