F-1(x) = (3x + 5) / 3
f-1(3) = (9 + 5) / 3 = 14/3
Answer:
5 weeks
Step-by-step explanation:
John deposits $5 per week and has $10, so his equation is 5x + 10.
Jasmine's equation is 3x + 20.
Make them equal to each other and solve for x:
5x + 10 = 3x + 20
Subtract 10 from each side
5x = 3x + 10
Subtract 3x from each side
2x = 10
Divide each side by 2
x = 5
This is the correct answer for this question: The angle of M is 41. Hope this helps answer your question.
57 + 2x + x = 180
57 + 3x = 180
3x = 180 - 57
3x = 123
x = 4
So, the angle of M is 41
Answer: A: 63
Step-by-step explanation:
How i remember doing this, is that I put the numbers in ascending order (as in lowest to highest) and once I'm done i look for the middle number, so you have 22,44,63,63,71,80,92 it helps me by looking at the numbers on the right and left, or put them in groups, so we have 22,44,63 (that's one group) then we have 71,80,92 (that's another group) so the only number we have left is 63 the middle number, that's your answer :]
