The mathematical property that allows 40 * (25 * 74) = (40 * 25) * 74 would be the Associative Property of Addition and Multiplication. This property means that no matter how the values of an expression are grouped together (or "associating" with each other), the end result will be the same, as long as the symbols are all either multiplication or addition symbols.
Hope that helped =)
Denali- 6.7x70= 469
The building should be strong enough to withstand an earthquake of that magnitude.
Rat Island- 7.8x30=234
The building should be string enough to withstand an earthquake of that magnitude.
Hope this helps! ;)
Sum means additions so n + 8 = (y)
2(y) = n + 12
It is actually written as a mixture of the two. The standard form would
be 70,000, while the word form would be writing seventy thousand. Both
are equally valid but the mixture found here is avoided in literary
writing. Standard form is just a weird way of saying numeral form or Arabic numerals form or anything similar.
Answer:
B. 2.75 mph
Step-by-step explanation:
If it took him 2 hours to walk 5.5 miles, 5.5 ÷ 2 = 2.75, which is what he walked in a single hour, meaning he was walking 2.75 mph
