Hello,
To solve this system of equations, we want to add or subtract the equations so that either x or y cancels out.
We can multiply the first equation by -2, so that 5y will become -10y, and then add the equation with the second so -10y and 10y will cancel out.
Multiplying the first equation by -2, we get:
-4x - 10y = -30
Add this to the second equation and we get:
x = 5
So, we have x = 5. However, we should plug it into both equations to solve for y and make sure both answers check out.
Doing this for the first equation, we have:
2(5) + 5y = 15
10 + 5y = 15
Subtract 10 from both sides to get:
5y = 5
Divide by 5 on both sides to get:
y = 1
We will now see if x = 5 and y = 1 works for the second equation.
5x + 10y = 35
5(5) + 10(1) = 35
35 = 35, checks out
So, x = 5 and y = 1.
Option choice B is correct.
Hope this helps!
Answer:
peeta is 30 and kat is 20 i think
Step-by-step explanation:
Answer: The correct answer is B.
The first thing to check is the sum of the angles. 32 + 51 + 97 = 180. Therefore, the sides equal 180 and we can have a triangle because all triangles have exactly 180 degrees.
Second, the number of triangles with these measures is endless. Imagine taking the initial triangle and doubling the size. The angles don't change but the triangle does. We could keep doubling the size forever.
Khaimook is answering lol
First you divide them all by 7 to see which are greater than 19
28/7=4
84/7=12
35/7=5
105/7=15
even if you add 1 to them they all are still less than 19
so select them all
hope this helps! :)
