PLEASE HELP URGENTLY!!
Answer:
x = 69
Step-by-step explanation:
since AB is parallel to CD we can find the value of y with the following equation :
2y - 40 = 66 add 40 to both sides
2y = 110 divide both sides by 2
y = 55
from supplementary angles, we know that the exterior angle's measure is 124
since the sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle
y + x = 124 we found value of y earlier
55 + x = 124 subtract 55 from both sides
x = 69
Solve the formula A = lw for /
Answer:

8x - 12
6x + 8
x = [?]
Answer:
x = 10
Step-by-step explanation:
8x-12 = 6x+ 8
or, 8x -6x = 8 + 12
or, 2x = 20
or, x = 20/2
so, x = 10
Answer:
10
there is a problem with the question...
IF it was : 8x - 12 = 6x + 8
then the answer would be: 2x = 20 .... x = 10

Two cards are drawn from a deck of 52 playing cards. The first card is replaced into the deck before the 2nd card is drawn. What is the probability drawing Ace of Spades and any King?
Answer:
1/676
Step-by-step explanation:
There are 52 cards
P(Ace of spades) = Number of aces of spades / total = 1/ 52
The replace the card
There are 52 cards
There are 4 kings
P(king) = number of kings / total = 4/52 = 1/13
P( ace of spades , replace, any king) = 1/52 * 1/13 = 1 /676

From the given figures, find the length of unknowns sides of Pythagorean theorem. (In solution)
Answer:
61cm
Step-by-step explanation:
A right angled triangle is given to us with two sides as 11cm and 60 cm .We need to find out the length of the third side . Here , since it is a right angle triangle we can apply the Pythagoras theorem .
Pythagoras Theorem :- In a right angle triangle sum of squares of perpendicular and base is equal to the square of hypotenuse.
[tex]\rm\implies hypontenuse^2 = base^2+perpendicular^2[/tex]
As we can see that here ,
Base = 11cm
Perpendicular = 60cm.
[tex]\rm\implies Hypontenuse^2 = Perpendicular^2+Base^2 [/tex]
Substitute the respective values ,
[tex]\rm\implies h^2 = (11cm)^2+(60cm)^2 [/tex]
Simplifying ,
[tex]\rm\implies h^2 = 121cm^2+3600cm^2 [/tex]
Add the numbers on RHS ,
[tex]\rm\implies h^2= 3721 [/tex]
Take squareroot on both sides ,
[tex]\rm\implies h =\sqrt{61\times 61}[/tex]
Simplify the squareroot ,
[tex]\rm\implies \boxed{\blue{\rm Hypontenuse= 61 cm }}[/tex]
Hence the hypontenuse of the triangle is 61cm .

What is the solution to the system of equations graphed below? PLSSS HELP
Answer:
C (-2,0)
Step-by-step explanation:
Find the point where they intersect. It's (-2,0) on the graph
Answer:
C
Step-by-step explanation:
Looking at the graph, the solution is (-2, 0).
This is because on the x axis, the point is 2 units to left (negative number) and does not move on the y axis (leaving it at 0).
Another way to see this is by plugging in these coordinates into the system of equations:
0 = -2(-2) - 4
0 = 4 - 4
0 = 0
0 = -2 + 2
0 = 0
These are both correct, once again proving the solution is (-2, 0).
Question 2 (1 point)
Match each situation to a linear system below.
A child has a piggy bank full
of $1 and $2 coins totalling
$37.
There are 25 more $1 coins
than there are $2 coins.
1. x + 2y = 37
x - y = 25
An exam that is worth 37
marks contains 25
questions.
The questions are either
worth 1 mark or 2 marks.
2. x + 2y = 37
x + y = 25
18
3. x - 2y = 37
x + y = 25
The sum of two numbers is
25.
The first number is 37 more
than 2 times the second
number
Answer:
See answers below
Step-by-step explanation:
For the expression
The sum of two numbers is 25. The first number is 37 more than 2 times the second number
Let the two numbers be x and y
If the sum is 25, then;
x + y = 25 .... 1
37 more than 2 times the second the number is expressed as;
37+2y
If the first number is 37 more than 2 times the second number, then;
x = 37 + 2y
x - 2y = 37 ...2
This shows that the simultaneous equation that fits the expressions are;
x - 2y = 37
x + y = 25
For the expression
A child has a piggy bank full of $1 and $2 coins totaling $37. There are 25 more $1 coins than there are $2 coins.
Let x be the $1 coins
Let y be the $2 coins
If a child has a piggy bank full of $1 and $2 coins totaling $37, then;
x + 2y = 37 ... 1
Also, if there are 25 more $1 coins than there are $2 coins, then;
x = 25 + y
x - y = 25 ...2
The equivalent expressions for the statement will be;
x + 2y = 37
x - y = 25
This hence leaves us with the last;
An exam that is worth 37 marks contain 25 questions. The questions are either worth 1 mark or 2 marks. The resulting simultaneous equation will be;
x + 2y = 37
x + y = 25
I don’t understand what A is trying to ask please could someone help me? Thank you!
You have the right idea. You'll apply a y-axis reflection to go from above the x axis to below it. This allows us to move the red line into the correct vertical position without having to use a vertical translation.
Afterward, you'll shift the red line 4 units to the right to have it line up perfectly with the blue line.
Going from f(x) to -f(x) is the y-axis reflection part
Going from -f(x) to -f(x-4) will shift the line 4 units to the right.

