Answer:
x = -18
Step-by-step explanation:
x - (-5)= - 23
you would do the opposite of -5 which is positive 5 and you would add 5 to the negative 5 to cancel out that -5 and add 5 to the -23 which gives you -18 so x = -18

Mean 35.714 Med 38 Mode 44
Step-by-step explanation:
new arrange from lowest to largest numbers
22 27 35 38 40 44 44
mean = plus of all number/ number
= (22+27+35+38+40+44+44)/7
= 35.714
Median = the central value
= 38
Mode = the most frequency
= 44 (2 numbers)
Answer:
The third choice.
Step-by-step explanation:
This is a linear function.
The equation is y = (x - 5)(5x + 4) - 5x^2.
y = 5x^2 - 25x + 4x - 20 - 5x^2
y = 5x^2 - 5x^2 - 21x - 20
y = -21x - 20
That means this is a linear function, with a linear term of -21x and constant term of -20.
Hope this helps!
Answer:
The number of child tickets sold by the amusement park is 189.
Step-by-step explanation:
Let A represent the number of adult tickets and C represents the number of child tickets, therefore we have:
3:1 = C:A .................... (1)
Where;
C = ?
A = 63
Substituting for the value into equation (1), we have:
3:1 = C:63
This can be converted to solve for C as follows:
3 / (3 + 1) = C / (C + 63)
3 / 4 = C / (C + 63)
0.75 = C / (C + 63)
0.75(C + 63) = C
0.75C + (0.75 * 63) = C
0.75C + 47.25 = C
47.25 = C - 0.75C
47.25 = 0.25C
C = 47.25 / 0.25
C = 189
Therefore, the number of child tickets sold by the amusement park is 189.
