Answer: x=4
Step-by-step explanation:
multiply each side by the denominator to cancel out the fraction so the new equation is 16=4x then divide by 4 to eliminate the x and 16 divided by 4 is 4 which is the anwser.
19. The marked price of a certain handbag is $400. After two successive
sales, the selling price of the handbag becomes $225. If the discount
per cent in each sale is x%, find the value of x.
Answer:
x = 25%
Step-by-step explanation:
At the first sale of 25% off, the handbag price dropped from $400 to $300. This is because (400 x 0.25 = 100) and (400 - 100 = 300) Therefore, the selling price of the handbag after one sale was $300.
At the second sale of 25% off, the handbag price dropped from $300 to $225. This is because (300 x 0.25 = 75) and (300 - 75 = 225). Therefore, the selling price of the handbag after two sales is $225.
The value of x remained the same for both sales. x = 25% or 0.25

Lenora is a college student with a student loan of $7,500. Her tuition is $3,200 per year. She owns $470 worth of text books and a has a laptop computer worth $950. She also has a meal plan at school for which she pays $250 per month.
Answer:
Lenora’s assets is the text books
Step-by-step explanation:
From the question, we are informed about Lenora who is a college student with;
a student loan of $7,500
a tuition is $3,200 per year.
She owns $470 worth of text books and a has a laptop computer worth $950 and meal plan at school for which she pays $250 per month
Lenora’s assets in this case is her text books since we are told she owns the $470 worth of text books, and from the question other things from tuition to meal plan are on loan.
NOTE: Asset can be regarded as any property/ resources own by business or individual.

which two circles below are congruent? explain your reasoning
Answer:
The first one to the left and the third one.
Step-by-step explanation:
As long as two circles have the same radius/diameter, they are congruent.
Circle 1 has a radius of 22.5.
Circle 2 has a radius of 22.
Circle 3 has a radius of 45/2 = 22.5. (Diameter/2 = radius)
Therefore, Circle 1 and Circle 3 are congruent.

Find the value of the length a x rounded to 1 DP. The diagram is not drawn accurately
Answer:
x ≈ 3.7 m
Step-by-step explanation:
Use the right triangle on the left to find the height h , using the sine ratio
sin39° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{h}{7}[/tex] ( multiply both sides by 7 )
7 × sin39° = h , then
h = 4.4
Using the tangent ration on the right side right triangle, then
tan50° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{x}[/tex] = [tex]\frac{4.4}{x}[/tex] ( multiply both sides by x )
x × tan50° = 4.4 ( divide both sides by tan50° )
x = [tex]\frac{4.4}{tan50}[/tex] ≈ 3.7 m ( to 1 dec. place )
The triangle has length of value is 3.7meters.
What is triangle?A triangle is "closed, 2- dimensional shape with 3 sides, 3 interior angles and three vertices".
According to the question,
To find height (h), use right angle triangle on the left side.
sin39° = [tex]\frac{opposite}{Hypotenuse}[/tex] = [tex]\frac{h}7}[/tex]
7 sin39° = h
height (h) = 4.4 meters.
To find the value 'x', use right angle triangle on the right side.
tan 50° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{7}{x}[/tex].
x tan 50° = 7
x = [tex]\frac{7}{tan50}[/tex] = 3.7 meters.
Hence, the triangle has length of value is 3.7meters.

G(x) = x2 + 8x +12 over x² – 2x-8
a. For what value(s) of x is the function (x) undefined? Explain your reasoning and identify the domain
of the function G(x) in interval notation
Answer:
The domain of the function in interval notation is -∞ < x < -2, -2 < x < 4, x > 4
Step-by-step explanation:
The given function is presented as follows;
[tex]G(x) = \dfrac{x^2 + 8 \cdot x + 12}{x^2 - 2 \cdot x - 8}[/tex]
The function given in rational format will not be defined when the value of the denominator = 0
Therefore, for the function to be undefined, we have;
x² - 2·x - 8 = 0
(x - 4)·(x + 2) = 0
Which gives;
x = 4, or x = -2
Therefore, the function is undefined for x = 4 and x = -2
The domain of the function in interval notation = -∞ < x < -2, -2 < x < 4, x > 4

Answer:
Option D
Step-by-step explanation:
Going through the choices will help determine which option best simulates the random selection of a voter.
Flip a coin three times, and assign outcomes as follows: HHH, HHT, or HTH = Nava; HTT, THH, or THT = Jensen; TTH = Moretti, TTT = Chang.
Given that it is a random selection of the 4 candidates, it means the probability of choosing either one of them is equivalent. From the option, it can be found that Nava and Jensen have a higher chance of being voted than Moretti and Chang, which would not fit the criteria of being randomly selected.
Roll a number cube, and assign outcomes as follows: 1 or 2 = Nava, 3 or 4 = Jensen, 5 = Moretti, 6 = Chang.
Again, Nava and Jensen have a higher chance of being voted than Moretti and Chang. Therefore, this is not the correct option to simulate random selections of the 4 candidates.
Roll a number cube, and assign outcomes as follows: 1, 2, or 3 = Nava, 4 = Jensen, 5 = Moretti, 6 = Chang.
Nava has a higher chance of being voted, so this option does not fit the stimulation.
Flip a coin twice, and assign outcomes as follows: HH = Nava, HT = Jensen, TH = Moretti, TT = Chang
In this scenario, all 4 candidates have an equal chance of being voted, so this option would best simulate the random selection of a voter from the city.

Johan's gift shop needs to mail 45 checks to the bank. If they can put 5 checks in each envelope, how many envelopes how does the shop need to use?
Answer: 9 envelopes
Step-by-step explanation:
Divide the 45 checks into 9 groups of 5.
------------------------------------------------------------------------
| 5 | 5 | 5 | 5 | 5 | 5 | 5 | 5 | 5 |
------------------------------------------------------------------------
45 checks divided into 9 envelopes equals 5 checks per envelope
45 ÷ 5 = 9
Take away one group of 5 checks from the 45 checks. Then take away another group of 5 checks, and another, and another. When there are no more checks, count how many groups you took away. You can take 9 groups away from 45, so that is your answer.
To tell that the answer is 9 groups of 5 checks, follow these steps.
Look at the equation. 45 ÷ 5 = 9.
The amount of groups is what 45 ÷ 5 equals. What the 45 checks is divided by is the amount in each group.
This means that there are 9 groups of 5 checks.

Write an equation in Standard Form (Ax +By = C) of a line that passes through the point (2, -3) and has a slope of 4
Answer:
The standard form of a linear equation is Ax + By = C. When we want to find the slope of the line represented by this equation, we have two options. We can put the equation in slope-intercept form and identify the slope that way, or we can use the formula m = -A/B.
Step-by-step explanation:
The equation of the line in standard form that passes through the point (2, -3) and has a slope of 4 is 4x - y = 5.
To write the equation of a line in standard form (Ax + By = C) that passes through the point (2, -3) and has a slope of 4, we can use the point-slope form of the equation:
y - y1 = m(x - x1)
where (x1, y1) is the given point (2, -3) and m is the slope (which is 4 in this case). Substitute the values into the equation:
y - (-3) = 4(x - 2)
Now, simplify:
y + 3 = 4x - 8
Next, bring all the terms to the left side of the equation to get the standard form:
4x - y = 8 - 3
Finally, simplify the constant term:
4x - y = 5.
