Answer:
2+(3-2x2)x1
2+(3-4)x1
2+(-1)x1
<h2>-1x1 = 1</h2>
Step-by-step explanation:
multiplica primeiro dentro dos parentes, efetua a operação dos parenteses, olha os sinais, realiza a subtração e depois a multiplicação final.
Answer is choice C. The reason why is because we're simply moving parenthesis around to regroup terms
(10)(5x)(7) = (10*5)(x*7)
We've grouped up the 10 and 5 together; we've also grouped up the x and 7 together.
Side Note: The specific rule being used is the associative property of multiplication. Algebraically that rule is a*(b*c) = (a*b)*c
The bicyclist's speed as a rate is 40/3 miles per hour
<h3>How to determine the bicyclist's speed as a rate?</h3>
The given parameters are:
- Distance = 40 miles
- Time = 3 hours
The rate is calculated as:
Rate = Distance/Time
Substitute known values
Rate = 40 miles/3 hours
Rewrite as:
Rate = 40/3 miles per hour
Hence, the bicyclist's speed as a rate is 40/3 miles per hour
