-7 on both sides than divide by -1
X=18
3 1/2 miles = 7/2 miles
1/2 hours= 30 minutes
So,
In 30 mins, travelled 7/2 miles
In 1 min, travelled 7/2 ÷ 30= 7/2× 1/30 = (7×1)/(2×30) = 7/60 miles
In 60 mins, travelled (7×60)/60 miles = 420/60 miles = 7 miles.
Hence, the speed is 7 miles per hour.
well you cant really be expecting us to answer all that, so make sure you specify exactly WHAT you want to be answered.
62. -2(x - 1) + 5x = 2(2x - 1)
...multiply -2
-2x + 2 + 5x = 2(2x - 1)
...multiply 2
-2x + 2 + 5x = 4x - 2
...simplify
3x + 2 = 4x - 2
...add 2
3x + 4 = 4x
...subtract 3x
4 = x
Answer:
Draw a square and pentagon
Step-by-step explanation:
they are both polygons
Your answer would be (4x)(4x² - 2x + 3).
