Answer:
yes
Step-by-step explanation:
So the circumfrehce of a circle is basically the perimiter of the circle. Let me help with number 1. We need to find the radius. In order to do tuis we divide 6 in half giving us 3. Then we plug in 3 into the circumfrence formula (Pi times the radius multiplied by 2). So it would be 3.14*3*2. The answer for number 1 is 18.85
Given length of a lap = 5/8 mile.
Number of laps Carin ran = 3 1/2 laps.
3 1/2 can be read as 3 and a half. In improper fractions, it can be written as
(3*2+1)/2 = 7/2 laps.
In order to find the total distance covered in 3 1/2 or 7/2 laps, we need to multiply length of a lap by total number of laps ran.
Therefore, total distance covered = 7/2 × 5/8.
=
Multiplying across, we get
= 
=
Let us convert 35/16 into mixed fractions.
On dividing 35 by 16, we get 2 quotient and 3 remainder.
So, the mixed fraction would be 2 3/16.
Therefore, she ran 2 3/16 miles in 3 1/2 laps.
Answer:
we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.
Step-by-step explanation:
Given the expression

SECOND STEP
subtract 3 from the right-hand side as well as on the left-hand side

SOLVING THE REMAINING COMPLETE COMPRESSION

Divide all parts by -2
- Please note that multiply or divide an inequality by a negative number flips the inequality sign.
so the expression becomes


Hence, from the explanation, we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.
