Which expression is equilvalent to (5g-2h)-(3h+8-4g).
Answer:
9g -5h - 8
Step-by-step explanation:
We first have to get everything out of the parentheses, so we take the negative that is surrounding the parentheses and apply it to the equation inside of it, giving us this: 5g - 2h - 3h - 8 + 4g
Then, all we need to do is simplify it into this expression: 9g -5h - 8
Answer:
9g-5h-8
Step-by-step explanation:
(5g-2h)-(3h+8-4g)
Opening the brackets
5g-2h-3h-8+4g
9g-5h-8

The degrees of rotation that will carry the regular pentagon onto itself is 72,144,216,288
What is a pentagon in geometry?In geometry, a pentagon is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°.
Given here: A regular pentagon is rotated clockwise about center P.
Now Since you have 5 vertices, your starting vertex can land in 5 different starting places and still come up with the same figure. So if you take 360/5 you get 72 degree rotations to each consecutive vertex.
or more specifically 360/5=72
Again therefore the pentagon will coincide itself after every integral multiple of 72
Thus 72, 144,216,288 are the required angles of rotation.

is triangle abc ~ triangle def ?
Answer:
Unable to be determined.
Step-by-step explanation:
AA postulate : 2 corresponding angles that are congruent.
SSS theorem : 3 sides of a triangle that are equal to another triangle's 3 sides.
SAS postulate: 2 sides and their included angle are congruent to another triangle's 2 sides and their included angle.
This would seem to follow the SAS postulate at first, but the angle we are provided is not the included angle of the sides. In triangle ABC, we are analyzing lines AB and AC. Their included angle is A, but we are given the measure for angle B.
Same with DEF; we analyze DE and DF, who share angle A, but we are given angle E as a measure.
Therefore, we cannot determine if the triangles are similar or not.
eva is working two summer jobs, making $16 per hour tutoring and $8 per hour clearing tables. Last week eva worked 3 times as many hours clearing tables as she worked hours tutoring hours and earned a total of $80. Graphically solve a system of equations in order to determine
Answer
y = 3(2) = 6
Thus, she tutored for 2 hours and cleaned tables for 6 hours.
Explanation
These questions are all about writing down mathematically what they are saying in words. Use variables whenever there is an unknown, and try to write equalities based on what is said.
So, taking it one step at a time:
Eva is working two summer jobs,
Cool.
making $16 per hour and $8 per hour clearing tables.
I'm guessing this is $16/hr for tutoring, and $8/hr for clearing tables?
Last week Eva worked 3 times as many hours clearing tables as she worked tutoring hours
Let C = the number of hours Eva worked at clearing tables
Let T = the number of hours Eva worked at tutoring
Last week Eva worked C = 3 * T
and earned a total of $80.
The amount she earned at each place is:
8*C = money from clearing tables
16*T = money from tutoring
8*C + 16*T = 80
Solve a system of equations in order to determine the number of hours Eva worked tutoring last week, X, and the number of hours Eva worked clearing tables last week, Y,
Welp, I guess they wanted X and Y but it doesn't matter. From the equations above we can say:
8*C + 16*T = 80
C = 3*T
That should be enough to solve for:
C = ?
T = ?
Let x = # of hrs spent tutoring, y = # of hrs spent cleaning tables
We know she worked 3 times as many hours cleaning tables as she did tutoring, which implies:
3x = y
Also, her total earnings add up to $80, which implies:
16x + 8y = 80
This gives us the following system of equations:
3x = y
16x + 8y = 80
Let's make the substitution y = 3x into the 2nd equation:
16x + 8(3x) = 80
16x + 24x = 80
40x = 80
x = 2.
Next, plug in x = 2 into the first equation:
y = 3(2) = 6
Thus, she tutored for 2 hours and cleaned tables for 6 hours.
Barbie spent $166 on clothes. She bought some shirts that cost $14 each and some pants that cost $22 each. She bought a total of 9 items. Select the system of equations to determine how many shirts and pants Barbie purchased. Let x represent the number of shirts and y represent the number of pants.
x + y = 166
14x + 22y = 9
x + y = 166, , 14x + 22y = 9,
x + y = 9
22x + 14y = 166
x + y = 9, , 22x + 14y = 166,
x + y = 9
14x + 22y = 166
x + y = 9, , 14x + 22y = 166,
x + y = 36
166x + 9y=14x + 22y
The correct system of equations will be;
⇒ x + y = 9
And, $14x + $22y = $166
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Barbie spent $166 on clothes.
The cost of each pant = $22
The cost of each shirt = $14
Total number of items = 9
Now,
Let number of shirts = x
And, The number of pants = y
Since, Total number of items = 9
So, we can formulate;
⇒ x + y = 9
And, The cost of each pant = $22
The cost of each shirt = $14
So, We can formulate;
⇒ $14x + $22y = $166
Therefore, The correct system of equations will be;
⇒ x + y = 9
And, $14x + $22y = $166

Answer:
(1/2) {ad - cb} both expressions
Step-by-step explanation:
Notice that the area of the triangle in question can be calculated as the area of the larger right angle triangle OSQ MINUS the area of the smaller right angle triangle OPR, and MINUS the area of the trapezoid RSQP.
Given the coordinates of the given points, the formulas for area of triangles and of trapezoid, we have the following area subtractions:
1/2 (a + c) (b +d) - 1/2 a* b - 1/2 c (b + b + d)=
= (1/2) { ab + ad + cb + cd - ab - 2 cb -cd } =
= (1/2) {ad - cb}
On the other hand the matrix expression is giving you 1/2 of the determinant of the given matrix such determinant is: ad - cb
Then we see that the equality is correct since (1/2) of the determinant is also :
(1/2) {ad - cb}

Sally bought a sweater for $24.99 with a 25% discount. What is the price of the
sweater after the discount?
There are two ways to do this, the one that makes more logical sense and the faster one
You can first calculate how much is 25%. You do this by $24.99 × 25 ÷ 100
Since you know how much is "discounted", just minus the answer you get above with the original price ($24.99 - $6.2475)
The quicker way is to recognise that "original price" is always 100%. In other words, you can just do 100% - 25% and get 75%. Then, $24.99×75÷100 is your answer.

Answer:
[tex]3\sqrt{2}[/tex]/2
Step-by-step explanation:
first we take the square root of the top and bottom:
[tex]\frac{\sqrt{72} }{\sqrt{16} }[/tex]
The denominator is 4. The numerator is harder to solve. To solve, we need to look at the factors of 72.
72= 8 * 9. This means that [tex]\sqrt{72} =\sqrt{8} *\sqrt{9} \\[/tex]
We know that the square root of 9 is 3, so now we have
[tex]\frac{3\sqrt{8} }{4}[/tex]
We're almost done!
Since 8= 2*4, and the square root of 4 is 2,
[tex]\frac{3*2*\sqrt{2}}{4}[/tex]
last, we simplify and get
[tex]\frac{3\sqrt{2}}{2}[/tex]

Pedro made a pot of coffee for some friends. he served 34 ounces to his friends and then measured that there were 20 ounces leftover. How much coffee did Pedro make?
Answer:
Pedro made 54 ounces of coffee in total.
Step-by-step explanation:
Identify what you know:
1) Pedro gave his friend 34 ounces of coffee.
2) There was 20 ounces of coffee left over after!
So, we need to add the amount of coffee that his friend had, to the amount that's left, to get the total amount that he made.
Let's make an equation, where x equals the total amount!
34 + 20 = x
OR
x - 34 - 20 = 0
Hope this helps!
Answer:
54
Step-by-step explanation:
34+20= 54 ounces of coffee
