Step-by-step explanation:
Solve the problem step by step.
First,
Base area: 6 * 2.5 = 15
Then,
The area of the two smallersides:
2.5 * 4 = 10
10 * 2 = 20
After that,
The area of the two larger sides:
6 * 4 = 24
24 * 2 = 48
After all of the calculations, you add all of the sums up:
15+20+48
Which equals 83.
The equation form for this problem would be:
(6*2.5) + 2(2.5*4) + 2(6*4) = 83
Hope this helps and it wasn't too confusing!
Adult tickets cost 12$, but kids tickets cost just 8$. If a group of 13 people pay for tickets for this adventure park, and they pay $124, how many kids must be in that group
Step-by-step explanation:
There are x kids in the group
So, adults are 13-x people
(13-x)(12) + x(8) = 124
156 - 12x + 8x = 124
156 - 124 = 4x
4x = 32
x = 8
There are 8 kids in that group.

Answer: Will need 7 week of time to afford a car worth 1932
Step-by-step explanation:
Missing information : car is worth 1932
Will works 7 hours day, 6 days a week.
=> Number of hours worked in a week = 7 * 6 = 42 hrs
paid 9.20 an hour
=> will Weekly payment = 42 *9.2 = 386.4
will : mum = 5:2.
=> Will share = (5/7) * 386.4 = 276
car is worth 1932
Number of Weeks taken by will to afford a car = 1932/276 = 7

Members of a parenting organization want to use a two-sample t test to determine whether the average tuition for private schools in their state is significantly different for high school students than for elementary students. They plan to take tuition estimates from random samples of 10 schools serving each level.
Which of the following are conditions for this type of test?
A. Only sample from schools that include both elementary and high school.
B. The tuition estimates in each group are approximately symmetric with no outliers.
C. There are approximately equal numbers of private elementary schools and high schools in the state.
The conditions for this type of test is that The tuition estimates in each group are approximately symmetric with no outliers.
What are outliers?These are the values in a statistical research that lies in positions that are way off from the values used in the data set.
There would be no outliers used here because all of the tuition estimates would be closely related for the schools.

6x+9(-5x-3) combining like terms

Hope that helps!
I think the question should be as follow:
➙ 6x + 9 - ( 5x - 3 )
➙ 6x + 9 - 5 x + 3
➙ 6x - 5x + 9 + 3
➙ x + 12
➙ x = -12
Anyways I've also solved according to the provided question:
ㅤㅤㅤ➙ 6x + 9 (-5x - 3 )
ㅤㅤㅤ➙ 6x - 45x - 27
ㅤㅤㅤ➙ - 39 x - 27
Further, we can solve for x ;
ㅤㅤㅤ➙ - 39 x - 27 = 0
ㅤㅤㅤ➙ - 39 x = 0 + 27
ㅤㅤㅤ➙ x = - 27 / 39

find the value of x.
Answer:
x = 5
Step-by-step explanation:
Two secants have equal ratios when (in this case) they are split up as
AB * AC = AD*AE
Givens
AB = x-2
AC = (x - 2 + x+ 4) = 2x + 2
AD = 4
AE = 5 + 4 = 9
Substitute and solution
(x - 2) (2x + 2) = 4 (9) Expand the left, Combine the right
2(x^2 - x - 2) = 36 Divide both sides by 2
x^2 - x - 2 = 18 Subtract 18 from both sides
x^2 - x - 2 - 18 = 18 - 18 Combine
x^2 - x - 20 = 0 This factors
(x - 5)(x + 4) = 0 Only one of these factors works
x - 5 = 0 Add 5 to both sides.
x = 5

Edgar is a real estate agent. He earns a 5% commission for every house he sells. Last month Edgar sold three homes. He sold one for $110,000, another for $65,000 and a third house for $78,000. How much did Edgar receive in commission by selling these three homes?
Summing up all the amount in commission made from the three sales we have
= 5500+3250+3900
=$12,650
Percentage of AmountGiven Data
Commission Rate = 5%Amount made from $110,000= 5/100*$110,000
= 0.05*$110,000
= $5500
Amount made from $65,000= 5/100*$65,000
= 0.05*$65,000
= $3250
Amount made from $78,000= 5/100*$78,000
= 0.05*$78,000
= $3900

A rectangle has an area of (4x2 + 10) square inches. The length of the rectangle is (2x2 + 5) inches.
How many inches is the width of the rectangle?
Answer:
Area of the rectangle = 4x^2+8x = 4x(x+2)
So if the length is (x+2), the width of the rectangle = 4x(x+2)/ (x+2) = 4x.
The length is > the width, so
x+2 > 4x, or
2 > 3x, or
(2/3) > x or
x < (2/3).
Say x = 5/9 which is < 2/3, the length = 2 + 5/9 or 23/9 and the width =20/9, which is logical.
