Multiply numerator and denominator by
Things should simplify pretty nicely.
Answer:
The relationship between the cost/mass is $2.25/kg.
Step-by-step explanation:
You first need to divide $4.50 / 2, to know what a single kilogram mass costs.
$4.50 / 2 = $2.25
Now that you have this unit rate $2.25, You can multiply/add it.
$4.50 + $2.25 is $6.75, + another $2.25 = $9.00, and so on.
Answer:
72
Step-by-step explanation:
You can use the 9s trick
BC because it is across from the largest angle :)
This system of equation has an infinite number of solutions.
You can tell this because multiplying one equation by a constant gives you exactly the other equation. You can multiply the second equation by 3.
9x - 6y = 15
5(3x - 2y = 5) = 9x - 6y = 15
When this happens, you can assume that there are an infinite number of solutions.
