For this case, the first thing we must do is define variables.
We have then:
x: number of blue beads
y: number of red beads
We now write the inequations system:
Answer: a system of linear inequations that represents the situation is:
The answer is A. Subtract the five on both sides and you end up with A :)
17/2 = 8.5 hours per week
8.5 x 5 = 42.5 hours in 5 weeks
Answer:
The expression that can be used is 0.80x
Step-by-step explanation:
Let
x ----> original price of an item
Remember that

That means---> the sale price is 80% of the original price
To find out the sale price, determine the 80% of the original price
----> percentage in decimal form
Multiply the original price by the percentage in decimal form to obtain the sale price
so

Answer:
Step-by-step explanation:
That would be 8 x 3. It would help because 24/8 = 3.
