Answer:

If Kasey bought one drink, she will be able to buy 6 food items

Step-by-step explanation:

We know Kasey has $8 and if she bought one drink, she will have $7.5

We have to find how many food items she can buy (all of them are $1.25)

$7.5/1.25= 6 food items

If Kasey bought one drink, she will be able to buy 6 food items

Hope this helps!

Answer:

6 items

Step-by-step explanation:

8.00 - 0.50 = 7.50

She has $7.50 to spend on food after buying one drink

7.50 ÷ 1.25 = number of food items she can buy

7.50 ÷ 1.25 = 6

Step-by-step explanation:

Answer:

Okays so for 100 guests we can make the equation $5000 ÷ 100 = $50.00

For 100 guests at the wedding it would cost $50.00 per plate

For 45 guests we can make the equation $2750 ÷ 45 = $61.111111111111, it would be a repeating decimal

For 45 guests at the wedding, it would cost $61.111111111111

I hope that this can help you! ^‿^

Solve for nn by simplifying both sides of the equation, then isolating the variable.

n=4, −2

Answer:

We know that a modulus gives us the absolute value of a number

Hence,  this modulus will give a positive value, regardless of the actual value in the modulus

| -1 + n | = 3

(-1 + n) or (1 - n) = 3 -------------------This tells us that either one of the values will          give us the same answer

-1 + n = 3   or   1 - n = 3

n = 4          or   n = -2

Answer:

It's actually D (2x - 1)(x+1)

Step-by-step explanation:

The required factor of the polynomial 2x³ - 3x² - 3x + 2 is (2x - 1)(x + 1).

Given that,
One factor of the polynomial 2x3 -3x2 – 3x + 2 is (x - 2), which expression represents the other factor, or factors, of the polynomial is to be determined.

factors can be defined by splitting the value into multipliable values.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
x - 2 is one factor of 2x³ - 3x² - 3x + 2 than
( 2x³ - 3x² - 3x + 2 ) / x - 2 = 2x² + x -1 = (2x - 1)(x + 1)

Thus,  the required factor of the polynomial 2x³ - 3x² - 3x + 2 is (2x - 1)(x + 1).

Answer:

The slope is 1/2.

Step-by-step explanation:

To find the slope of a line, use the equation (y2-y1 / x2-x1)

Let's say (4,3) is x2 and y2. That means (0,-2) is x1 and y1.

(3 - 0) / (4 - -2)

(3 - 0) / (4 + 2)

3/6, which simplifys to 1/2

Answer:

use the formula for a line through two points

[tex]y - y_{1} = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} \times (x - x_{1})[/tex]

plug in the given points:

[tex]y - 7 = \frac{15 - 7}{5 - 1} \times (x - 1)[/tex]

[tex]y = \frac{8}{4} \times (x - 1) + 7[/tex]

[tex]y = 2 \times (x - 1) + 7 \\ y = 2x - 2 + 7 \\ y = 2x + 5[/tex]

Answer:

the answer is 0

Step-by-step explanation:

you distribute the 3 which gives

8 - 3k - 6 = 2 - 3k

then you combine like terms and end up with

2 - 3k = 2 - 3k

then you subtract 2 on each side which gives

- 3k = - 3k

and then when you have to keep combining like terms so you add the 3k on both sides which gives u 0

Answer:

b and 57 are adjacent and supplementary angles so

b+59=180

b=180-59=121

Answer:

123

Step-by-step explanation:

since a straight line is 180° you need to do this:

180°-57°

which is equal to 123

therefore the measure of angle of b is 123°

Drafter

Step-by-step explanation:

Architects utilize geometric principles while designing layouts for their ongoing projects, which can include buildings, electrical systems, and plumbing architecture.

Surveyors use geometry to take exact measurements of boundaries for different types of property.

Mechanical engineers, some of the most diversified engineers, use a multitude of geometric concepts to design mechanical devices, or update existing structures

Drafters use the same geometric knowledge and applications as architects and engineers, drafters create design plans with the use of computer-aided design (CAD) software.

1) Expression

2) Equation

3) Equation

4) Expression

Step-by-step explanation:

An equation always contains an equal sign, so in this case, if it doesn't contain an equal sign, it's an expression.

For 2 and 3, you can see that there is an equal sign, but for 1 and 4, there is not.

Therefore, 1 and 4 are expressions and 2 and 3 are equations.

I hope this helped.

5x+2(x+3) is an expression

5x=2(x+3) is an equation

8m-3m+5-16 is an expression

An equation always and I mean ALWAYS uses a = sign.

An expression is a combination of numbers and variables and symbols.
