Answer:
X = 22
Step-by-step explanation:
f(x) = 3x + 1
f(7) = 3(7) + 1
= 21 + 1
= 22
Answer:
x = 15
Step-by-step explanation:
x + 2x - 2 + 2x - 2 = 71
Solve for x, you get 15.
Answer:
156
Step-by-step explanation:
Let,
Sandwiches sold by Adam, Matt and Clinton = 2x, 7x and 3x
Total sandwiches = 2x + 7x + 3x
=> 12x
But its given that Matt sold 91 sandwiches
So,
7x = 91
x = 91/7
x = 13
=> Total sandwiches = 12x = 12(13) = 156
You would use 1.73 in order to decrease an amount by 73%
