14/7
=2
Evaluate 3x – 4 when x=7. The value of the expression is
Answer:
17
Step-by-step explanation:
Answer:
Let's solve your equation step-by-step.
3x+2=14
Step 1: Subtract 2 from both sides.
3x+2−2=14−2
3x=12
Step 2: Divide both sides by 3.
3x /3 = 12/3
x=4

1. Fill in the blank. When you clear out the fractions in the equation you ______.
2. Trey was solving the equation below in class. The teacher has already told Trey his answer is incorrect but he can’t find his mistake. What mistakes has Trey made that are preventing him from getting a correct answer? What is the correct answer?
9514 1404 393
Answer:
1. multiply both sides by 3
2. (a) chose to multiply by 2/3 instead of 3/2; (b) did the multiplications incorrectly, both for the fraction and the integer; (c) x = 9
Step-by-step explanation:
1. If you want to "clear fractions," you multiply by the denominator of the fraction.
3(2/3)x = 3(6)
2x = 18
__
2. The coefficient of x is 2/3. If you want it to be 1, you need to multiply by the multiplicative inverse of 2/3, which is 3/2. Doing that gives ...
(3/2)(2/3)x = (3/2)6
Then simplifying gives ...
x = 18/2 = 9
__
Trey's mistakes were: a) choosing the wrong multiplier; b) carrying out the multiplication incorrectly. (2/3)(2/3) = 4/9, and 6(2/3) = 4. Had Trey done the multiplications correctly, he would have seen that he needed a different multiplier to get to the answer.

What is f(3) for the function f(x) = 2x +5?
Answer:
f(3) = 11
Step-by-step explanation:
To evaluate f(3), substitute x = 3 into f(x), that is
f(3) = 2(3) + 5 = 6 + 5 = 11

Answer:
option 2 is the best answer
Step-by-step explanation:
I actually couldn't tell you 100% how i got this answer, but i narrowed it down to option 2 and option 3 because those ones have the inequality sign facing the correct way, and then I solved the inequalities to see which one made more sense, and option 3 came out as negative and you can't have a negative cost on something, so option 2 is the best answer.

If 24 = 118, what is the measure of each of the other
angles?
Answer:
Step-by-step explanation:
Lines l and m are the parallel lines and line n is a transversal intersecting parallel lines.
Since, m∠2 = m∠4 = 118° [Given]
m∠2 = m∠6 = 118° [Corresponding angles]
m∠4 = m∠8 = 118° [Corresponding angles]
m∠1 + m∠2 = 180° [Linear pair of angles]
m∠1 = 180° - 118° = 62°
m∠1 = m∠5 = 62° [Corresponding angles]
m∠3 = m∠1 = 62° [Corresponding angles]
m∠7 = m∠5 = 62° [Corresponding angles]
A company has recently been hiring new employees. Today the company has 33% more employees than it did a year ago. If there are currently
53,200 employees, how many employees did the company have a year ago?
9514 1404 393
Answer:
400
Step-by-step explanation:
If x represents the number of employees a year ago, the current number is ...
x + 0.33x = 53,200
x = 53,200/1.33 = 400
The company had 400 employees a year ago.
A store is instructed by corporate headquarters to put a markup of 25% on all items. An item costing 8$ is displayed by the store manager at a selling price of 2$. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Answer:
the correct selling price is $10
And, the error is that the manager put the markup percentage as a selling price instead of adding up the markup to the cost price
Step-by-step explanation:
The computation is shown below:
Given that
Markup = 25%
Cost of an item = $8
Selling price of an item = $2
Based on the above information
The amount of markup would be
= 25% × 8%
= $2
Now amount after markup is
= $2 + $8
= $10
Hence, the correct selling price is $10
And, the error is that the manager put the markup percentage as a selling price instead of adding up the markup to the cost price
Answer:
part A:The correct selling price is $10
Part B:And, the error is that the manager put the markup percentage as a selling price instead of adding up the markup to the cost price

what is the slope of a line parallel to slope 2 and Perpendicular to slope 2?
Answer:
it would be right next to the other line
Step-by-step explanation:
determine the equation of the line that passes through points (-4,5) and has a slope of m = -3
Answer:
y=-3x-7
Step-by-step explanation:
You want to find the equation for a line that passes through the point (-4,5) and has a slope of -3.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was -3. So you can right away fill in the equation for a line somewhat to read:
y=-3x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(-4,5). When x of the line is -4, y of the line must be 5.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the -3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-4,5).
So, why not plug in for x the number -4 and for y the number 5? This will allow us to solve for b for the particular line that passes through the point you gave!.
(-4,5). y=mx+b or 5=-3 × -4+b, or solving for b: b=5-(-3)(-4). b=-7.

find the measures of 1 and 4 if 2 = 119 and = 61
Answer:
1 = 61
4 = 119
Step-by-step explanation:
Alternate angles
Answer:
1 = 61 and 4=119
Step-by-step explanation:
If 2=119 then the other side of the angle which is 1 has to equal the sum of 180-119
if you reflected 2 across the x and y axis or in other words swapped places with the angel diagonal from it, this should answer the same thing as 2 hence why 2 equals 4 equals 119
3 would equal 1 which equals 61 as they both make 180 when paired with the angle directly next to it
The length of a rectangle is 5 less than 3 times its width. The perimeter is
78. Find the LENGTH.*
Answer:
The length is 28 and the width is 11
Step-by-step explanation:
To solve this problem, we can make the width as x.
Since the length is 5 less than 3 times the width, it's going to be 3x - 5
So now we've got the length and width, just need to find the perimeter, which is all the sides added up together. They already gave us the perimeter, so we just have to solve the equation:
2(3x - 5) + 2x = 78
6x - 10 + 2x = 78
8x - 10 = 78
8x = 88
x = 11
x = 11, but remember, x is the width, not the length. Since we already found what x is, we just have to plug it into the equation of:
3x - 5
3 × 11 - 5
33 - 5 = 28
Answer: Length = 28 (don't forget to add the unit if there is one)

Can someone one help me
Answer:
28
Step-by-step explanation:
what you do is add 39 plus 74
that answer will give you 113 so then you subtract 180 from that
then you get 67, then what you do is subtract 39 and you would get 28
x = 28
