Answer:
The solution to the system would be (3, -1)
Step-by-step explanation:
You can find the solution to this system by using the elimination method. To do that, start by multiplying the top equation by -5 and then adding it through.
-5x + 20y = -35
5x + 9y = 6
-----------------
29y = -29
y = -1
Now that we have the value of y, we can plug it into either equation and find the x value.
x - 4y = 7
x - 4(-1) = 7
x + 4 = 7
x = 3
Answer:
Exact form: 23/12
Decimal form: 1.916 repeating
Mixed number form: 1_11/12
Step-by-step explanation:
Turn 2_1/4 into fraction
(2 x 4) = 8 + 1 = 9
9/4 - 1/3 = 23/12
Answer:
Hey there!
A pie graph is best used for looking at the percentages in each category.
Let me know if this helps :)
So it's - 19/9 - (-13/3) therefore -19/9 + 13/3.
So it needs to have a common denominator so it would be 39/9 instead of 13/3.
Therefore the answer is 20/9 or 2 2/9
