Mallory goes to the farmers market every weekend. She buys six apples for $0.75 each and a bagful of oranges that are priced at $1.25 per orange. The total charge is $14.50. Write the equation representing this situation where n represents the number of oranges.
Answer:
Number of oranges = 8
Step-by-step explanation:
let
a = number of apples
n = number of oranges
Number of apples = 6
Cost of each apple = 0.75
Number of oranges = n
Cost of each orange = $1.25
Total cost = $14.50
Total cost = Number of apples * Cost of each apple + Number of oranges * Cost of each orange
14.50 = 6 * 0.75 + n * 1.25
14.50 = 4.5 + 1.25n
14.50 - 4.5 = 1.25n
10 = 1.25n
n = 10 / 1.25
n = 8
Number of oranges = n = 8
Therefore, there are 8 oranges in a bagful of orange

Answer:
The lower left one.
Step-by-step explanation:
If you expand and rearrange it, you will find out both of its constant cancel out, and leave you with 3w=3w. So w have infinite number of solutions.
Answer:
[tex]6(\frac{1}{2} w-1)=3(w-2)[/tex]
Step-by-step explanation:
[tex]6(\frac{1}{2} w-1)=3(w-2)[/tex] (Isolate parentheses)
[tex]3w-6=3w-6[/tex] (Add six to both sides to isolate one variable w)
[tex]3w=3w[/tex] (Divide by three to isolate variable w)
[tex]w=w[/tex]
Because we got [tex]w=w[/tex], that means that any number you put in for w will still get you the same answer, or "infinite answers." If you try, say 5, you would still get the same answer if you put in 9. It has infinite answers.

Answer:
11
Step-by-step explanation:
4s-2/7=6
4s-2=6×7
4s-2=42
4s=42+2
4s=44

s=11
Answer:
s = 11
Step-by-step explanation:
[tex]\frac{4s - 2}{7} = 6[/tex]
[tex]\frac{7}{1} * \frac{4s-2}{7} = 6 * 7\\[/tex]

Write an equation of a line in slope-intercept form for the
given conditions.
passes through (4,33) and (1,21)
Answer:
The desired equation is thus y = 4x + 17
Step-by-step explanation:
The slope-intercept form of the equation of a straight line is y = mx + b. There are two values to find: slope m and y-intercept b.
The line passes through (4, 33). Thus, 33 = m(4) + b.
The line also passes through (1, 21). Thus, 21 = m(1) + b, or m = 21 - b.
Thus we have a system of linear equations to solve, and will use the substitution method:
Substitute 21 - b for m in 33 = 4m + b:
33 = 4(21 - b) + b, which, in expanded form, is 33 = 84 - 4b + b, or
33 = 84 - 3b, of
-51 = -3b.
Thus, b = 17. Since m = 21 - b, when b = 17, m = 21 - 17 = 4
The desired equation is thus y = 4x + 17
Of course there are other ways to find this equation. You could, if you wished, find the slope of the line passing through the given points using the definition of slope, and then find the y-intercept.

Answer:
[tex]\frac{-4x+7}{2(x-2)}[/tex]
Step-by-step explanation:
[tex]For x \neq 1 \\\frac{\frac{3}{x-1}-4}{2-\frac{2}{x-1}}=\frac{\frac{3}{x-1}-\frac{4x-4}{x-1}}{\frac{2x-2}{x-1}-\frac{2}{x-1}}=\frac{\frac{-4x+7}{x-1}}{\frac{2x-4}{x-1}}=\frac{-4x+7}{2(x-2)}[/tex]
The equivalent expression is 2(x - 2) / (-4x + 7).
Option A is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To simplify the given expression:
[3/(x - 1) - 4] / [2 - 2/(x - 1)]
We need to find a common denominator for the two fractions in the numerator and denominator of the main fraction.
The common denominator for the numerator is (x - 1) and for the denominator is 2(x - 1).
We can then rewrite the expression as:
[3 - 4(x - 1)/(x - 1)] / [2(x - 1) - 2/(x - 1)]
Simplifying the numerator by distributing the -4:
(3 - 4x + 4) / (x - 1)
(-4x + 7) / (x - 1)
Now, simplifying the denominator by finding a common denominator:
2(x - 1) - 2/(x - 1)
= (2x - 2 - 2)/(x - 1)
= 2(x - 2)/(x - 1)
Substituting back into the original expression, we get:
(-4x + 7)/(x - 1) / [2(x - 2)/(x - 1)]
Multiplying by the reciprocal of the denominator:
(-4x + 7)/(x - 1) x (x - 1)/[2(x - 2)]
(-4x + 7)/[2(x - 2)]
Therefore,
The equivalent expression is 2(x - 2) / (-4x + 7).

Answer:
x = 23
Step-by-step explanation:
2x + 19 + 5x = 180
I say this because it is an angle that is equivalent to the one adjacent to 2x+19, which is on a straight line. That means it is equal to 180.
7x + 19 = 180
180 - 19 = 7x
161/7 = x
x = 23
Step-by-step explanation:
5x+2x+19=180

The incorrect work of a student to solve an equation 2(y + 4) = 4y is shown below:
Step 1: 2(y + 4) = 4y
Step 2: 2y + 6 = 4y
Step 3: 2y = 6
Step 4: y = 3
Which of the following explains how to correct Step 2 and shows the correct value of y?
1. The equation should be y + 4 = 4y after division by 2; y = 5
2. The equation should be y + 4 = 4y after division by 2; y = 2
3. 2 should be distributed as 2y + 8; y = 4
4. 2 should be distributed as 2y + 8; y = 2
Answer:
3; y=4
Step-by-step explanation:
2 should be distributed as 2y + 8; y = 4
2(y +4) = 4y
2y + 8 = 4y
8 = 2y
y = 4

What is the area of a circle that has a diameter of 16in? A: 50.24 square inches B: 803.84 square inches C: 200.96 square inches D: 25.12 square inches
Answer:
A = 200.96 in² (Answer C)
Step-by-step explanation:
The formula for the area of a circle of radius (not diameter) is A = πr².
Here the diameter is 16 in, so the radius is half that, or 8 in.
Then the area of the circle in question is
A = π(8 in)² = 64π in²
If tis is evaluated, we get A = 200.96 in² (Answer C)
