Assuming this is a system of equations, here is how to find x.
2x + 3y = 45
x + y = 10
Multiply x + y = 10 by 2 so you are able to use the elimination method.
2x + 3y = 45
2x + 2y = 20
Subtract.
y = 25
Now that we've found y, we can plug it in to find x.
x + 25 = 10
Subtract 25 from both sides.
x = -15
1. Y=3/1+b
2. Y=-1/2+b
3. Y=-3/3+b
4. I can’t quiet remember how to do sorry :/

Step-by-step explanation:
1700 + 2029.8x = 9500
2029.8x=9500-1700
x=7800/2029.8
x=3.85
Answer:
B. 16.9
Step-by-step explanation:
Reverse Pythagoreans theorem C^2 - B^2 = A^2 so
7^2 - 5^2 = c^2 and it comes out to
49-25 = 24 the square root of that is 4.9 (rounded)
But we are lookign for the perimeter so
4.9 + 7 + 5 = 16.9
