Answer:
The number which is given as statement is 30
Step-by-step explanation:
Given statement as :
Twice the sum of number and 9 is equal to 3 times the difference of the number and four .
Let the number be x
So, <u>According to question </u>
2 × (x + 9) = 3 × (x - 4)
Or, 2 x + 18 = 3 x - 12
or, 18 + 12 = 3 x - 2 x
Or, 30 = x
I.e x = 30
Hence The number which is given as statement is 30 Answer
Answer:
3x - 14
Step-by-step explanation:
f = 2x + 1
2x + 1 * g
g = x - 7
2x + 1 * x - 7 = 3x - 7
3x - 7 * 2 = 3x - 14

Step-by-step explanation:
Answer:
First blank = 236
Second blank = 60
Third blank = 656
Step-by-step explanation:
For first blank; n = 20
f(n) = 7(20) + 96
= 236
For second blank; f(n) = 516
⇒ 516 = 7n + 96
⇒ n = 60
For third blank; n = 80
f(n) = 7(80) + 96
= 656
