Question

can you please help me translate
48 divided by the sum of 3 and 9 into numerical expression

unklerhaukus · Answer

$$48 \div (3+9)$$

anonymous · Answer

$$48\div(3+9)$$

anonymous · Answer

ok thanks i have another if u could help with it also plz

unklerhaukus · Answer

sure

anonymous · Answer

and dt gives 4

unklerhaukus · Answer

$$+ \text{d}t =4$$

anonymous · Answer

translate the quotient of 12 plus 8 and 5 into numerical expression

anonymous · Answer

*that (48/12=4)

unklerhaukus · Answer

$$(12+8) \div 5$$

anonymous · Answer

how did u get that answer im confused

anonymous · Answer

then it also says to write result in both horizontel and vertical format????

unklerhaukus · Answer

well the quotient between two numbers ( a and b ) can be written as 
$$a\div b$$or equivalently$$\frac{a}{b}$$

unklerhaukus · Answer

so the first one can also be written as $$\frac{48} {3+9}$$

unklerhaukus · Answer

and the last one $$\frac{12+8}{5}$$

anonymous · Answer

thanks unkle rhaukus i finally get it

unklerhaukus · Answer

yay

did you also know

$$(a+b )\div c = \frac{a+b}{c} =\frac{a}{c} +\frac{b}{c}$$

1 last question just check one i already did:
the sum of twice four and nine

unklerhaukus · Answer

$$( 2\times 4) +9$$

anonymous · Answer

the last part yopu just did we havent quite got that far yet thanks i didnt do it right but i can see where i messed up

anonymous · Answer

it will be some what like this it's only a hint!
Problem:  	 Ms. Jensen likes to divide her class into groups of 2. Use mathematical symbols to represent all the students in her class.	
Solution:  	Let g represent the number of groups in Ms. Jensen's class.
 	Then 2 · g, or 2g can represent "g groups of 2 students".

In the problem above, the variable g represents the number of groups in Ms. Jensen's class. A variable is a symbol used to represent a number in an expression or an equation. The value of this number can vary (change). Let's look at an example in which we use a variable.

Example 1:    	Write each phrase as a mathematical expression.

 	
Phrase	Expression
the sum of nine and eight	9 + 8
the sum of nine and a number x	9 + x

The expression 9 + 8 represents a single number (17). This expression is a numerical expression, (also called an arithmetic expression). The expression 9 + x represents a value that can change. If x is 2, then the expression 9 + x has a value of 11. If x is 6, then the expression has a value of 15. So 9 + x is an algebraic expression. In the next few examples, we will be working solely with algebraic expressions.

hope it helps!!
