17. Sample answer: the elevation is the product of the rate and the time
18. $227.50; sample answer: $45.50 ≈ $50, and $50 × 5 = $250,
which is close to $227.50.
Hope this helps! please consider marking my answer the brainliest :)
Plug 4x=9 in for y:
10x=18-2(4x+9)
10x=18-8x-18
10x=-8x
18x=0
x=0
now plug 0 in for x:
y=4(0)+9
y=9
to check, plug x and y back into one of the equations to make sure they are right:
10(0)=18-2(9)
0=18-2*9
0=18-18
0=0
Answer:
15
Step-by-step explanation:
If the line segment is IK, that means IJ+JK=IK. So, 7+8=15
It would be 90%..... 45/450= 10%.... so there would be 90% not being used.