Good evening, I would need some help on this exercise.
Paul takes advantage of the sales to buy pants for € 29.50 which initially cost € 5 more. He also buys a € 17 T-shirt on which he is entitled to a 25% discount at the cash desk. What percentage of the total amount of his purchases did he save by purchasing these items during the sales?
thank you
Answer:
He Saved 18.664%
Step-by-step explanation:
Well first we need to find the total of the original price of the items he got
then we can solve for how much (in percentage) he saved
We know the original price of the pant as € 34.50 because 5+29.50=34.50
Now lets find out the original price of the shirt
The shirt's original price can be found by using this equation
x * .75 = 17
17/ .75 = x
22.67 = x
Now since we know the prices of these two items lets add them together
34.50 + 22.67 = 57.17
He actually spent
29.50 + 17 = 46.5
Now what percentage of 57.17 is 46.5?
We can use 46.5/57.17 = 0.81336
.81336 *100 = 81.336%
100-81.336 = 18.664
18.664% was saved

Answer:
6 dogs
Step-by-step explanation:
To begin, we can start with that we know we want to work with two separate fractions. When we're doing this, we can make the denominators the same to make the comparisons easier.
Our two fractions are 1/8 and 3/4. To find a denominator that can work, we need to find the least common multiple. We can do this by listing the multiples of each number (in this case, the denominators) until one matches.
For 4, we have 4, 8, 12, 16, ...
For 8, we have 8, 16, 24, 32, ...
The lowest number in both of these is 8. Therefore, 8 is our least common multiple. Since 1/8 already has 8 as its denominator, we only need to change the denominator of 3/4.
To change the denominator, one way we can do this is to take (new denominator)/(old denominator) and multiply that value by both the numerator and denominator. We multiply that value by the numerator as well to ensure that the fraction stays the same.
We can then do (8/4) =2, so we multiply both 3 and 4 by 2 to get 6/8 = 3/4
Going back to our problem, we need to find how many dogs Dillon feeds with 6/8th of a can of food. Each dog takes 1/8th of a can of food every day, so we need to figure out how many times 1/8 goes into 6/8.
Because 1/8 is one-eighth of 8/8, or one whole, we can similarly say that 1/8 is one-sixth of 6/8, or six-eights. Therefore, Dillon has 6 dogs
Are these all correct there part 1, 2,3,and 4

In her employee benefits meeting, Yin has been taking notes as her human resources manager presents the 529 savings plan offered by her employer.
Select the text in Yin’s summary of 529 plans that is not accurate.
States offer 529 plans to help save for college expenses. They invest money in mutual funds, and I won’t have to pay federal taxes on the earnings from the investment. A prepaid 529 plan will allow me to pay tuition in advance at current tuition rates. This is huge! Especially, since tuition rates continue to increase every year. 529 plans have restrictions, but there’s no penalty if withdrawals are made for non-education-related expenses. I can shop around for 529 plans, but my company does sponsor a plan if, or when, I decide to choose one.
Answer:
there is no penalty if withdrawals are made for non-educational related expenses.
