Answer:
c < - 4
Step-by-step explanation:
- 4c - 1 > 15 ( add 1 to both sides )
- 4c > 16
Divide both sides by - 4 , reversing the symbol as a result of dividing by a negative quantity.
c < - 4
Answer:
The hiker's elevation after 145 minutes will be 1958 meters.
Step-by-step explanation:
The equation of the trend line of the scatter plot showing a hiker's elevation is y = 8.77x + 686 .......... (1), where x is in minutes (say) and y is in meters (say).
Now, we have to predict the hiker's elevation after 145 minutes.
So, from equation (1) we get, y = 8.77 × 145 + 686 = 1957.65 ≈ 1958 meters. (Answer)
Let's see
so you have to add the bottom numbers and the top numbers then add the whole numbers so it's 23 15\28
Answer:
4 1/2 + 1 3/5 = 6 1/10 or 61/10
Answer: 91
Step-by-step explanation: I assume you had a typo and mean what did Ana need on the 5th quiz since you only listed 4 quiz scores.
(74 + 92 + 83 + 100 + x)/5 = 88
(349 + x)/5 = 88
((349 +x)/5) x 5 = 88 x 5
349 + x = 440
x = 440-349
x = 91
