Answer:
one solution
Step-by-step explanation:
here, we want to select the correct option
From the system, we have two values of y
Equating the y-values
3x + 2 = -2x - 1
What this mean is that there is only a particular point where this solution will work and as such, the system has one solution
Answer:
Units of hair products = 2634 units
Step-by-step explanation:
Given that:
Worth of products in the inventory = $6400
Average cost per unit = $2.43
Number of units = 
Number of units = 
Number of units = 2633.73
Rounding off to nearest whole number = 2634 units
Hence,
Units of hair products = 2634 units
1. We assume, that the number 3000 is 100% - because it's the output value of the task.
<span>2. We assume, that x is the value we are looking for. </span>
<span>3. If 100% equals 3000, so we can write it down as 100%=3000. </span>
<span>4. We know, that x% equals 600 of the output value, so we can write it down as x%=600. </span>
5. Now we have two simple equations:
1) 100%=3000
2) x%=600
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=3000/600
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 600 is what percent of 3000
100%/x%=3000/600
<span>(100/x)*x=(3000/600)*x - </span>we multiply both sides of the equation by x
<span>100=5*x - </span>we divide both sides of the equation by (5) to get x
<span>100/5=x </span>
<span>20=x </span>
<span>x=20
So 600 is 20% of 3000</span>
Answer:
Pedro spent 9 weeks with his uncle and his friend.
Step-by-step explanation:
First, you need to find the amount of weeks Pedro spent with his friend. The statement indicates that he spent two weeks more with his friend than with his uncle which means that you have to add the number of weeks he spent with his uncle plus 2, which you can show in a number line:
2
___________________
1 2 3 4 5 6 7 8 9 10

Now, you can find the and answer by adding up the number of weeks he spent with his uncle plus the weeks he spent with his friend:

__________________________________
1 2 3 4 5 6 7 8 9 10

According to this, the answer is that Pedro spent 9 weeks with his uncle and his friend.
