A. 13
B. 5
C.–5
D. –13
Use the number line to determine the unknown addend in - 1

Answers

Answer 1
Answer:

Answer:

- 4 + (-5) = - 9

Step-by-step explanation:

In the number line when we move x units to the right-hand side, then this means +x movement and moving x units to the left-hand side, then this means -x movement.

Now, in our case it is asked how many units must be added to - 4 to get - 9.

Since -9 is to the left of -4 on the number line, therefore, we have to move by 5 units to the left-hand side i.e. -5 movement.

Therefore, - 4 + (-5) = - 9

⇒ - 4 - 5 = - 9 (Answer)

-12x1/6x3+48/3 Pleaseee help me

Answers

First, let's look at the first two nomials. -12 / 6 = -2 and x / x3 = 1 / x2

Since the bigger variable is on the bottom, when simplifying it stays on the bottom.

We get -2/ x2 + 16.

48/3 = 16.

6 divded by 2/3 = what

Answers

you keep the first number the way it is, and multiply by the reciprocal of the second number so:

6/1 * 3/2

6*3=18
1*2=2

So then you have 18/2 which is 9

Answer: 9

Explantion:

Divide: 6 : 2/

3

= 6/

· 3/

2

= 6 · 3/

1 · 2

= 18/

2

= 2 · 9/

2 · 1

= 9

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 2/

is 3/

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step, , cancel by a common factor of 2 gives 9/

A circle has a diameter of 12 inches. what is the area of the shaded section. use 3.14 as pi. no a,b,c,d just an exact answer thanks

Answers

Answer:

Area of shaded section is 113.04

Step-by-step explanation:

Area of circle is calculated by formula A=\pi r^(2).

where 'r' is radius.

here given diameter is 12 inches .

so radius is calculated as  r=(d)/(2)=(12)/(2)=6

and value of \pi is 3.14

so, Area is ;

A=\pi r^(2)

Put value of \pi =3.14 and r=6 inches

A=3.14*6^(2)

A=3.14*36

A=113.04

Hence, area of shaded section is 113.04
A = pi r ^2
A = 3.14(6^2)
A= 3.14 (36)
A = 113.04
