Answer:
Step-by-step explanation:
Let the first term is a and common difference is d.
<u>The nth term is:</u>
<u>We have:</u>
<u>The difference of these terms is:</u>
- (a + 8d) - (a + 5d) = 16 - 15
- 3d = 1
- d = 1/3
<u>Then the first term is:</u>
- a + 5*1/3 = 15
- a = 15 - 5/3 = 13 1/3
<u>The nth term equation is:</u>
- aₙ = 13 1/3 + 1/3(n - 1) = 1/3n + 13
<u>If the nth term is 22, find n:</u>
- 1/3n + 13 = 22
- 1/3n = 22 - 13
- 1/3n = 9
- n = 9*3
- n = 27
Answer:
because there is no cents, so its a whole number, and it will help if u put the answer choices

Answer:
60
Step-by-step explanation:
50 x 6 = 300
40 x 6 = 240
300 - 240= 60

Answer:
Properties of operations help a lot in solving problems related to integers and rational numbers.
<u>Step-by-step explanation:</u>
There are four properties of operations in math. These properties are applicable in case of addition and multipication but not in case of division and subtraction.
These properties are used to solve problems involving rational numbers as well as integers.These properties are associative,commutative, distributive and identity.
commutative property is A+B=B+A
⇒5+4=4+5
and A*B=B*A
⇒5*4=4*5
associative property ( 32+14)+7= 32+(14+7)
( 8*9)*7= 8*(9*7)
Identity property is 35+0= 35
1*58=58
distributive property is 15*21
⇒ 15*(20+1)
⇒15*20+15*1
15*21
⇒ 15*(22-1)
⇒15*22-15*1
