Answer:
x = -1 y = -1
Step-by-step explanation:
x + 3y = −4
x + 5y = −6
Multiply the first equation by -1
-x - 3y = 4
The add to the second equation to eliminate x
-x - 3y = 4
x + 5y = −6
--------------------
2y = -2
Divide by 2
2y/2 = -2/2
y = -1
Now solve for x
x+3y = -4
x +3(-1) = -4
x -3 = -4
Add 3 to each side
x-3+3 = -4+3
x = -1
Answer:
c = 3/5
Step-by-step explanation:
5c+16.5=13.5+10c
Subtract 5c from each side
5c-5c+16.5=13.5+10c-5c
16.5 = 13.5 +5c
Subtract 13.5 from each side
16.5 -13.5 =13.5-13.5 +5c
3 = 5c
Divide by 5
3/5 = 5c/5
3/5 =c
Answer:
hypotenuse = 25 yards
Step-by-step explanation:
Use pythagorean theorem
c^2 = a^2 + b^2 where c = hypotenuse and 'a' and 'b' are the legs
hyp^2 = 24^2 + 7^2
hyp^2 = 625
hyp = 25 yd
Probably true
you can test it too
