Answer:
m=8
Step-by-step explanation:
So use distributive property
which is
a(b+c)=ab+ac so
1/2(x+20)=1/2x+10
and the other
4(6-x)=24-4x
so now we have
1/2x+10=17/4x+24-4x
convert -4x to -16/4x and add to the 17/4x
1/2x+10=1/4x+24
subtract 24 from boths ides
1/2x-14=1/4x
multily both sides by 4
2x-56=x
subtract x from both sides
x-56=0
add 56 to both sides
x=56
Answer: y =
Step-by-step explanation: look for the lcm
a=
cross multiply
ax =9xy + 2
ax - 2 = 9xy
divide both sides by 9x

y=
Answer:30N
Step-by-step explanation:
Mass=5kg
Acceleration=6m/s^2
Force =mass x acceleration
Force =5 x 6
Force=30N
ASA for first 2 and same for other two
