Answer:
x > 23
Step-by-step explanation:
5x – 1 < 7x - 47
Add 1 to -47, you get -46.
5x < 7x - 46
Subtract 7x from 5x.
-2x < -46
Multiply both sides to reverse the inequality.
2x > 46
Divide both sides by 2.
x > 23

Answer:
you could stand at 5.0 ft and still be completely in the shadow of the tree
Step-by-step explanation:
From the diagram attached below;
We consider;
to be the height of the tree and
to be the height of how tall you could be and still be completely in the shadow of the tree.
∠D = ∠B = 90°
Also;
ΔEAD = ΔBAC (similar triangles)
Therefore, their sides will also be proportional
i.e



By cross multiply
225x = 45 × 25


x = 5.0 ft
Therefore, you could stand at 5.0 ft and still be completely in the shadow of the tree
