Step-by-step explanation:
let x represent the bus
6x + 21 = 195
6x = 195 - 21
6x =174
x = 29
Answer:
x1 = -6, x2 = -2
Step-by-step explanation:
hope this helps :)
Answer:
x=-58/15
Step-by-step explanation:
distribute first 10-2.5x+12=21-10x-28
Simplify(add the numbers) 22-2.5x=-7-10x
move the variable to the left side 22-2.5x+10x=-7
move the constant to the right side -2.5x+10x=-7-22
simplify like terms 7.5x=-29
divide by 7.5 x=-58/15
alternate forms are x=-3 13/15 or x=-3.86
Look at the attachment
The line bisects the cord which we have to find
- Length of chord=12cm
- Half of the cord=12/2=6cm
- Radius=10cm
Its a right angle triangle
- using Pythagorean theorem
Distance of the chord from centre is 8cm.
