This past Sunday, the Giants scored 9 points less than twice the Cowboys. The Packers scored 14 more points than the Giants. If the teams scored 81 total points, find the number of points scored by the packers

Answers

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

The last option: x > -2 and x < 5

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

What are the x and y-intercepts of the line described by the equation?

2x+4y=12.4
Question 2 options:

x-intercept = -6.2

y-intercept = -3.1


x-intercept = -3.1

y-intercept = -6.2


x-intercept = 6.2

y-intercept = 3.1


x-intercept = 3.1

y-intercept = 6.2



Please help

Answers

Answer:

x-intercept = 6.2 , y-intercept = 3.1

Step-by-step explanation:

First turn 2x + 4y = 12.4 to slope-intercept form (y = mx + b) where m is slope and b is y-intercept.

Subtract 2x on both sides to move it to the other side, and get 4y by its self. Now it looks like 4y = -2x + 12.4 (since 2x and 12.4 aren't like terms, you wouldn't combine them).

Next, divide 4 on both side to get rid of it, and to get y by its self. Now you'll have

y = -2/4 x + 3.1 (since 12.4 can be divided by 4, that's how you get 3.1). You can already tell, just by looking at

y = -2/4 x + 3.1 , that the y-intercept is 3.1

Now we graph, to find out what the x-intercept is. I did it for you above.⤴⤴⤴

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).

The area of a curved surface of a cylinder is 4400cm² and the circumference of its base 110cm. Find the height of the cylinder.​

Answers

Step-by-step explanation:

Area of a curved surface of a cylinder = 4400 cm².

The circumference of its base = 110 cm.

As we know that,

Formula of : circumference of base = 2πr.

→ 2πr = 110.

→ πr = 55.

Formula of : Curved surface area of cylinder = 2πrh.

→ 2πrh = 4400.

Put the value of πr = 55 in the equation, we get.

→ 2(55)h = 4400.

→ 110h = 4400.

→ h = 40 cm.

Height of cylinder = 40 cm.

Answer:

<= means greater than or equal to

Step-by-step explanation:

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

How to determine the minimum number of hours?

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

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

Answers

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

What are inequality expressions?

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

How to represent the statement as an expression?

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

Answers

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.
