Solve for x using cross multiplication.
Answers
Answer: x = 2
Step-by-step explanation:
[tex]$$Solve for $x$ :$$\frac{x+4}{3}=\frac{x+6}{4}$$Multiply both sides by 12 :$$\frac{12(x+4)}{3}=\frac{12(x+6)}{4}$$$$\begin{aligned}&\frac{12}{3}=\frac{3 \times 4}{3}=4 \\&4(x+4)=\frac{12(x+6)}{4}\end{aligned}$$$$\begin{aligned}&\frac{12}{4}=\frac{4 \times 3}{4}=3 \\&4(x+4)=3(x+6)\end{aligned}[/tex]
[tex]$$Expand out terms of the left hand side:$$(4 x+16)=3(x+6)$$Expand out terms of the right hand side:$$4 x+16=(3 x+18)$$Subtract $3 x$ from both sides:$$(4 x-3 x)+16=(3 x-3 x)+18$$$$\begin{aligned}&4 x-3 x=x: \\&x+16=(3 x-3 x)+18\end{aligned}$$[/tex]
[tex]\begin{aligned}&3 x-3 x=0: \\&x+16=18\end{aligned}$ \\\\\ Subtract 16 from both sides:$$\begin{aligned}&x+(16-16)=18-16 \\&16-16=0: \\&x=18-16\end{aligned}$$$$18-16=2$$Answer:$$x=2$$[/tex]
4(x+4) = 3(x+6)
4x + 16 = 3x + 18
4x - 3x = 18 - 16
x = 2

A square coffee table has an area of 150 square inches. What is the length of the coffee table? Round your answer to the nearest hundreth.
Answers
explanation: a square has 4 sides of equal length, meaning you divide 150 by 4 because thats how many sides there are.
Length of the coffee table will be 12.25 inch
What is Area of square?
The area of square is length time width.
Given that;
Area of square coffee table = 150 square inches.
Now,
Area of square = (side)²
Substitute the value of area of square,
Side² = 150
Take square root both sides,
Side = √150
Side = 12.247
After rounding it,
Side = 12.25
Thus, Length of the coffee table will be 12.25 inch.

First , convert the mixed number (the fraction we are dividing by in the given maths problem) into an improper fraction .
Multiply the whole part (1) times the denominator (4) and add the numerator . The result is the numerator of our fraction , and the denominator stays the same .
So now our maths problem looks as follows :
[tex]-\displaystyle\frac{1}{2} :\frac{7}{4}[/tex]
Now turn the fraction you are dividing by over :
[tex]-\displaystyle\frac{1}{2} *\frac{4}{7}[/tex]
Now multiply the numerator of the first fraction times the numerator of the second fraction :
4
Perform the same operation with the denominators :
-4/14
So the result is :
[tex]-\displaystyle\frac{4}{14}[/tex]
Since the above fraction is not in it's simplest form , we divide the top and bottom by 2 (a common factor of both 4 and 14) :

A bag contains 9 pennies , 8 nickels, and 5 dimes. How many quarters should be added to the bag so the probability of drawing a dime is 1/6?
Answers
Answer:
A bag contains 9 pennies, 8 nickels and 5 dimes: 22 coins total
5/30 = 1/6
22 + 8 = 30
8 quarters would give the needed 30 coin total
P(dime) = 5/30 = 1/6
Step-by-step explanation:
No quarters should be added to the bag so the probability of drawing a dime is 1/6
Let x be the number of quarters to be added to the bag.
The probability of drawing a dime can be found by dividing the number of dimes in the bag by the total number of coins in the bag after adding x quarters.
The total number of coins in the bag before adding any quarters is:
9 pennies + 8 nickels + 5 dimes = 22 coins
After adding x quarters, the total number of coins in the bag becomes:
9 pennies + 8 nickels + 5 dimes + x quarters = 22 + x coins
The probability of drawing a dime is given as 1/6.
So, we can set up the equation:
5 / (22 + x) = 1/6
30 = 5(22 + x)
30 = 110 + 5x
-80 = 5x
x = -16
Since x represents the number of quarters to be added, it cannot be negative. Therefore, it is not possible to add any quarters to the bag so that the probability of drawing a dime is 1/6.
Hence, the answer is zero quarters.

On rolling a die, the Sample space of the given event E = {1, 2, 3, 4, 5, 6}
Sample space of numbers less than 5 = {1, 2, 3, 4}
Clearly we can see that the number of favorable outcomes = 4
Hence, P(values less than 5) = 4/6 = 2/3.
To find the complement of rolling a number less than 5, we use the formula P' = 1 - P, where P' is the complement of P.
So, let P' be the complement probability of getting numbers less than 5
Now, P'(numbers less than 5) = 1 - P(numbers less than 5)
= 1 - 2/3
= 1/3.
Hence, the probability of the complement of rolling a number less than 5 by using a six-sided die is 1/3.
What is the mean for Doctor A’s data set on corrective lenses? What is the mean for Doctor B’s data set on corrective lenses? Write a sentence comparing the number of people who wear corrective lenses in the two data sets.
Answers
Answer: Doctor A: 751.6 Doctor B: 755.2 Doctor B has an average of 3.6 more patients wearing corrective lenses than Doctor A.
Step-by-step explanation:
To find the mean for corrective lenses, add up all of the numbers and divide by the number of data points.
Doctor A's mean:
Add up the data points: 745+726+769+765+756+742+747+748+770+738 = 7516. Count the number of data points to get 10. Divide 7516 by 10. 7516/10 = 751.6.
Doctor B's mean:
Add up the data points: 763+736+735+759+748+756+765+761+768+761 = 7552. Divide by 10. 7552/10 = 755.2
Difference:
755.2-751.6 = 3.6
Answer:
Doctor A: 751.6 Doctor B: 755.2 Doctor B has an average of 3.6 more patients wearing corrective lenses than Doctor A.
