Answer:
The variable n represents the number of pencils that Yasmin has.
You can solve for n to determine how many pencils Yasmin has.
Answer: 2 7 0
Step-by-step explanation:
1. We assume, that the number 900 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 900 is 100%, so we can write it down as 900=100%.
4. We know, that x is 30% of the output value, so we can write it down as x=30%.
5. Now we have two simple equations:
1) 900=100%
2) x=30%
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:
900/x=100%/30%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 30% of 900
900/x=100/30
(900/x)*x=(100/30)*x - we multiply both sides of the equation by x
900=3.33333333333*x - we divide both sides of the equation by (3.33333333333) to get x
900/3.33333333333=x
270=x
x=270
now we have:
30% of 900=270
Answer:
Pretty sure it's the first one. It's the only one with the correct y-intercept and has a positive slope.
This is in fancy form, so you want to simplify it:
y = 3/4(x+4) - 6
Multiply it all,
y = 3/4x + 3/4(4) - 6
y = 3/4x + 3 - 6
y = 3/4x - 3
The first one matches.
Answer:
80 ounces
Step-by-step explanation:
If eight baseballs weigh 40 ounces, it means that there are 40 ounces in every eight baseballs.
40 ounces / 8 baseballs can be simplified to 5 ounces / 1 baseball.
So each baseball weighs 5 ounces.
If there were 16 baseballs, they would weigh 16 * 5 ounces.
16 * 5 = 80
16 baseballs weigh 80 ounces.
