Answer:
combine the two var. and you get 5y=11 so its 5.5 =y
Step-by-step explanation:
Answer:
85
Step-by-step explanation:
Write the numbers in order
66, 72, 74, 80, 83, 87, 91, 95, 98, 99
Find the middle number
83 and 87 are in the middle, so find the mean of them. 83+87= 170
170/2 = 85.
F - 1.47
The largest box represents 100 small cubes or 1. The four pillars represent 10 and there is four of them so it is 40. Then, the individual cubes are 7. So, 1.47.
Answer:
=> x° + 57° + (43°+24°) = 180° ------------ (angle sum property of ∆)
=> x° + 57° + 67° = 180°
=> x° + 124° = 180°
=> x° = 180° — 124°

=> x° = 56°</h2>

Step-by-step explanation:
so,

The coordinates of the final point after the two reflections is (-7, -4)
<h3>
How to reflect a point across an axis?</h3>
For a point (x, y), a reflection across the x-axis gives the point (x, -y), while for a point (x, y) a reflection across the y-axis gives (-x, y).
In this case, we have the point (7, 4), first we reflect across the x-axis, so we get the point (-7, 4).
Now we reflect across the y-axis, so the sign of the y-component changes, and we get (-7, -4)
So the coordinates of the final point after the two reflections is (-7, -4).
