Where you just guessing so that somebody would just give you the answers?
All your answers are incorrect.
btw, none of the choices given in #2 and #3 are correct
no on 4). SUM
correction - your #3 answer is correct
wow really but those are my answer choices... for 2 and 3 and for 4 I was going too pick c but it said times so I thought it ment multiplication.
#2
w+(w-12÷2^2•3)•7
= 10+(10-12÷2^2•3)•7
= 10+(10-12÷8•3)•7 , exponents first
= 10+(10-9/2)•7 , division and multiplication in the order the appear
= 10 + (11/2)•7
= 10 + 77/2
= 97/2 or 48.5
To find the answer to the expressions in question 2 and question 3, we can follow the order of operations (also known as PEMDAS):
Question 2: w+(w-12÷2^2•3)•7
First, we need to simplify the expression within the parentheses:
w-12÷2^2•3
To do this, we start by performing the exponentiation:
2^2 = 4
Next, we perform the division:
12 ÷ 4 = 3
Finally, we multiply by 3:
3 • 3 = 9
Now, we substitute this simplified expression back into the original equation:
w + 9 • 7
Next, we perform the multiplication:
9 • 7 = 63
Finally, we add w and 63 to get the answer. Since w is given as 10, the final calculation is:
10 + 63 = 73
Hence, the answer to question 2 is 73.
Question 3: 14-3•4÷6
To simplify this expression, we follow the order of operations:
First, we perform the multiplication:
3 • 4 = 12
Next, we perform the division:
12 ÷ 6 = 2
Finally, we subtract 2 from 14 to get the answer:
14 - 2 = 12
So, the answer to question 3 is 12.
Question 4: Which algebraic expression represents the sum of four times a number and six?
The expression is represented by:
4(x) + 6
Here, "x" represents the unknown number. Multiplying the number by 4 gives us four times the number, and then adding 6 gives us the sum of four times a number and six.
So, the correct algebraic expression for the given question is 4(x) + 6.
