That would be 3.5 b/c it can’t be expressed as a ratio or a simple fraction
Answer:
X=9
Step-by-step explanation:
perimeter =2L+2B
6= 2(x-6)+2(x-9)
6= 2x- 12+2x- 18
6= 4x-30
4x=30 + 6
4x=36
divide both sides by 4
x= 9

Answer:
£6/h
Step-by-step explanation:
Molly is paid £280 for 35 hours' work, so
£280/(35 h) = £8/h
In the next 5 hours, her pay jumps to £350, so she earns at a rate of ...
(£350 -280)/(5 h) = £70/(5 h) = £14/h
The difference in her pay rates is £14/h -£8/h = £6 per hour.
Answer: C , triangles reflected across the line Y=X
Explanation: The line Y=X intersects through the origin and has a slope of positive 1, so if you imagine that line on the graph shown, you're able to see how the triangles are reflected across it.
Also, when the X and Y coordinates are "flipped" for each triangle, you can tell that it's reflected across Y=X. For example, the point at the right angle for the red triangle is (1,-1), while the corresponding point on the black triangle is at (-1,1), "flipping" the coordinates.
Hope this helps!!! :)
