Answer: Add the equations to eliminate k
Step-by-step explanation:
Adding the equations, you get 2b=18, which you can solve for b. Afterward, you can substitute this value of b back into either equation to solve for k.

parallelogram area= base×height
288=base×12
base=24
To identify the rate of change (or unit rate) I would usually look for a pattern in the table or graph. For example, if I got a problem like what is the unit rate for price per pound of potatoes and they gave me a chart like this:
Price. Potatoes
1. 3
2. 6
3. 9
I could determine that the unit rate (or rate of change) would be that for every $1 you could get 3 potatoes
I hope this helped! Have a wonderful day! :-)
What we know: one part of candy costs $6 per kg
another part of candy costs $4.50 per kg
To get a 15kg candy, lets add 6 and 4.5
6+4.5=10.5
Add 4.5 to 10.5
4.5+10.5=15
So, We need 2 kg of the $4.50 candy, and 1 kg of the $6.00 candy.
Hello!
x + 3y = 2
Rewritten into slope form: y = mx + b
Find the slope when rewritten:
Move x to the right hand side of the equation. (Subtract)
x - x + 3y = 2 - x
3y = 2 - x
Divide both sides by 3:
y = 2/3 - 1/3x
Rearrange:
y = -1/3x + 2/3.
The slope is equivalent to -1/3.
