The system of equations for find b, the number of black-and-white copies, and c, the number of color copies that the customer paid for at the print shop is,
⇒ b + c = 68
⇒ 0.08b + 0.15c = 6
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
Total amount paid = $6.00
Total copies = 68
Cost of black-and-white copy = $0.08
Cost of color copy = $0.15
Now, Let number of black-and-white copies = b
And, Number of color copies = c
Hence, The equation become;
b + c = 68
0.08b + 0.15c = 6
Therefore, The system of equations for find b, the number of black-and-white copies, and c, the number of color copies that the customer paid for at the print shop is,
⇒ b + c = 68
⇒ 0.08b + 0.15c = $6

Answer:
Both calculated the slope as 2/9
Step-by-step explanation:
The area of the rectangle is
(18x - 12) square inches.
Write an expression that represents the
length of the rectangle (in inches).
Answer:
L = 3x - 2
P = 6x - 10
Step-by-step explanation:
Area = length * width
A = l*w
so if the width is 6 inches we can say w = 6
and we can say that l = to the length of the rectangle
if we substitute this:
(18x - 12) = l * 6
we get the answer l = 3x - 2 since we divide both sides by 6.
the expression for length of the rectangle is -> l = 3x - 2
for the perimeter:
P = 2(l + w)
if we substitute this:
P = 2(3x - 2) + 6
distributive property:
P = 2(3x) - 2(2) + 6
then would be:
P = 6x - 4 + 6
(combine like terms) -> P = 6x - (4 + 6)
then you would get: P = 6x - 10
which can also be writtern as -> P = 6x + (-10)
but this is not simplified so you would just write it as 6x - 10

Annisa wrote an expression that represents
“the product of 6.2 and the sum of 3c and 8.”
What are the factors of the expression?
Answer:
“the product of 6.2 and the sum of 3c and 8'' will be algebraically represented as:
⇒ (6.2) (3c + 8)
We know that the numbers that we multiply are the factors of the product.
Here, (6.2) and (3c+8) are the factors of the expression.
Step-by-step explanation:
Let us breakdown and translate the word expression into an algebraic expression.
The sum of 3c and 8 is algebraically represented as:
⇒ 3c + 8
Thus, “the product of 6.2 and the sum of 3c and 8'' will be algebraically represented as:
⇒ (6.2) (3c + 8)
We know that the numbers that we multiply are the factors of the product.
Here, (6.2) and (3c+8) are the factors of the expression.

What is the simplified expression?An expression in mathematics is a sentence that is made up of at least of two numbers or variables and has at least one mathematical operation in it. An expression does not have an equal to sign (=). An example of an expression is 2 + x .
A constant is a value in an expression that never changes in value. For example, in the expression 2x + 5x, 2 is the constant.
Mia's holes = x
Isabelle's holes = 2x - 16
Erick's holes = 10 + x
Sum of holes = x + 2x - 16 + 10 + x
To simplify, add similar terms together : 4x - 6

A 16 oz bottle of a new soda costs $3.59. What is the unit rate, rounded to the nearest tenth of a cent?
The unit rate is __ cents per oz.
The unit rate is 22.5 cents per oz .
The unit rate of any quantity is calculated by dividing (total cost) with (total units purchased).
For Example : If 12 bananas cost $120 then 1 banana will cost 120/12=$10.
In the given question
16oz bottle costs $3.59.
As we have to find the unit rate in cents per oz , we first convert $3.59 to cents.
We know that
$1=100cents
$3.59=100*3.59
=359cents
So the price of 16 oz bottle = 359 cents
Unit rate = (total price ) / (units purchased)
Substituting the total price as 359 cents and units purchased as 16oz.
Unit rate = 359/16
=22.4375
≅22.5
Therefore , the unit rate is 22.5 cents per oz.

Answer:
87, if it were 45 degrees, it would be 90, closest to 90 is 87
Answer:
87 feet
Step-by-step explanation:
We have an angle that's 44 degrees and we know that Susan is 90 feet from the base of the tree. We need to know the height of the tree, which is the value opposite from the angle we know.
Use tangent to find height.
tan (44) = x / 90 then multiply both sides by 90
x = tan (44) * 90 evaluate tan(44) and substitute into the equation
x = 86.911
