Answer:
10
3.59
6 7/12
Step-by-step explanation:
4 - (-6)
= 4+ 6 ( because when we multiply the negative sign with the negative sign we get a positive sign or a plus sign)
= 10
-2.5 + 6.1 -10.3 - (-7.79) -4 + 6 1/2
= -2.5 + 6.1 -10.3 +7.79 -4 + 6.5 [ (-*-=+) ( converting 6 1/2 into decimal = 6.5)]
= 6.1+7.79+ 6.5 -2.5 -10.3-4 { adding the + numbers and - numbers separately}
= 20.39 - 16.8 { subtracting the totals of + and - numbers}
= 3.59
8 5/6 + (-2 1/4)
= 53/6 - 9/4 { Converting into improper fractions}
= 53( 2) - 9(3)/12 { Taking LCM = 12}
= 106-27/12
= 79/12
= 6 7/12
{ Converting into improper fractions and vice versa}
- we multiply the denominator with the whole number and add it to the numerator to get the improper fraction.( 8 5/6= 53/6)
- we divide the numerator with the denominator the answer gives the whole number and the remainder gives the numerator of the proper fraction. ( 79/12 = 6 7/12)
{ Taking LCM = 12}
Factors of 6 are 3 and <u>2</u>
Factors of 4 are 2 and <u>2</u>
Least Common Multiple is taking the common factors and multiplying it with the rest . 2 is common in both . It will be taken once and then multiplied with the other 2 and 3 so we get
LCM = 2*2*3= 12

Answer:
$46
Step-by-step explanation:
Let the amount of money Darius's parents sent to the book fair be represented as:
We are told that:
Darius's parents sent money to the book fair to be split among the four children in his family. After they gave the money to the cashier, she told each child they had $11.50 to spend.
The Equation is give as:
x = 4 × $11.50
x = $46
Therefore, the total amount of money Darius's parents sent to the book fair is $46
There are 2000 pounds in 1 ton
So, to to get how many pounds are in 12 tons, multiply 12 by 2000
12 x 2000 = 24,000
24,000 lbs
