6.3=0.9y ....6.3/0.9=7.......y=7
x+7.72=19....19 - 7.72= 11.28.......x=11.28

Solve y: 6.3 = 0.9y
6.3/0.9 = 0.9y/09
y = 7

Solve x: x + 7.72 = 19
x + 7.72-7.72 = 19 - 7.72
x = 11.28

What is y? 7 What is x? 11.28

Simplify 24:30:12.<br> show working out and answer please

Naily [24]

First, you find the biggest number that you can divide 24, 30, and 12 by. I would go with 6, because it will simplify all the numbers into the simplest forms possible in this equation. Then, divide each number by 6.
24/6= 4
30/6= 5
12/6= 2

The answer:
4 : 5 : 2

Hope I could be of help:)

Marysya12 [62]

$\tan( \alpha ) \: = \: \frac{h}{b}$
$\alpha \: = \: {22}^{0}$
$h \: = \: 450 \: ft$
Therefore,
$b \: = \: h \cot( \alpha )$
$b \: = \: 450 \: ft \: \times \: \cot( {22}^{0} )$
b = 450 ft × 2.47508685
b = 1,113.78908 ft
or,
b ≈ 1,114 ft.
