Answer:
<u>3 stamps were left over</u>
Step-by-step explanation:
<u>Division</u>
When a number m divides evenly by n the remainder is 0. For example, 120 divides exactly by 30 because 120/30=4 and the remainder is 0.
But 120 does not divide exactly by 50 because 120/50 = 2 and leaves a remainder of 20.
Jeff divided his 1,200 stamps equally among 7 stamp albums. If the division of 1,200 by 7 was exact, there won't be any stamp left over. Let's test it.
1,200/7 is 171.4, obviously is not exact, thus There were stamps left over.
How many?
Multiply the lower integer of division 171 by 7 to get: 171*7 =1,197. This means that 1,200-1,197= 3 stamps were left over
Answer:
Please check the explanation below.
Step-by-step explanation:
Some of the properties are defined as:
- <em>Distributive property</em>
a(b+c) = ab+ac
For example,
suppose a=1, b=2, c=3
1(2+3) = 1(2) + 1(3)
5 = 2+3 = 5
- <em>Subtraction property of Equality</em>
if (a=b), then a-c = b-c
For example,
suppose a=1, b=1, c=3
if a = b ⇒ 1 = 1
then a-c = b-c ⇒ 1-3 = 1 - 3 ⇒ -2 = -2
- <em>Addition property of Equality</em>
if (a=b), then a+c = b+c
For example,
suppose a=1, b=1, c=3
if a = b ⇒ 1 = 1
then a+c = b+c ⇒ 1+3 = 1+3 ⇒ 4 = 4
- <em>Multiplicative property of Equality</em>
if (a=b), then a×c = b×c
For example,
suppose a=1, b=1, c=3
if a = b ⇒ 1 = 1
then a×c = b×c ⇒ 1×3 = 1 × 3 ⇒ 3 = 3
- <em>Division property of Equality</em>
if (a=b), then a÷c = b÷c
For example,
suppose a=1, b=1, c=3
if a = b ⇒ 1 = 1
then a÷c = b÷c ⇒ 1÷3 = 1 ÷ 3 ⇒ 1/3 = 1/3
Let's solve the given equation using the above properties.
5(x+10) = 20 Given
5x+50 = 20 1) Distriburive property ∵ a(b+c) = ab+ac
5x = -30 2) Subtraction property of Equality ∵ if (a=b), then a-c = b-c
x = -6 3) Division property of Equality ∵ if (a=b), then a÷c = b÷c
