AB is congruent to AD so let's solve the equation:
[tex] \: \: \: \: \: \: \: \: \: \: \: 8x - 2 = 6x + 4 \\ \frac{ - 6x \: \: \: \: \: \: \: \: \: \: \: = - 6x}{2x - 2 = 4} \\ \frac{ \: \: \: \: \: \: \: \: \: \: + 2 = + 2}{ \frac{2x}{2} = \frac{6}{2} } \\ x = 3[/tex]
☆Now we plug in for AD.
[tex]AD \\ 6x + 4 \\ 6(3) + 4 \\ 18 + 4 \\ 22[/tex]

#4. You can do the Pythagorean theorem
[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ {4}^{2} + {3}^{2} = {c}^{2} \\ {16} + 9 = {c}^{2} \\ \sqrt{25} = {c}^{2} \\ 5 = c[/tex]

The admission tickets to an exhibition at $5 for an adult and $2 for a child. A family of 3 adults and 4 children visited the exhibition. What would be the charge if $50 note was used to buy the tickets?
Given :
The admission tickets to an exhibition at $5 for an adult and $2 for a child.
A family of 3 adults and 4 children visited the exhibition.
To Find :
What would be the charge if $50 note was used to buy the tickets.
Solution :
Charge of 3 adult ticket is, A = $( 5 × 3 ) = $15 .
Charge of 4 children ticket is, C = $( 4 × 2 ) = $8 .
Total amount to pay is :
T = $( 15 + 8 )
T = $23
Therefore, they get $( 50 - 23 ) = $27 change.

What is the largest integer n such that (n^2-38) / (n +1) is an integer?
a. 36
b. 38
c. 72
d. 76
e. None of these
Answer:
a. 36
Step-by-step explanation:
for (n^2-38)/(n+1) to be an integer, n+1 must completely divide, n^2-38.
we check with the options
option a n=36 sutisfies the above condition.
(36^2-38)/36+1 = 1258/37= 34 , which is an integer. Therefore, largest integer would be 36
Whitney has 20 coins in her purse. Some are quarters and some are dimes. The total value of the coins is $3.35. How many quarters does Whitney have?
Answer:
I think it's 15 Quarters.
Step-by-step explanation:
The required number of dimes and quarter Whitney has is 11 and 9 respectively.
Given that,
Whitney has 20 coins in her purse. Some are quarters and some are dimes. The total value of the coins is $3.35. The number of quarters Whitney have is to be determined.
Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
Let the number of dimes be x and the number of quarters be y,
According to ot the question,
x + y = 20
x = 20 - y - - - - (1)
and
0.1x + 0.25y = 3.35
From equation 1
0.1[20 - y] + 0.25y = 3.35
y = 9
Now,
x = 20 - 9
x = 11
Thus, the required number of dimes and quarters Whitney has is 11 and 9 respectively.

A hot air balloon can hold 350 lbs of weight. Tristan wants to ride up in
the hot air balloon. The pilot of the balloon weighs 200 lbs. If Tristan weighs 2300
ounces, can he ride in the hot air balloon with the pilot? Why or why not?
Step-by-step explanation:
First, convert 2,300 ounces into pounds.
2,300oz. - 143.75 pounds
You then need to add the pounds from the pilot and Tristan's.
143.75 + 200 = 343.75
If the hot air balloon can hold 350lbs, then both Tristan and the pilot can ride it together. The reason why they can ride it together is because 343.75 pounds is less than what the hot air balloon can originally hold, which is 350lbs.

Find one pair of prime numbers whose product is an even number.
Answer:
I think it's 1 and two for example 2 times 7 is 14
Step-by-step explanation:
Answer:
2 and 3.
Step-by-step explanation:
To get a product of an even number, you have to either multiply two even numbers together or multiply an even number and an odd number together.
There is only one even prime number- 2.
Therefore, you can have any pair of prime numbers that, when multiplied together, get an even number as long as one of those numbers is 2.
2 and 3 work, as well as 2 and 5. The list goes on and on. Just choose a random prime number (that's not 2) and pair it with 2. It is guaranteed that when you multiply those two numbers together, you will get an even number.
Isabelle is plotting a pentagon on a grid. So far, she has plotted and connected the three points shown on the grid below.
On a coordinate plane, lines connect points (negative 2, 4), (negative 3, 2), and (0, negative 2).

This table shows a proportional relationship. х y Complete the equation that represents the table. - 4 - 6 Enter your answer as a decimal in the box. -2 3 0 0 y = Х 8. 12
Answer:
y = 1.5x
Step-by-step explanation:
An equation that represents a proportional relationship can be written as y = kx.
Where,
k = constant of proportionality or unit rate = y/x
Using a pair form the table of values, say (-2, -3),
k = y/x = -3/-2 = ³/2 = 1.5
Substitute k = 1.5 into y = mx
The equation that represents the table would be:
y = 1.5x
The proportionality constant is 2/3 and the required equation is y = 2/3x
Tables and valuesThe standard equation of a line is expressed as y = mx + b
where:
m is the slope of the line
b is the intercept
From the given question, we are to find the rate of change (slope) from the give table.
USing the coordinate points from the table (-2, 0) and (-3, 0)
Also recall that;
y = kx
-2 = k(-3)
k = 2/3
Hence the proportionality constant is 2/3 and the required equation is y = 2/3x
