AB=AD and BC=DC
Answer:
The value of x in the given figure is 110°
Step-by-step explanation:
Here, In ΔABD,
AB=AD and ∠ ABD = 35°
Now, ANGLES OPPOSITE TO EQUAL SIDES ARE EQUAL.
As, AB=AD
⇒ ∠ ABD = ∠ ADB = 35°
Now, In ΔABD, by ANGLE SUM PROPERTY:
∠ ABD + ∠ ADB + ∠ DAB = 180°
⇒ 35° + 35° + x = 180°
or, x = 180° - 70° = 110°
⇒ x = 110°
Hence, the value of x = 110°
Answer:
110
Step-by-step explanation:
Since AB=AD, AB = 35 so that means AD = 35. 35+35=70. A triangle is 180, so 180-70=110
Which situation is best modeled by the equation
7-x=3?
CLEAR
CHECK
You spend $7 to enter a theme park, and then $3 per ride.
Three friends each get an equal share of the $7 they
earned.
You have some money left after you spend $7 and $3.
The price of a book, $7, was lowered by some amount to
$3.
Answer:
Step-by-step explanation:
The last one
The equation 7 - x = 3 is best modeled by the situation where the original price of a book at $7 is lowered by an amount of $4 to reach the final price of $3.
The given equation 7 - x = 3 can be used to model a situation where the price of a book, originally $7, is reduced by some amount to $3. After solving the equation by subtracting 7 from both sides and then multiplying by -1, we get x = 4. This means the amount reduced from the original price is $4, which is consistent with a price reduction scenario: the book's original price was $7, and it was reduced by $4, bringing the final price to $3.

Cheryl is organizing her movie collection. If each movie case is
7 inch wide, how many movies can fit on a shelf 5 feet wide?
Answer:
The number of movies that can can fit on shelf of 5 feet is 9 .
Step-by-step explanation:
Given as :
The measure of each movies case = 7 inches wide
Let the number of movies for 5 feet wide = n
Now ,
∵ 1 feet = 12 inches
∴ 5 feet = 12 × 5 = 60 inches
I.e 5 feet = 60 inches
Now, Again
For 7 inches wide , the number of movies = 1
So, for 1 inch wide case, the number of movies = [tex]\frac{1}{7}[/tex]
∴ For 60 inches wide case, the number of movies = [tex]\frac{1}{7}[/tex] × 60
I.e For 60 inches wide case, the number of movies = 8.57 ≈ 9
Hence the number of movies that can can fit on shelf of 5 feet is 9 . Answer

8+5y=(8y-6)-7 how to work it out
the solution is y = 7
Step-by-step explanation:
Given equation is
[tex]8+5y=(8y-6)-7[/tex]
The equation has to be solved for y
So,
Opening brackets first
[tex]8+5y=8y-6-7\\8+5y=8y-13[/tex]
Subtracting 8 from both sides
[tex]8+5y-8=8y-13-8\\5y=8y-21[/tex]
subtracting 8y from both sides
[tex]5y-8y = 8y-21-8y\\-3y=-21y[/tex]
Dividing both sides by -3
[tex]\frac{-3y}{-3} = \frac{-21}{-3}\\y = 7[/tex]
so,
the solution is y = 7

Casey has at most $50 to spend on pants. She wants but 3 identical pairs of pants and has a $10 off coupon. Which inequality models all possible prices,p, in dollars, for a pair of pants that casey can afford?
The inequality that models all possible prices,p, in dollars, for a pair of pants that casey can afford is P ≤ 20
Solution:Given that, Casey has at most $50 to spend on pants.
She wants but 3 identical pairs of pants and has a $10 off coupon.
We have to find which inequality models all possible prices,p, in dollars, for a pair of pants that casey can afford
"p" represents the price in dollars for a pair of pants that casey can afford
Now, we know that,
Money spent casey ≤ $ 50
Cost of 3 identical pairs of pants – coupon worth ≤ 50
3 x cost of 1 pair of pant – 10 ≤ 50
3 x cost of 1 pair of pant ≤ 50 + 10
3 x cost of 1 pair of pant ≤ 60
Cost of 1 pair of pant ≤ 60/3
$ P ≤ 20
P ≤ 20
Hence, the inequality is P ≤ 20
Use mental math. A resort has 380 rooms with space for 6 people. Estimate the greatest number of people who could be in these rooms at the same time. Explain your thinking to a friend or family member. (Don’t do the last part. That was just in the instructions T-T)
Answer:
6 people
Step-by-step explanation:
Since the resort has 380 rooms with space for 6 people, only 6 people can be in these rooms at the same time.
Note: It was not said that each room has space for 6 people but the hotel has space for 6 people
Irrespective of the number of rooms available, the space limit is 6, hence not more than 6 people can be accommodated.

What 5 fractions are between -8/10 and -4/5
Final answer:
The student's request for fractions between -8/10 and -4/5 cannot be fulfilled because these two fractions are equivalent. To provide a meaningful answer, it's assumed that the intended question is to find fractions between -8/10 and -9/10, for which examples are given.
Explanation:
The question is asking for five fractions that are between -8/10 and -4/5. First, notice that -8/10 is equivalent to -4/5, so we actually need to find fractions between two identical values. This is not possible as no fractions can exist between two identical numbers. However, assuming that the question intends for incremental fractions between two different numerators with the same denominator, we could consider finding fractions between -8/10 and -9/10, or between -7/10 and -8/10.
For simplicity, let's find five fractions between -8/10 and -9/10:
-17/20
-18/20
-19/20
-39/40
-79/80
These fractions are chosen because they simplify to values that lie between -8/10 and -9/10 when reduced to the same denominator.
2y+3y-6(y+2)=-y+6 solve for y
Answer:
No solution.
Step-by-step explanation:
Add similar elements: 2y + 3y = 5y
5y - 6 (y + 2) = -y + 6
Apply the distributive Law:
6y - 6 x 2 = 6y - 12
5y - 6y - 12 = -y + 6
Add similar elements: 5y - 6y = -y
-y - 12 = -y + 6
Add 12 to both sides:
-y - 12 + 12 = -y + 6 + 12
Simplify:
-y = -y + 18
Add y to both side:
-y + y = -y + 18 + y
Simplify:
0 = 18

process of elimination? how do I get the answer for this kind of question?
Answer:
(4, 0)
Step-by-step explanation:
To use elimination, you need to make the coefficients of one of the variables the same in each equation. For example, we can multiply the first equation by 2 and the second equation by 3:
6x + 4y = 24
6x + 15y = 24
Now we can subtract the equations, eliminating the x terms.
(6x + 15y) − (6x + 4y) = 24 − 24
11y = 0
y = 0
Now plug into either equation to find x.
3x + 2y = 12
3x + 0 = 12
x = 4

During the first half of a college basketball game, 24,196 people entered the athletic center. During the second half, 2,914 people left and 4,819 people entered. How many people were in the athletic center at the end of the game?
There were 26,101 people in the athletic center at the end of game.
Step-by-step explanation:
Number of people entered = 24196
Number of people left during second half = 2914
Remaining people = 24196 - 2914 = 21282
People entered during second half = 4819
Total people at the end of game = Remaining people + People entered during second half
Total people at the end of game = [tex]21282+4819=26101[/tex]
