(1) 2x + 3y = 31 y
(2) 2x + 3y = x + 7
(3) 31y = x + 7
(3) x = 31y - 7
(2) 2(31y - 7) + 3y = 31y - 7 + 7 ; 62y - 14 + 3y = 31y ; 34y = 14 ; y = 14/34 ; y = 7/17
(3) x = 31y - 7 ; x = 31*(7/17) - 7 ; x = (217 - 119)/17 = 98/17
x = 98/17 ≈ 5.76
y = 7/17 ≈ 0.41

What is the volume of a rock with a density of 45 g/mL and a mass of 855 grams?
Your answer must have units
Answer:
19 mL
Step-by-step explanation:
You want the volume of a rock with density 45 g/mL and mass of 855 g.
VolumeThe units of density are mass per volume, so we can find the volume by dividing the mass by the density. The units basically tell you how to work the problem.
[tex]\dfrac{855\text{ g}}{45\text{ g/mL}}=\dfrac{855}{45}\,\dfrac{\text{g$\cdot$mL}}{\text{g}}=\boxed{19\text{ mL}}[/tex]
__
Additional comment
Sometimes we like the volumes of things that aren't liquid to be expressed in cubic units. 1 mL = 1 cm³, so the volume could be described as 19 cm³.

During his career, player A was named the NBA's MVP one time
less than player B. Player C was MVP four more than half the times of player B. Together, the three players were named MVP 8 times. How many times was each of the players named MVP?
Answer: Player A=1 time
Player B=2 times
Player C=5 times
Step-by-step explanation:
A=B-1
C=4+B/2
A+B+C=8
B-1+B+4+B/2=8
B+B+B/2 -1+4=8
2B+B/2 +3=8
4B/2 +B/2=5
5B/2=5
5B=10
B=2 times
A=B-1
A=2-1
A=1 time
A+B+C=8
1+2+C=8
3+C=8
C=5 times

Graham decided to play football this year instead of getting a part-time job. Last year he made about $1,100 during football season. He also spends about $9 on eating out after each game. His team plays a 10-game season. What is his opportunity cost of playing football?
10,091 because it's a 10 season football season and he spends 9 dollars every game
Step-by-step explanation:

The opportunity cost of playing football for Graham is $1,190.
What is the Opportunity cost?The opportunity cost of certain activity in microeconomic theory is the value or gain given up by engaging in that activity in comparison to engaging in an alternative activity. Simply put, if you do a bone activity, you forfeit the potential to choose another.
Given that Graham made $1,100 during football season. Also, Graham spends about $9 on eating out after each game and his team plays a total of 10 games in a season.
Therefore, the opportunity cost of playing football for Graham is,
Opportunity cost
= Amount that Graham would have made in a part-time job + Total cost of playing football season
= $1,100 + (Number of games × Amount spend in a single game)
= $1,100 + (10×$9)
= $1,100 + $90
= $1,190
Hence, the opportunity cost of playing football for Graham is $1,190.

What is the greatest common factor for the following expression? 3x^2 -9x *
Answer:
[tex]\mathbf{3x}[/tex] is the greatest common factor for the expression: [tex]3x^2 -9x[/tex]
Step-by-step explanation:
We need to find the greatest common factor for the following expression: [tex]3x^2 -9x[/tex]
Greatest common factor is the number, that is divisible by both numbers. In the given expression 3x is the greatest number that is divisible by all the terms
[tex]3x^2 -9x\\3x(x-3)[/tex]
So, [tex]\mathbf{3x}[/tex] is the greatest common factor for the expression: [tex]3x^2 -9x[/tex]

Answer:
10/27
Step-by-step explanation:
Simplify the following:
(5/6)/(9/4)
Multiply the numerator by the reciprocal of the denominator, (5/6)/(9/4) = 5/6×4/9:
(5×4)/(6×9)
The gcd of 4 and 6 is 2, so (5×4)/(6×9) = (5 (2×2))/((2×3) 9) = 2/2×(5×2)/(3×9) = (5×2)/(3×9):
(5×2)/(3×9)
3×9 = 27:
(5×2)/27
5×2 = 10:
