Step-by-step explanation:
speed = distance/time
speed = 871÷13
speed = 67 mph
distance = speed x time
distance = 67mph X 9hrs
distance = 603 m
I would say the third one. Plug in the x values:
y = -9/3
-9/3 = -3
y = -3
(-9, -3)
The equation is true.
270 (miles) / 6 (hrs) = 45 miles per hr
in 13 hrs.....45 * 13 = 585 miles <==
2.2 x 5.00= 11
Lowest sig figs is 2
7n-22 ≥ 64
1. Move constant to the right.
7n ≥ 64 + 22
2. Combine like terms.
7n ≥ 86
3. Divide 7n by 7 to get n alone.
n ≥ 86
4. Divide 86 by 7.
n ≥ 86 / 7 OR n ≥ 12.29
