The associative property of multiplication states that (a × b) × c= a × (b × c).
(4 x 8) x 3 = (8 x 4) x 3 is an example of the associative property of multiplication.
Answer:
x=18, m∠1=140, m∠2=40
Step-by-step explanation:
m∠1 and m∠2 will equal up to 180
7x+14+2x+4=180
Combine like-terms
9x+18=180
Subtract 18 from both sides.
9x=162
Divide both sides by 9
x=18
Then plug in 18 for x in the angle measures
7(18)+14=140
2(18)+4=40
Answer:
2.33*10^4
Step-by-step explanation:
Let's subtract the enrollment in 1900 from the enrollment in 1950.
2.7*10^4 - 3.7*10^3
= 27*10^3 - 3.7*10^3
= (27-3.7)*10^3
= 2.33*10^3
2.33*10^4 students.
