Answer: The sum of 75.2+(57.376+24.8) is 157.376.

Explanation:

The commutative property of addition states that,

a+b=b+a

The associative property of addition states that,

a+(b+c)=(a+b)+a

The given expression is 75.2+(57.376+24.8).

First use commutative property of addition in the parenthesis.

75.2+(57.376+24.8)=75.2+(24.8+57.376)

Now use associative property of addition.

75.2+(24.8+57.376)=(75.2+24.8)+57.376

Now simplify the expression,

(75.2+24.8)+57.376=100+57.376

(75.2+24.8)+57.376=157.376

Therefore, the sum of 75.2+(57.376+24.8) is 157.376.

Which of these is an example of typing at a rate of 42 words per minute?
algol [13]
C. Typing 210 words in 5 minutes.

Explanation:
42 words per minute is equivalent to 210 words in minutes:

Write the 42 wpm and 210 words in 5 mins as a ratio:
42 : 1 and 210 : 5

Multiply both sides in the ratio 42 : 1 by 5:
42 x 5 = 210
1 x 5 = 5
= 210 : 5

Therefore 210 words in 5 mins is an example of the unit rate 42 wom because it is equivalent.

Hope this helps!
