Answer:

-3 2/3

Step-by-step explanation:

If the number is positive and they are asking for the absolute value it's always going to be negative of the number they are asking you for the absolute value of. Same thing if it was a negative 3 2/3 then the absolute value of -3 2/3 would be positive 3 2/3.

I hope this helped! <3

Answer: 3.66..

Step-by-step explanation: absolute value is the value of the number from the number 0 on the number line so, 3 ⅔ in decimals is 3.66... so the answer is 3.66... because that is how much the number is if you are counting from 0.

Answer:

Step-by-step explanation:

4(−12)=16

4 x -12 = 16

Himari's solution is incorect.

it should be like shown below.

4 - (−12 ) = 16

4 + 12 = 16

16 = 16

so it equates balance.

Answer: C

Step-by-step explanation:

To find b₂, we need to use our algebraic properties to isolate b₂.

[tex]A=\frac{1}{2}h(b_1+b_2)[/tex]               [multiply both sides by 2]

[tex]2A=h(b_1+b_2)[/tex]               [divide both sides by h]

[tex]\frac{2A}{h} =b_1+b_2[/tex]                    [subtract both sides by b₁]

[tex]b_2=\frac{2A}{h}-b_1[/tex]

Now, we know that C is the correct answer.

1. Positional Notation

2. Doubiling

3. An Online Converter

Step-by-step explanation:

Hey there!!!

We generally multiply using base 2 and keep power that starts from 0 and goes on increasing and add all them at last to convert binary to decimal.

For example:

011110

To convert into decimal follow the steps.

1st step: Multiply with base 2 and keep power from right side starting from 0.

[tex]0 \times {2}^{5} + 1 \times {2}^{4} + 1 \times {2}^{3} + 1 \times {2}^{2} + 1 \times {2}^{1} + 0 \times {2}^{0} [/tex]

2nd step: solve powers and multiply with binary numbers.

This implies;

= 0 + 16 + 8 + 4 + 2 +0

= 30.... is your answer.

Hope it helps....

Answer:

Each bag of pretzels costs $1.75

Step-by-step explanation:

Let the cost of 1 box of popcorn be $x

Let the cost of 1 bag of pretzel be $y

_______________________________________

A customer buys 2 boxes of popcorn and 1 bag of pretzels for $6.75.

cost of 2 box of popcorn =2*$x = $2x

sum of cost 2 boxes of popcorn and 1 bag of pretzels in terms of x and y

2x + y = 6.75    equation A

__________________________________

Another customer buys 1 box of popcorn and 2 bags of pretzels for $6.00

cost of 2 box of pretzel =2*$y = $2y

sum of cost of 1 box of popcorn and 2 bags of pretzels in terms of x and y

x + 2y = 6 equation B

x = 6 - 2y

substituting this value of x in equation A

2(6 - 2y) + y = 6.75  

=> 12 - 4y + y = 6.75

=> -3y = 6.75 - 12 = -5.25

=> y = -5.25/-3 = 1.75

Thus,  Each bag of pretzels costs $1.75

Equation:

3 x 5 = 15

15 cookies is the answer.

Sarah and her 4 friends are 5 people in total.

They are each getting 3 cookies.

You are adding three cookies for each friend. That is the same as multiplying 5 times.

Step-by-step explanation:                                                                                          

What is the first step in solving the inequality StartFraction m minus 2 Over 6 EndFraction < –1?

(A is the correct answer) Multiply both sides by 6.

B: Add 2 to both sides.

C: Change the direction of the inequality.

D; Change the inequality to ≤.

Answer: 7

Step-by-step explanation: For the first figure, 7 + 3 = 10, so the perimeter would be 10 + 10 + 7 + 7, which equals Perimeter = 34. For the other figure, 7 - 4 = 3, so 3 + 14 + 14 + 3 = 34, also. Hope this helps!

Answer:

1000 calories because if 18 cracker are 200 calories and you divied 90 by 18 you get 5 and 5 x 200=1000 calories

Answer/Step-by-step explanation:

Given:

m<2 = 98,

m<3 = 23,

m<8 = 70

m<1 + m<2 = 180° (linear pair)

m<1 + 98 = 180 (substitution)

m<1 = 180 - 98 (subtracting 98 from each side of the equation)

m<1 = 82°

m<2 + m<3 + m<7 = 180° (sum of angles in a triangle)

121 + m<7 = 180 (substitution)

m<7 = 180 - 121 (subtracting 121 from each side)

m<7 = 59°

m<4 = m<7 (alternate angles are congruent)

Therefore,

m<4 = 59°

m<5 + m<4 + m<3 = 180° (angles on a straight line)

m<5 + 59 + 23 = 180 (substitution)

m<5 + 82 = 180

m<5 = 180 - 82 (subtracting 82 from each side)

m<5 = 98°

m<6 + m<7 + m<8 = 180° (angles on a straight line)

m<6 + 59 + 70 = 180 (subtitution)

m<6 + 129 = 180

m<6 = 180 - 129 (subtracting 129 from each side)

m<6 = 51°

m<9 + m<8 + m<4 = 180° (sum of triangle)

m<9 + 70 + 59 = 180 (substitution)

m<9 + 129 = 180

m<9 = 180 - 129

m<9 = 51°

m<10 + m<9 = 180° (linear pair)

m<10 + 51 = 180° (substitution)

m<10 = 180 - 51

m<10 = 129°

Answer: {(-6, -6), (-2,-2), (7,-6),(-5,0)}

Step-by-step explanation:

To find the ordered pairs that represent a function, we want to find one that doesn't have multiple outputs for one input.

{(-6, -6), (-2,-2), (7,-6),(-5,0)} is the correct answer because all the x are different, and have only one output.
