Answer :
6. x=28
7.x =6
8. x =9
9. x =9
Step-by-step explanation:
6.
(x+2)/10 = 3
Cross multiply
x+2 = 10 ×3
x+2 =30
Collect like terms and simplify
x =30-2
x = 28
7.
8x +9 -5x= 27
Collect like terms and simplify
8x-5x =27-9
3x =18
Divide both sides of the equation by 3
3x/3 = 18/3
x = 6
8.
10x+8=8x+26
Collect like terms
10x-8x=26-8
2x = 18
Divide both sides of the equation by 2
2x/2 = 18/2
x = 9
9.
2(x-5)+4x=x+35
Use 2 to open the bracket
2 × x =2x
2×(-5) =-10
2x-10+4x =x+35
Collect like terms and simplify
2x+4x-x = 35+10
5x = 45
Divide both sides of the equation by 5
5x/5 = 45/5
x =9

Answer: C. N </h3>
N stands for Newtons
In terms of SI units, 1 newton = 1 kg m/s^2
It's based off the equation F = ma, which is Newton's second law.

Extra info:
- Choice A is velocity
- Choice B is acceleration
- Choice D is some unit I don't really recognize, so I'm not sure if its nonsense or it may have some use. Though I'm sure that N/s isn't a measurement of force.
Answer:
r=-2/3 or r= 6
Step-by-step explanation:
To solve this equation to find r, first subtract 5 from both sides.
3r² - 16r -7 -5= 5 -5
3r² - 16r -12= 0 (simplify)
(3r + 2)(r - 6)= 0 (factorise the equation)
3r+2=0 or r-6=0
3r= -2 or r= 6
r= -2/3
