Step-by-step explanation:
4x - 9 = 23
4x = 32
x = 8
the number is 8.
Step-by-step explanation:
step 1. when you graph 2 lines they must intersect unless they are parallel (same slope)
step 2. if they intersect then they have one point in common
step 3. that point in common solves both equations
step 4. when a point solves both equations it is called the solution.
Answer:
19.206
Step-by-step explanation:
First you need to find out 10% of 18.
You can do that by 18/100 which is .18.
Then multiply that by 10 which is 1.8 (10% of 18)
His hourly rate decreased by 3% AFTER his raise so you would find 3% of 19.8 and not 18.
You do the same process and divide 19.8/100
Then multiply this by 3 and you can get 0.594
That is how much his raise decreased by so you would subtract it from 19.8
19.8 - 0.594 = 19.206 (Round if needed)
Hope this helps
10.4% of 125 is 13 because 10.4%=.104 and .104x125 is 13
<span>A) x - y = 11
B) 2x +y =19
Multiplying equation A) by -2
A) -2x + 2y = -22 then we add it to B)
B) 2x + y = 19
3y = -3
y = -1
x = 10
