Kimm since the function is g(x) = 3(x-2) and we are given g(x)=6 That means: 6 = 3(x-2) Then we need to know what is x? 6 = 3x - 6 (distribute the 3) 12 = 3x (add 6 to both sides) 4 = x (divide both sides by 3)You can check it this way. Is g(4) = 3(4-2) = 6 ? 3*2 = 6
2(3+5x) in the distributive form, would be 2(3)+2(5x)
Answer:
3. 35 adults and 420 children
4. The three numbers are 13, 52 and 16
Step-by-step explanation:
3. Let the number of adults be x.
Since there are 12 times more children than adults,
number of children= 12x
Total number of people= 12x +x
13x= 455
x= 455 ÷13
x= 35
12x= 35(12)
12x= 420
Therefore, there are 35 adults and 420 children at the play.
4. Let the first number be x.
Since the 2nd number is 4 times the first,
2nd number= 4x
Third number is 3 more than the first:
3rd number= x+3
sum of numbers= x +4x +x+3
6x +3= 81 (simplify)
6x= 81 -3 (bring constant to 1 side)
6x= 78 (simplify)
x= 78 ÷6
x= 13
Second number
= 4x
= 4(13) (subst. x=13)
= 52 (expand)
third number
= x +3
= 13 +3 (subst. x=13)
= 16
