Question

B. Evaluate. |14|+|-7|

C. Write the following phrase using symbols. 4 times the sum of x and w.

D. Add. 14+(-11) + (-9)

E. Multiply (-7/13)x(0)

Answer 1

a.) 6-2=4
b.) 21
c.) 4(x+w) or 4x + 4w
d.) -6
e.) 0
Yeah math can get frustrating and confusing. Hope this helps

Answer 2

Explanation and steps for questions:
A) 4

54/9 - 16/8 This can be reduced or simplified 9 does go into 54 evenly and 8 goes into 16 evenly so lets do that.
54/9 = 6 and 16/8 = 2
Your question is:
6 - 2 = 4

B) 21

|14|+|-7| The straight line means the absoluely value of; Absolute values are always positive numbers!
So your question is 14 + 7 = 21

C) 4 (x + w) or 4x + 4w

4 times the sum of x and w.
4 times means (4 x),
the sum of, is the answer to an adding question, and
you are adding x and y (x + y)
4 x ( x + y)

D) -6

14+(-11) + (-9)
The temperature this morning is 14. By the afternoon it will drop 11 degrees and by nightfall it will drop another 9 degrees (dropping would be your negative whereas temperature rising would be your positive number)
Now think!
Starts at 14 then drops 11 (-11) and drops 9 (-9)
It drops a total of 20 (-20)

14 + (-11) + (-9) = -6 OR
14 + (-20) = -6

E) 0

(-7/13) x (0) Any number you multiply by zero is always 0

2 x 0 = 0,
55 x 0 = 0
So, -7/13 x 0 = 0

Answer 3

A.
54/9-16/8
6-2=4

B.
14+7=21

C.
4(x+w)

D.
14+(-11)+(-9)
14-20=-6

E
0

Answer 4

A. 54/9 - 16/8 = 6 - 2 = 4
B. [14] + [-7] = 21
C. 4(x+w)
D. 14 + (-11) + (9) = 3 + (9) = 12
E. definitely 0

Answer 5

a. make the denominators the same, so you can simply add them. multiply 54/9 by 8/8 and 16/8 by 9/9 then sum the results
b. absolute values make everything positive. add 14 and 7
c. 4(x+w), i'm not sure how to word how to do that one
d. when you add a negative, you subtract, 14 - 11 - 9
e. anything times 0 = 0,
anything times 1 = itself, which is how i altered the numbers in (a.), i just multiplied both numbers by 1 in a way that would get me like denominators.

Answer 6

54/9-16/8=6-2=4
b) |14|+|-7|=14+7=21
c) 4*(x+w)
d)14-11-9=-6
e) anything * 0 = 0

Answer 7

6-2=4?

Answer 8

6-2=4(54/9is6 -16/8=-2
-7
4x(x+w)
14+11=3-9=-6
undefined (0)

Answer 9

bear in mind PEMDAS do it in this order, issues in parenthesis, then exponents, then multiplication or branch, then upload or subtract. continually artwork from left to appropriate. so which you're able to do fifty 4÷9 then seventy two÷8 then upload. fifty 4/9 = 6 seventy two/8 = 9 6 + seventy two ÷ 8 6 + 9 =15 15 is your answer! vote for me!

Answer 10

6-2=4
14+7=21
4*(x+W)
14-20=-6
