Answer:
x = 2
Step-by-step explanation:
x/6 + 1 = 2x - 8/3 (first you want to multiply by 6 on both sides to get rid of x/6)
x + 6 = 12x - 16 (add 16 on both sides)
x + 22 = 12x (subtract x on both sides)
22 = 11x (divide by 11 on both sides)
2 = x

the total amount of tickets sold was $400, how many of each type were sold?
Answers
Answer: 175 adult and 50 children
Step-by-step explanation:
1x+2y=400
x+y=225
subtract x
y=225-x
substitute for y in first set
1x+2(225-x)=400
1x+450-2x=400

Step-by-step explanation:
It is saying that both equations equal each other, as they both equal f(x). So we just move each of the factors to equal each other. Like 3x+5=11. There you just subtract the 5 from both sides to get 3x=6, and then divide both sides by 3 to get x=2.
Answer:
x=2

f(x)=3x+5
11=3x+5

A box contains 90 discs numbered from 2 to 90. If one disc is drawn at a random, find the probability that it bears a two digit number
Answers
Step-by-step explanation:
Let E be the event of drawing a disc from the box of discs numbered from 1 to 90
Two digit numbers from 1 to 90=10,11,12,.....,90
No. of favorable outcomes=81
Total no. of possible outcomes =90
We know that, Probability P(E) =(Total no.of possible outcomes)(No.of favorable outcomes)=9081=109
Therefore, the probability of a two digit numbered disc from the box of discs numbered from 1 to 90=109

Max has a drawer full of green and red socks. He has three times times as many red socks subtracted from four times as many green socks which he believes is 50 socks. Half the number of green socks plus one-third of the number of red socks is 36. How many of each colour does he have?
Answers
Answer:
There are 42 red colour socks and 44 green color socks
Step-by-step explanation:
Let there are r red socks and g green socks.
ATQ,
He has three times times as many red socks subtracted from four times as many green socks which he believes is 50 socks.
4g-3r=50 ....(1)
Half the number of green socks plus one-third of the number of red socks is 36.
[tex]\dfrac{g}{2}+\dfrac{r}{3}=36\\\\3g+2r=216\ .....(2)[/tex]
Multiply equation (1) by 2 and equation (2) by 3.
8g-6r = 100 ....(3)
9g +6r = 648 ....(4)
Add equation (3) and (4)
8g-6r + 9g +6r = 100+648
17g = 748
g = 44
Put the value of g in equation (1).
4(44)-3r=50
176-3r = 50
176-50 = 3r
r = 42
Hence, there are 42 red colour socks and 44 green color socks.

a positive integer n not exceeding 100 is chosen in such a way that if n ≤ 50 , then the probability of choosing n is p , and if n > 50 , then the probability of choosing n is 3 p . the probability that a perfect square is chosen is (a) 0.05 (b) 0.065 (c) 0.08 (d) 0.09 (e) 0.1
Answers
The probability that a perfect square is chosen is 0.08;
P represents the likelihood of selecting the number 'n' such that n>50. There are exactly 7 perfect squares less than 50. Therefore, there is a 7/50 chance of having a perfect square that is less than or equal to 50.
The likelihood of selecting the number "n" such that n>50 is also given as 3p. From 50 to 100, there are precisely 3 perfect squares. Therefore, there is a 3/50 chance of having a perfect square that is higher than 50 and less than or equal to 100.
The chance of selecting any number between "1" and "100" is p+3p=4p.
The probability that the chosen number is a perfect square and less than or equal to 50 is p × 7/50;
The odds that the selected number is larger than 50 but not higher than 100 and a perfect square are 3p × 3/50;
Consequently, the likelihood that any selected number is a perfect square is (p×7/50+3p×3/50)÷4p
If we simplify, we have 0.08.

Answers
Answer:
14-8
12-9
0-15
2-14
Step-by-step explanation:
Combinations for different rows will be, 14 - 8, 12 - 9, 0 - 15, 2 - 14.
Given in the question,
Total number of people = 60Number of players who can play chess = 2Number of players who can play Uno = 4Let the number of chess games played = x
And number of Uno games played = y
Therefore, equation for this situation will be,
2x + 4y = 60
For the 1st row given in the table,
If y = 8,
2x + 4(8) = 60
2x = 28
x = 14
For the 2nd row of the table,
If x = 12,
2(12) + 4y = 60
4y = 36
y = 9
For 3rd row of the table,
If y = 15,
2x + 4(15) = 60
x = 0
For 4th row of the table,
If x = 2,
2(2) + 4y = 60
4y = 56
y = 14
Therefore, combinations for different rows will be, 14 - 8, 12 - 9, 0 - 15, 2 - 14.

In APQR, mZP = (4x – 14)", mZQ = (5x + 6)°, and
mZR = (x - 2)°. Find mZR.
Answers
Answer:
x = 19
m<R = 17°
Step-by-step explanation:
PQR is a triangle and the sum of interior angles in a triangle is equal to 180°
m<P + m<Q + m<R = 180°
4x - 14 + 5x + 6 + x - 2 = 180° add like terms
10x - 10 = 180 add 10 from both sides
10x = 190 divide both sides by 10
x = 19
angle R is x - 2 so if we replace x with the value we found
m<R = 19 - 2 = 17°
