Answer:
0.0714285metres, 0.07 metres
Step-by-step explanation:
100÷7 = 14.285...
5x14.285..=71.4285...
1/10 x 71.4285cm =7.142, 0.07metres
Cos 28 = 18/ y
so
y = 18 / cos 28
y = 18 /.8829
y = 20.4
Answer:
If you need the equation: 10x - 12
If you need the equation more simplified: x - 1.2
Step-by-step explanation:
(2x + 7) - (8x + 5)
Move the parts of the equation around
(2x + 8x) - (7 + 5)
Add 2x and 8x together
10x - (7 + 5)
Add 7 and 5 together
10x - 12
If you need it even more simplified, continue
10x - 12
Divide by 10
x - 12/10
Simplify
x - 1.2
