4x + 2 < 14
4x < 14 - 2
4x < 12
x < 12/4
x < 3
S = { x <3 }
Answer:
plug in the numbers for radius, and know your formulas. a diameter is 2 times a radius so
Pi or 3.14 times D is the same as 2 times pi times radius.
I run 1 mile every 6 minutes.
My friend runs 1 mile every 7 minutes.
Lowest Common Multiple: LCM ( 6, 7 ) = 42 minutes.
Me : 42 : 6 = 7 miles
My friend : 42 : 7 = 6 miles.
A:b=c:d
7.2:x=1:25. If u see two ratios equal each other, the product of a and d is equal to the product of b and c. This means that (7.2 times 25) is equal to x. This equals 180=x. The actual distance of the trail of 180 km. Hope this helps!
