8a+ 5 - 10a -11 simplify by combining like terms

Answer:

180 people

Step-by-step explanation:

If there are 5 people for each table and there are 36 tables, so then you would need to multiply 36 by 5, because you wouldn't want to add 5 people 36 times lol, so then when you multiply them together, you would get 180 people in total in the restaurant. :-)

Answer:

$1.10

Step-by-step explanation:

We have been that Alex went to the grocery store and bought 5 avocados. He paid $10 and received $4.50 in change.

First of all, we will find amount paid for 5 avocados by subtracting $4.50 from $10.

[tex]\text{Amount paid for 5 avocados}=\$10-\$4.50[/tex]

[tex]\text{Amount paid for 5 avocados}=\$5.50[/tex]

Now, we will divide $5.50 by 5 to find cost of each avocado.

[tex]\text{Cost of each avocado}=\frac{\$5.50}{5}[/tex]

[tex]\text{Cost of each avocado}=\$1.10[/tex]

Therefore, the cost of each avocado is $1.10.

Answer:

Where's the table and graph?

Slope = -6/5

Work is provided in the image attached.

The slope of the line passing through the given points is -6/5.

The slope of a line can be found using the formula: m = (y2 - y1) / (x2 - x1).

In this case, the coordinates of the two points are (-8, -6) and (-18, 6). Applying the formula, we have: m = (6 - (-6)) / (-18 - (-8)) = 12 / (-10) = -6/5.

Therefore, the slope of the line that passes through the points (-8, -6) and (-18, 6) is -6/5.

Answer:

The answer to your question is below

Step-by-step explanation:

Absolute value of  a number, is the value without considering its sign. For example, when we measure distance, we do not say -50 meters, we say "50 meters" because for distance, do not exist negative values.

(A) What is the absolute value of |-10 + -4|

                        | - 10 + -4|  = | - 10 - 4| = | - 14 | = 14

(B) what is the absolute value of |5+2|

                        | 5 + 2 | = |7| = 7

(C) what is the absolute value of |--8.7|

                           | - - 8.7 | = | 8.7 | = 8.7

(D) what is the absolute value of -|-9.2|

                         - | - 9.2 | = - 9.2

D,the quadratic function turning point is (-2,-1) while the other graphs change direction at (-2,3)

Step-by-step explanation:

The point where the graph of a quadratic function changes direction is called a turning point.This is the point where the curve changes to face up or down according to the function.The functions in A,B and C have a common turning point (-2,3) that also appears in the table.The function in D has a turning point at (-2,-1) that is different from the other three functions.

The assumption is based on the principle of random sampling, where a representative sample from a larger population can provide valuable insights into the characteristics of the entire population.

By randomly selecting 1,000 ninth graders, Kendra aimed to ensure that the group accurately represents all ninth-grade students in Florida.

While there might be some variation or margin of error, the average height of the sampled group can provide a reasonable estimate of the average height of all ninth-grade students in Florida.

Answer:

Any number plus 0 is the same as the first number.

Step-by-step explanation:

6 + 0 = 6, 8 + 0 = 8,9+ 0 = 9, 100 + 0 = 100.

Conclusion: Any number plus 0 is the number.

For example: x + 0 = x

x is the number.

Answer: 0

Step-by-step explanation:

100+0=100.

Just basic addition too. 100+0=100. That simple.

No other number can give off 100 like 0 can. 100 plus 0 just gives it the number itself.

Just like how 6+0=6. 6 is just being added to itself.

So, your answer for this is 0. No other number can give off a better answer than the 0 for this problem.

Answer:

3 3/4 mls ink.

Step-by-step explanation:

2/3 of a box  corresponds to 2 1/2 mls of ink

So one box .............................. 2 1/2 / 2/3 = 5/2 / 2/3

= 5/2 * 3/2

= 15 / 4

=  3 3/4 mls ink.

It would take approximately 3.75 milliliters of ink to print off an entire box of paper. This is based on the given that 2.5 milliliters prints off 2/3 of a box and the conversion to a full box.

The question is asking about the amount of ink it will take to print an entire box of paper. We are given that a printer cartridge with 2.5 milliliters of ink will print off 2⁄3 of a box of paper. So, if 2.5 ml prints 2⁄3 of a box, we want to find out how much ink prints 1 full box. This is a simple ratio question.

Set up the ratios like this: 2.5 ml (ink) / (2⁄3 box) = X ml (ink) / (1 box) Simplifying this, you find that X = 2.5 ml / 2⁄3, which, when calculated, equals approximately 3.75 ml. This means it will take approximately 3.75 milliliters of ink to print off an entire box of paper.

Answer:

C

Step-by-step explanation:

EFGH is a kite, so EF ≅ FG and EH ≅ HG.

The area of the kite consists of two area of triangles EFG and EHG.

1. Area of triangle EFG:

[tex]A_{\trangle EFG}=\dfrac{1}{2}\cdot EG\cdot h,[/tex]

where h is the height drawn from point F to the side EG.

1. Area of triangle EHG:

[tex]A_{\trangle EHG}=\dfrac{1}{2}\cdot EG\cdot H,[/tex]

where H is the height drawn from point H to the side EG.

3. Note that

[tex]EG \cong \text{rectangle's length}[/tex]

[tex]h+H\cong \text{rectangle's width}[/tex]

So,

[tex]A_{\text{kite }EFGH}\\ \\=A_{\triangle EFG}+A_{\triangle EHG}\\ \\=\dfrac{1}{2}\cdot EG\cdot (h+H)\\ \\=\dfrac{1}{2}\cdot \text{rectangle's length}\cdot \text{rectangle's width}\\ \\=\dfrac{1}{2}A_{\text{rectangle}}[/tex]

Thus, option C is true (the area of the kite doesn't depend on ratio in which points E and G divide the side)

Answer:

C.) The area of EFGH is always 1/2 of the area of the rectangle.

Step-by-step explanation:

Answer:

a

Step-by-step explanation:

Given

2| x - 3 | + 5 = 17 ( subtract 5 from both sides )

2| x - 3 | = 12 ( divide both sides by 2 )

| x - 3 | = 6

The absolute value function always returns a positive value but the expression inside can be positive or negative, that is

x - 3 = 6 OR -( x - 3) = 6

x - 3 = 6 ( add 3 to both sides )

x = 9

OR

-( x - 3) = 6 ← distribute left side

- x + 3 = 6 ( subtract 3 from both sides )

- x = 3 ( multiply both sides by - 1 )

x = - 3

As a check

Substitute these values into the left side of the equation and if equal to the right side then they are the solutions.

x = 9 → 2|9 - 3| + 5 = 2|6| + 5 = (2 × 6) + 5 = 12 + 5 = 17 ← True

x = - 3 → 2|- 3 - 3| + 5 = 2| - 6 | + 5 = (2 × 6) + 5 = 12 + 5 = 17 ← True

Hence x = 9 or x = - 3 are the solutions → a
