Maybe try this <span>2x+y=16
3x-y=4
------------
Add the two equations to solve for "x":
5x = 20
x = 4
--------
Substitute to solve for "y":
2*4 + y = 16
y = 8
----------
Solution: (4,8)</span>
4:3 > 8:6 > 12:9 > 16:12 > 20:15 > 24:18 the answer must be 24 seventh graders are there
Answer:
x = 73.3
y = 46.2
Step-by-step explanation:
Reference angle (θ) = 39°
Adjacent = 57
Hypotenuse = x
Opposite = y
Recall: SOHCAHTOA
✔️To find x, apply CAH:
Cos θ = Adjacent/Hypotenuse
Plug in the values
Cos 39° = 57/x
x × Cos 39° = 57
x = 57/Cos 39°
x = 73.3 (nearest tenth)
✔️To find x, apply TOA:
Tan θ = Opposite/Adjacent
Plug in the values
Tan 39° = y/57
57 × Tan 39° = y
y = 46.2 (nearest tenth)
The solution of a system of equations is the place where they cross; the point where both equations are true. find the place on your graph where your two lines intersect.
you should find (2, 3) as the intersection point. this is the solution for the system.
