Answer:
Algebra 1 = 12 books
Algebra 2 = 5 books
Geometry = 6 books
Step-by-step explanation:
Given
Represent
Algebra 1 with A
Algebra 2 with B
Geometry with C
For the quantity
[tex]A + B + C = 23[/tex]
To represent the weight, we have that:
[tex]A = 4lb[/tex]
[tex]B = 5lb[/tex]
[tex]C = 3lb[/tex]
[tex]Total = 93lb[/tex]
This gives:
[tex]4A + 3B + 5C = 93[/tex]
The last sentence in the question can be represented with:
[tex]C + B = A - 1[/tex]
So, the expressions to work with are
[tex]A + B + C = 23[/tex] --- (1)
[tex]4A + 3B + 5C = 93[/tex] --- (2)
[tex]C + B = A - 1[/tex] --- (3)
Substitute A - 1 for B + C in (1)
[tex]A + B + C = 23[/tex]
[tex]A + A - 1 = 23[/tex]
[tex]2A - 1 = 23[/tex]
Solve for 2A
[tex]2A = 23 + 1[/tex]
[tex]2A = 24[/tex]
Solve for A
[tex]A = 12[/tex]
Substitute 12 for A in the (2) & (3)
[tex]4A + 3B + 5C = 93[/tex]
[tex]4 * 12 + 3B + 5C = 93[/tex]
[tex]48 + 3B + 5C = 93[/tex]
[tex]3B + 5C = 93 - 48[/tex]
[tex]3B + 5C = 45[/tex] ---- (4)
[tex]C + B = A - 1[/tex]
[tex]C + B = 12 - 1[/tex]
[tex]C + B = 11[/tex]
Make C the subject
[tex]C = 11 - B[/tex] ----- (5)
Substitute 11 - B for C in (4)
[tex]3B + 5C = 45[/tex]
[tex]3B + 5(11 - B) = 45[/tex]
[tex]3B + 55 - 5B = 45[/tex]
Collect Like Terms
[tex]3B - 5B = 45 - 55[/tex]
[tex]-2B = -10[/tex]
Solve for B
[tex]B = -10/-2[/tex]
[tex]B = 5[/tex]
Substitute 5 for B in (5)
[tex]C = 11 - B[/tex]
[tex]C = 11- 5[/tex]
[tex]C = 6[/tex]

What is the domain of the relation?
Oa. {-1,0, 1, 3)
Oc. { -2,-1, 0, 1, 2, 3}
Ob.{-2, 0, 1,3}
Od. {0, 1, 2, 3}
Answer:
(03.01) The domain of a relation is the output (y) values of the relation the input (x) values of the relation a set of points that pair input values with output values x and y values written in the form (x, y)
{-2, -1, 0, 1, 2, 3} representing the domain of the relation.
What is a function?A relation is a function if it has only One y-value for each x-value.
To determine the domain of a relation, we need to identify all possible values for the input or independent variable.
In this case, without any further information, we can look for the set of numbers provided in the answer choices and determine which set includes all possible values for the input.
Looking at the given answer choices:
A. {-1, 0, 1, 3}
B. {-2, 0, 1, 3}
C. {-2, -1, 0, 1, 2, 3}
D. {0, 1, 2, 3}
Since there is no specific information or restrictions mentioned, the most inclusive set that covers all possible values for the input variable is {-2, -1, 0, 1, 2, 3}.
Therefore, {-2, -1, 0, 1, 2, 3}, representing the domain of the relation.

Answer:
$1000
Step-by-step explanation:
So there is 10,000,000 dollars in the company for the annual employee bonus. There are 10,000 employees in this company. This seems like a simple division problem. So you divide 10,000,000 by 10,000 and you get 1,000. So with that being said each employee should receive $1,000 in total.

Answer:
y = 1/2x + 3
Step-by-step explanation:
The slope of a parallel line is the same as the original.
Find the new y-intercept.
y = 1/2x + b
2 = 1/2(-2) + b
2 = -1 + b

after swimming 60 feet below the surface of the water, a whale swims up 30 feet. use a number line to help you create an equation that shows the new location of the whale in relation to the water's surface.
ANSWER:
A. The equation is -60 + 30 = 30. The whale is 30 feet below the waters surface.
B. The equation is -60 + (-30) = -90. The whale is 90 feet below the waters surface.
C. The equation is -60 + 30 = -90. The whale is 90 feet below the waters surface
D. The equation is -60 + (-30) = -30. The whale is 30 feet below the waters surface.
Answer:
First, in standard notation, we must define our zero.
In this case, would make sense to define the zero in the surface of the water.
(below is a number line so you can see the process to think this)
Then if the whale is swimming 60ft bellow the surface of the water, then the first position of the whale is:
-60
Now the whale goes up 30ft, then the new position of the whale is:
-60ft + 30ft = -30ft.
The correct option is A:
The equation is -60 + 30 = -30. The whale is 30 feet below the water's surface.
(you wrote that the equation was equal to +30 instead of -30 in the option A, i supposed that it was a typo)
Answer:
I belive the answer is A.
Step-by-step explanation:

The basketball team sold pizzas for a fundraiser. They sold large pizzas for $15.00 and medium pizzas for $12.00. If the basketball team sold 96 pizza all together and made $1356, how many of each type of pizza did they sell?
Answer:
93 large, 3 medium
the first thing you gotta do is find the least amount of the smaller number that you can take away until it becomes a multiple of the largest number.
1356-12(1)
1344-12(2)
1332-12(3)
1320 12 factored into 1356 3 times before we reached a multiple of 15 so we subtract 3 from the total number of pizza sold and we have 93 large pizzas and 3 medium pizzas

Solve the equation. If the equation is an identity, choose identity. If it has no solution, choose no solution. 8s−(5s+6)=12(20+6s)
Answer & Step-by-step explanation:
8s - (5s + 6)= 12(20+6s)
8s - 5s - 6 = 240 + 72s
3s - 6 = 240 + 72s
-246 = 69s
s= -246/69
s = - 3 13/23
