Answer:

h = 10.018 ≈ 10 m

Step-by-step explanation:

Because this triangle is right, there are two ways to get base*height (the area); the two legs, or the hypotenuse and the altitude it is connected to. And those areas will be equal.

Therefore, 12 m * 18.2 m = 21.8 m * h.

Multiply: 218.4 = 21.8h

Divide: h = 10.018 ≈ 10 m

12x - 5 = 8x - x + 50 Help please show work and check the solution

Inga [223]

Answer:

x = 11

Step-by-step explanation:

$12x - 5 = 8x - x + 50 \\ 12x - 5 = 7x + 50 \\ 12x - 5 - 7x = 7x + 50 - 7x \\ 12x - 7x - 5 = 50 \\ 5x - 5 = 50 \\ 5x - 5 + 5 = 50 + 5 \\ 5x = 55 \\ x = 11$

and check:

$12(11) - 5 = 8(11) - (11) + 50 \\ 132 - 5 = 77 + 50 \\ 127 = 127$

6y-4=4y+2

2y=6, so y=3.

Plugging it in, you get that AC equals 4*3+2=14.

This is an isosceles triangle.

You have THREE fifths of material.

You use ONE of those fifths.

That leaves you with TWO fifths.

I believe the answer to this is "If they babysit for 5 hours, Jayna will earn more" because Hannah charages 7$ an hour and Jayna charges 10$ an hour so Jayna will have more money than Hannah in five hours.
