Hello here is a solution :
Answer:
x=6
Step-by-step explanation:
2(x-4)+x=10
expand into 3x-8
add 8 to both sides 3x-8+8=10+8
simplify 3x=18
divide both sides by 3 3x/3=18/3
simplify x=6
Answer:
x=24
Step-by-step explanation:
Step 1: Add 3 to both sides: 1/2x-3+3=9+3
Simplify that: 1/2x=12
Step 2: Multiply both sides by 2: 1/2x*2=2*12
Simplify: x=24
Hope this helped! :)
-10=10(k-9)
so,
-10=10k-90
that is just expanding the brackets by multiplying to k and-9
then.
-10=10k-90
move the-90 over by adding 90
so, 80=10k
k =80/10
k=8
An example of a unit rate would be driving a car at 50 miles per hour. 50 miles per every 1 hour is a unit rate.
