Answer:

X = 7

Step-by-step explanation:

because of you do 5+2 = 7 then you minus 3 which you get 4.

the. if you have a production of around 10 you will get 7.

or you can do.

3+2 which is 5 and then you multiply that by 2 which is 10 and then you comprised that number therefore you will get 6 but you have to find X so we youndelie (think that's how u spell it) X which will equal to 1 and 6+1 is 7. once you get it it's quite simple

3 : (1/2) =[tex]\frac{6}{1} =6[/tex]

Step-by-step explanation:

Divide: 3 : [tex]\frac{1}{2} =\frac{3}{1} *\frac{2}{1} =\frac{3 * 2}{1*1} =\frac{6}{1} =6[/tex]

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 [tex]\frac{1}{2}[/tex] is [tex]\frac{2}{1}[/tex]) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.

In words - three divided by one half = six.

1st Q: C. Algebraic Expression; it consists of numbers and a variable.

2nd Q: D. The number of times Chris washes the car.

Step-by-step explanation:

1st Question:

Numerical Expression: Contains numbers and operations. Numerical expressions are your typical 2 + 2 equations. The ones you start learning in Kindergarten with just numbers and different operations such as addition, subtraction, division, and multiplication.

EX: 108 - 24 = ?

? = 84

Algebraic Expression: Contains numbers, operations, and variables. They are the same as normal, numerical expressions with the exception that it also has letters, or variables.

EX: 2x + 3 = 7

x = 2

__________________________________

2nd Question:

Amount Chris earns per wash: $10.00

# of times Chris washes the car: x

So 10x means what...?

10 = earns per wash

x = times washed the car

Multiply 10 by x to find the total Chris earns for the number of times he washes the car, x.

(Just as a reference, this would be counted as an Algebraic Expression).

Hope this helps! :)

(Lmk if you don't understand the explanation for the 2nd Q)

Answer:

Step-by-step explanation

The first step, u have add 10.1 + 2.7 = 12.8 .

Then, u add 12.8 - 12.6 = 00.2.

After that u add 10.1 + 2.7 + 12.6 + 22.9 = 48.3.

If u want u can also add 10.1 + 2.7 + 12.6 to show the total without the North Kailbab Trail added.

Answer:

200<=15x

divide by 15

You have to work at least 13 1/3 hours to earn $200

<= means greater than or equal to

Step-by-step explanation:

The minimum number of hours to earn at least $200 is 14

Let the number of hours be x.

Given that hourly rate is $15, and he needs to earn at least $200;

The inequality of the scenario is:

15x >= 200

Divide both sides by 200

x >= 13.33

The smallest integer greater than 13.33 is 14.

So, we have:

x = 14

Hence, the minimum number of hours is 14

Answer:

Perpendicular

Step-by-step explanation:

Both lines intersect and form a right angle when they intersected each other. Non co-planar means essentially means "on different planes", but both lines do lie on the same plane. Parallel lines don't intersect at all! However lines a and d are intersecting. Skewed means neither parallel nor perpendicular (meaning they intersect and don't form a right angle).

Answer:

It would be perpendicular.

Step-by-step explanation:

Perpendicular lines form a 90-degree angle.

Skew lines are on different planes and do not intersect.

Since A and D intersect with a 90-degree angle they're perpendicular.

The inequality expression of the statement is |2s - 7| >= -1

Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal

The mathematical statement is given as

|2s - 7| is bigger than or equal to -1

The term "bigger than or equal" means greater than or equal to

In mathematics, the term greater than or equal to is represented as >=

So, we have the representation of the mathematical statement to be

|2s - 7| >= -1

From the question, we are not instructed to simplify the expression

This means that we leave the expression |2s - 7| >= -1 unsimplified

Hence, the mathematical statement as an expression is |2s - 7| >= -1

Step-by-step explanation:

First of all we look at the circles at the end.

Both are open circles, which indicates that -2 and 5 are not included.

Reading left to right, x is greater than -2 (remember, not greater than or equal to)

And x is less than 5 (not including 5)

The compound inequality is x > -2 and x < 5

Answer:

43 points

Step-by-step explanation:

let the score of cowboys is x

and giants make score 9 which is twice less than the cowboys score so

giants score will be = 2x -9

and packers scored 14 more than giants that is (2x - 9) + 14

now sum of their scores is equal to 81 it means:

x + (2x - 9) + (2x -9) + 14 = 81

x + 2x - 9 + 2x - 9 + 14 = 81

5x = 81 + 4

5x = 85

x = 17

packers scored =  (2x - 9) + 14

= 2 (17) -9 + 14

=38 + 5 = 43 points

Answer:

Answer:

a = 18

Step-by-step explanation:

We know from the table that our function must be y = 5x -2. We get this information by plugging in 13 = 5(3) - b and solving for b. Now that we have our function we plug in 4.

y = 5(4) -2

y = 20 - 2

y = 18
