Answer:
∠ A = 66°
Step-by-step explanation:
Supplementary angles sum to 180° thus
∠ A + ∠ B = 180 , substitute values
2x - 14 + 3x - 6 = 180 , that is
5x - 20 = 180 ( add 20 to both sides )
5x = 200 ( divide both sides by 5 )
x = 40
Thus
∠ A = 2x - 14 = 2(40) - 14 = 80 - 14 = 66°
Solve for x in this inequality: -13 < 3x – 7 < 5
Answer:
−2<x<4

You earn $9.20 per hour at your summer job. Identify an inequality that represents the number p of hours you need to work in order to buy a smart phone that costs $299. Item 6 Question 1 You earn $9.20 per hour at your summer job. Identify an inequality that represents the number p of hours you need to work in order to buy a smart phone that costs $299.
Answer:
32 hours 30 minStep-by-step explanation:
Given that your hourly pay is $9.20
say that you work for p hours, then your pay will be 9.20p
we know that p is the number of hours worked.
therefore, to earn $299 you will need to work
299=9.20p-------1
Solving for p we have to divide both sides by 9.20
299/9.20=p
p=32.5
So you have to work 32 hours 30 min to earn $ 299
The work is doing 32 hours and 30 minutes to earn $ 299.
Given that:
Your hourly pay is equal to $9.20
Assume that you work for p hours, then your pay will be 9.20p
Also know that p is the number of hours worked.
Therefore, to earn $299 you will need to work
299=9.20p (1)
Solving for p we have to divide both sides by 9.20
299/9.20=p
p=32.5
So, to work 32 hours 30 min to earn $ 299.

Solve for n.
n+ 1 = 4(n-8)
0 n = 1
O n = 8
0 n = 11
n = 16
?
Answer:
0 n=11
Step-by-step explanation:
1. Distribute
+1=4(−8)
2. Subtract 1 from both sides of the equation
+1=4−32
+1−1=4−32−1
3. Simplify
=4n−33

Jackson Elementary School ordered 25 pizzas for an awards ceremony. At the end of the day, the principal found 8 1/4 pepperoni pizzas and 7 3/4 sausage pizzas left over. What is a reasonable estimate for the number of pizzas the students ate at the awards ceremony?
Answer: 9 pizzas
Step-by-step explanation:
From the question, we are informed that Jackson Elementary School ordered 25 pizzas for an awards ceremony and at the end of the day, the principal found 8 1/4 pepperoni pizzas and 7 3/4 sausage pizzas left over.
A reasonable estimate for the number of pizzas the students ate at the awards ceremony will be:
= 25 - (8 1/4 + 7 3/4)
= 25 - 16
= 9 pizzas
Are the ratios equivalent? 2/3 and 8/12 Explain.
Answer:
Yes.
Step-by-step explanation:
2/3 and 8/12 are equal because of a multiplying factor. To get from 2 to 8, you'd have to multiply by 4. And to get from 3 to 12 you would have to multiply by 4 as well. So that means they are equal because both the numerator and denominator are multiplied by 4.
If two ratios are equal then the ratios are said to be in proportion and equivalent.
The ratios 2/3 and 8/12 are equivalent.
The simplest form of both ratios is 2/3.
What is a ratio?The ratio is the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
If two ratios are equal then the ratios are said to be in proportion and the ratios are said to be equivalent.
We have,
Two ratios:
2/3 and 8/12
We will make the ratios in their simplest form:
2/3 is in the simplest form.
8/12 = 4x2/4x3 = 2/3 is the simplest form.
We see that both the ratios are equal so the ratios 2/3 and 8/12 are in proportion.
Thus,
The ratios 2/3 and 8/12 are equivalent.
The simplest form of both ratios is 2/3.

Solve the following equation for p. What POSITIVE value of p? 10 - 43 - |7p + 12|
Answer:
Subtract

.
−

7
p
+
12
|
Step-by-step explanation:
The positive value of p from the equation is; p = 3
This is about absolute values.
We are given the equation;10 = 43 - |7p + 12|
Let us simplify by subtracting 43 from both sides to leave the right hand side as an absolute value form.10 - 43 = - |7p + 12|
-33 = - |7p + 12|
divide both sides by -1 to get;
33 = |7p + 12|

evaluate the function for f(-3), f(x)=3x+5
Answer:
-4
Step-by-step explanation:
Since we know that -3 takes the place of x in f(x), we can sub in -3 for all x's in the equation.
Using this information, we now have F(-3)=3(-3)+5
Once you solve the right side of the equation, you get f(-3)=-4
if you were to plot this, the points would be (-3,-4), however I believe you're not trying to, so the answer would be -4.
If the 16 boys in the classroom are 40% of the class how many students are there in the class
Answer:
56
Step-by-step explanation:
40+16=56
Answer:
40
Step-by-step explanation:
Set up the equation.
Let the full number of people in the classroom = x
(40%) x = 16 Change 40% to a fraction
(40/100) x = 16 Reduce 40/100 to a decimal
0.4 x = 16 Divide by 0.4
0.4/0.4 x = 16/0.4
x = 40

Answer:
D. reflection then rotation
Step-by-step explanation:
ABC then A'B'C' then A''B''C''
Following this order, you can see that ABC is reflected across the x-axis to create A'B'C'.
A'B'C' is then rotated anticlockwise to create A''B''C''. How do we know this? The vertexes are pointing in different directions. If it was translated then B' would have been facing downwards instead of facing to the right

Write an equation of the graph in slope-intercept form.
A) y=-100/3x+450
B) y=100/3x-450
C) y=450x+100/3
Given:
Consider the below figure attached with this question.
To find:
The equation of the graph in slope-intercept form.
Solution:
From the graph it is clear that, the line passes through (0,450) and (3,350).
So, the equation of line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-450=\dfrac{350-450}{3-0}(x-0)[/tex]
[tex]y-450=\dfrac{-100}{3}x[/tex]
Add 450 on both sides.
[tex]y=-\dfrac{100}{3}x+450[/tex]
Therefore, the correct option is A.

An adult elephant that is 9 ft tall casts a shadow that is 3 ft long. Find the length of the shadow that a 24 ft tree casts and explain your answer.
Answer:
8 feet
Step-by-step explanation:
First, we need to look at the relationship between the elephant and its shadow. The elephant is 9 ft tall and the shadow is 3 ft long, making the elephant 3 times larger than the shadow. Using this information, we can assume that the tree is 3 times larger than its shadow. To find the answer, divide 24 by 3, giving you a final answer of 8 feet long.
24 / 3 = 8
A local carpenter uses the function LaTeX: f\left(x\right)=180xf ( x ) = 180 x to determine the amount earned after selling LaTeX: xx number of book cases. He has to sell between 5 and 10 bookcases each month in order to meet his sales goal. Find the domain for this situation. Group of answer choices
Given:
A local carpenter uses the function f(x) to determine the amount earned after selling x number of book cases.
[tex]f(x)=180x[/tex]
He has to sell between 5 and 10 bookcases each month in order to meet his sales goal.
To find:
The domain for this situation.
Solution:
We have,
[tex]f(x)=180x[/tex]
where, f(x) is the amount earned be carpenter after selling x number of book cases.
Domain is the set of input values.
Here, input values are number of books he has to sell, which can be a fraction value.
Since, he has to sell between 5 and 10 bookcases each month in order to meet his sales goal, therefore the x values must be integers between 5 and 10.
Therefore, the domain for this situation is set of integers between 5 and 10, i.e., {5,6,7,8,9,10}.
