Answer:
Each piece weighed 1/10 of a pound.
Step-by-step explanation:
We have 3/5 of a pound and we want to divide it by 6 equal pieces for each student. 6 equal pieces is the same as 6/1.
In order to divide 3/5 by 6/1 we need to invert the 6/1 and multiply. So, it becomes 3/5 x 1/6. First, we multiply the numerators: 3x1=3 then we multiply the denominators: 5x6=30. The result is 3/30, which can be reduced by dividing both the numerator and denominator by 3. 3/3=1 and 30/3=10. So, the result is 1/10.
The volume of a gas V held at a constant temperature in a closed container varies inversely with its pressure P. If the volume of a gas is 1350 cubic centimeters when the pressure is 250 millimeters of mercury (mm Hg), find the volume when the pressure is 450mm Hg.

QUESTION: find the perimeter
Answer:
4g + 4
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Length = 0.7g + 2
Width = 1.3g
Plug in the values into the equation
Perimeter = 2(0.7g + 2 + 1.3g)
Perimeter = 2(0.7g + 1.3g + 2)
Perimeter = 2(2g + 2)
= 2*2g + 2*2
Perimeter = 4g + 4

Step-by-step explanation:
Look at the pic...
Answer:
4x + 2y
Step-by-step explanation:
1. 4x - 3(x - 2y) + 1/2(6x - 8y)
4x - 3x + 6y + 3x - 4y
4x + 2y
2. 4x - 3(x - 2y) + (1/2)(6x - 8y) =
4x - 3x + 6y + 3x - 4y =
4x + y(6 - 4) = 4x + 2y = 2(2x + y)

SAT QUESTION!!!
Jayden has been reading a 275-page book for English class. On average, he has read about 10 pages in 15 minutes. With a deadline looming, Jayden realizes that he won't finish in time unless he skims through the rest of the book. If he skims the book, he can cover 15 pages in 10 minutes. If it takes Jayden 5 hours and 50 minutes to finish the book (reading and skimming combined), how many pages did Jayden have to skim through?
WITH STEPSSS
Step-by-step explanation:
Let x be the number of pages that were skimmed through.
Time taken to skim through = 10 * (x/15) = 2/3 x min.
Time taken to read through = 15 * [(275-x)/10] = 1.5(275-x) min.
We have 2/3 x + 1.5(275-x) = 350.
Therefore 412.5 - 5/6 x = 350 and x = 75.
Answer:8pages
Step-by-step explanation:
10minutes/350minutes×275=7.85~8pages

Answer:
y=3x+2
Step-by-step explanation:
For a the equation is y=3x+2 because he makes 3 every hour (3x) and he already has 2 (+2).
For the graph you replace x with any number and solve. Plot the point.
Then you do it again but with a different x.
Finally you draw a straight line trough the 2 points.

Answer:
x=2<br/>y=1
Step-by-step explanation:
\left\{ \begin{array} { l } { 4 x + y = 9 } \\ { 3 x - 2 y = 4 } \end{array} \right.
4x+y=9,3x-2y=4
4x+y=9
4x=-y+9
x=\frac{1}{4}\left(-y+9\right)
x=-\frac{1}{4}y+\frac{9}{4}
3\left(-\frac{1}{4}y+\frac{9}{4}\right)-2y=4
-\frac{3}{4}y+\frac{27}{4}-2y=4
-\frac{11}{4}y+\frac{27}{4}=4
-\frac{11}{4}y=-\frac{11}{4}
y=1
x=\frac{-1+9}{4}
x=2
x=2,y=1

In a certain Algebra 2 class of 27 students, 18 of them play basketball and 16
of them play baseball. There are 3 students who play neither sport. What is
the probability that a student chosen randomly from the class plays
basketball or baseball?
Answer:
The probability is 0.89 or 89%
Step-by-step explanation:
Probability
There are n=27 students in a certain Algebra 2 class. 18 out of them play basketball and 16 of them play baseball.
We also know 3 students play neither sport. This leaves 27-3=24 students playing sports.
The probability that a randomly chosen student plays basketball or baseball is:
[tex]\displastyle p=\frac{24}{27}[/tex]
Simplifying:
[tex]\displastyle p=\frac{8}{9}=0.89[/tex]
The probability is 0.89 or 89%

Solve for x: -2x + 1 = -6
This is a 2-step equation. We will solve it in 2 steps.
[tex]-2x + 1 = -6\\\\-2x = -7\\\\x = \frac{7}{2}[/tex]
The solution for this equation is x = [tex]\frac{7}{2}[/tex].
