3x + 4y = 32....multiply by 5
5x + 5y = 50...multiply by -3
---------------
15x + 20y = 160 (result of multiplying by 5)
-15x - 15y = -150 (result of multiplying by -3)
--------------add
5y = 10
y = 10/5
y = 2
3x + 4y = 32
3x + 4(2) = 32
3x + 8 = 32
3x = 32 - 8
3x = 24
x = 24/3
x = 8
solution (8,2)
The students conclusion is incorrect......it is answer choice 1
<span>q =r/2(s+t) for t
</span><span>2q =r(s+t)
2q = rs + rt
rt = 2q - rs
t = 2q/r - s
hope it helps</span>
Answer:
Last one, triangles AOB and COD
Step-by-step explanation:
In step 3, they are talking about the side/angle/side postulate. That helps in describing a triangle, therefore she must be talking about a triangle
