Answer:
The correct answer is x = -92/9 or x = -10.2
Step-by-step explanation:
(The error is that the student didn't multiply 8 inside the parenthesis )
Steps to show work:
3/4x + 8 = 1/3
9x + 96 = 4 ➙ 9x = 4 - 96
9x = -92
x = -10.2 or -92/9
Answer to 32:
You need to find a common denominator and then multiply both sides of the equation by that number. You can do practically anything you want one side of the equation, as long as you do it to the other side as well.

Answers
Given:
Jamie receives 15% commission on magazine subscriptions.
One week her sales totaled $860.
To find:
Her commission.
Solution:
We have,
Total sales of one week = $860
Rate of commission = 15%
Now,
[tex]Commission=\dfrac{15}{100}\times 860[/tex]
[tex]Commission=\dfrac{15}{10}\times 86[/tex]

b) y = 12.9
c) z = 12
d) 2.75 = w or 2[tex]\frac{3}{4}[/tex] = w
e) t = 4
Step-by-step explanation:
a)
2x = 5
divide both sides of the equation by 2
2x/2 = 5/2
x = 5/2
x = 2.5
b)
y + 1.8 = 14.7
subtract 1.8 from both sides of the equation
y + 1.8 - 1.8 = 14.7 - 1.8
y = 14.7 - 1.8
y = 12.9
c)
6 = 1/2z
divide both sides by 1/2 or multiply both sides by 2
6*2 = 1/2z * 2
6*2 = z
12 = z
d)
3.25 = 0.5 + w
subtract 0.5 from both sides of the equation
3.25 - 0.5 = 0.5 + 2 - 0.5
3.25 - 0.5 = w
2.75 = w

2[tex]\frac{3}{4}[/tex] = w

1/4 is 60% of x. Write a proportion that you can use to find x
Answers
Woooooooo
The required value of x is approximately 0.4167 if 1/4 is 60% of x.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
To write a proportion that we can use to find the value of x, we can use the fact that "1/4 is 60% of x" and set up the proportion:
1/4 = (60/100) × x
Here, we have converted 60% to its equivalent decimal form (0.60) and 100% to its equivalent fraction (1).
We can then cross-multiply to solve for x:
1/4 × 1 = 0.60 × x
1/4 = 0.60x
0.25 = 0.60x
x = (0.25) / 0.60
x ≈ 0.4167
Therefore, the value of x is approximately 0.4167.

Traveling from City 1 to City 2, a pilot planned a southeast course along the path labeled d. Instead, a storm forced the pilot to travel 32 miles south, then 24 miles east to reach City 2. How many extra miles was the pilot forced to fly?
A. 13 mi.
B. 14 mi.
C. 16 mi.
D. 17 mi.
Answers
The extra miles the pilot was forced to fly, found using Pythagorean Theorem was 16 miles. The correct option is therefore;
C. 16 mi
What does Pythagorean Theorem state?Pythagorean theorem can be stated as follows; The square of the length of the hypotenuse side of a right triangle is equivalent to the sum of the square of the lengths of the other two sides.
The direction the pilot planned initially = A southeast course
The direction the storm forced the pilot to travel = 32 miles south then 24 miles east
The number of extra miles the pilot is forced to fly = Required
Taking the original path as a straight line, and the destination arrived at being that of the new destination, we get by using Pythagoras Theorem
Direct distance, d₁ = √(32² + 24²) = 40The direct distance from City 1 to City 2 = 40 milesThe new distance can be obtained by the scalar addition of the individual distances as follows;
d₂ = 32 + 24 = 56
The new distance traveled, d₂ is 56 milesThe number of extra miles, Δd, is therefore;
Δd = d₂ - d₁Which indicates that we have;
Δd = 56 miles - 40 miles = 16 milesThe number of extra miles the pilot was forced to fly is Δd = 16 milesLearn more about Pythagorean Theorem in mathematics here:

Which one of the following reasons does NOT explain why 2x + 3y ≠ 5xy?
Answers
Answer:
Since 2 and 3 are factors, they should be multiplied to get 6xy.
Step-by-step explanation:
The solution is Option B.
Since 2 and 3 are factors, they should be multiplied to get 6xy and the equation is False
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
2x + 3y ≠ 5xy
a)
If you substitute 4 for x and 5 for y in the expression 2x+3y, it does not equal 5(4)(5)
Substituting the value of x = 4 and y = 5 in the equation , we get
2 ( 4 ) + 3 ( 5 ) ≠ 5 ( 4 ) ( 5 )
8 + 15 ≠ 100
23 ≠ 100
Therefore , the statement is True
b)
Since 2 and 3 are factors, they should be multiplied to get 6xy
2x ( 3y ) = 6xy
But the equation does not equals 6xy
Hence , the statement is False and does not explain the given equation
c)
x and y are not like terms
The statement is true because the variables x and y are not the same
Therefore , the statement is True
d)
Adding x and y is not the same as multiplying x and y
The value of the equation x + y = x + y and on multiplying x and y = xy
And , x + y ≠ xy
Therefore , the statement is True
Hence , the equation 2x ( 3y ) = 6xy is False
