Step-by-step explanation:
f o g(x)
= f(x - 4)
= (x - 4) + 7
= x + 3.
Question A) 2x + 23 is NOT equivalent to 2x + 6.
Question B) 2(2x + 6)
4x + 12
Question C) 2x + 2x + 6 + 6
4x + 12
66 divided by 3 = 22 which equals 1/3 of the tickets. So 2/3 = 44. The 44 children's tickets minus the total tickets sold = 22. The total number of adult tickets sold were 22.
6:18 students in Debra's class own a cellphone. Because there are 24 people in total. Minus the people who already own cellphones. Leaving 18 without cellphones. The ratio is people who have cellphones to people who do not.
24-6=18. Thus, the ratio would be 6:18
Answer:
X= 67
Y= 121
Z= 80
Step-by-step explanation:
To find Y:
(y-9) and 112 are congruent so
y-9=112
y=121
To find Z: (consecutive)
180=121+z+3
180=124+z (combine like terms)
subtract 124 to cancel and move to other side of equation
z= 80
To find X: (consecutive)
180=112+x+1
180=113+x (combine like terms)
subtract 113 to cancel out and move to their side of equation
x = 67
