Therefore, the correct answers are: [options 2, 3, and 4]
Answer:
71, 72, 73, 74 . for details, check below
Step-by-step explanation:
a) Let's assume that among the four consecutive numbers, the first one is x,
so, the four consecutive numbers should be:
- x
- x+1
- x+2
- x+3.
According to the question,
(x) + (x + 1) + (x + 2) + (x + 3) = 290
<h2>
b)</h2>
(x) + (x + 1) + (x + 2) + (x + 3) = 290
4x + 6 = 290
4x = 284
x = 284÷ 4
x = 71.
So, the numbers are,
71, 72, 73, 74
1,680 divided by 400 = 4.2
So we know that Xian has done 4.2 laps.
4.2 divided by 14 = 0.3
0.3 x 100 = 30%
Therefore, Xian has finished 30% of the run
3d+ 3s = $21 because they bought three drinks and three snacks
80 miles per hour is 128.74752 kilometers per hour
