Answer:
x = 5, y = 4
Step-by-step explanation:
Solve for one variable. x will be simpler using the second equation.
3x = 15
Divide by 3.
x = 5.
Now put that into the other equation.
4x + 5y = 40
Substitute variable.
4(5) + 5y = 40
20 + 5y = 40
Subtract 20 from both sides.
5y = 20
Divide by 5.
y = 4.

Answer:
4.25 hours
Step-by-step explanation:
A fully charged phone would be at 100%, so we'll set y equal to 100 and solve for x:
100=20x+15
85=20x
4.25=x
So Sammi's phone will be fully charged in 4.25 hours.
Answer:
4.25 hours
Step-by-step explanation:
"Fully charged" means the percentage should be 100%.
Substitute 100 for y then solve for x.
[tex]100=20x+15\\85=20x\\x=\frac{85}{20}\\x=4.25 \text{ hours}[/tex]

Step-by-step explanation:
1. 100 = 100%, so seeing that there are 55 boys and 45 girls, we can go ahead and turn those into percentages, making this answer correct.
2. Once again, 100 = 100%, so 17 = 17%
3. "10/55 of those" isn't implying this is the boys only, but rather everyone, so this statement is not correct.
4. 10/35 of the students who chose math are girls. We can see that on the graph.
5. 8 + 8 = 16. Those are both the same number and half and half of the boys and girls...

Answers
Answer:
$45000
Step-by-step explanation:
Given data
Net income =$50,400
Let the prior year income be x
12/100*x +x= 50400
0.12x+x= 50400
1.12x= 50400
x= 50400/1.12
x= $45000
Hence the prior year income is $45000

Answers
Answer:

Step-by-step explanation:
The dot plot provided is almost symmetric :
Obtaining the median value :
2, 3, 5, 5, 6, 6, 6, 6, 7, 7, 7, 9
1/2 ( n + 1)
n = 12
1/2 (13) = 6.5
(6 + 6) /2
12 /2
= 6
Counting the number of points to the left and to the right of the median vlaue in the plot, we'll see that the difference in values aren't entirely different, and as such folding along the median value won't leave too much on one side than the other. Hence, the plot is symmetric.
