Step-by-step explanation:
Add them together and then divide
No problem!
Okay you must set and equation.
$40 × ? = 10
I used multiplication because when things are discounted, they are multiplied by decimals
? =


is equal to

1/4 is 25%
The item needs to be marked down 25% to buy and get a discount of $10
Answer:
The equation would be:
y= 4,000(x-1)+20,000
y= annual income
x= number of years
With this you can find the points for the scatter plot:
x=1 y= 20,000
x=2 y= 24,000
x=3 y= 28,000
x=4 y= 32,000
x=5 y= 36,000
x=6 y= 40,000
x=7 y= 44,000
x=8 y= 48,000
The scatter plot that represents this situation is attached.
Your answer is 6.643 kg
Because 1 gram is equal to 0.001 kilograms, 0.001 kg x 6,643 g = 6.643 kg
Hope this helps!
x-2=7
apply additon property of equality
x-2+2=7+2
x=9
