How many solutions can be found for the equation 4x - 8 - 4x = 9? (4 points)
оа
Zero
Ob
One
Ос
Two
Od
Infinitely many

Answers

Answer:

A. Zero

Step-by-step explanation:

This would have no solution because when you try to solve the equation and simplify, the 4x's cancel out, leaving no variable and making the equation reduce to: -8=9 which is false, and therefore, this has no solution.

A line parallel to y=1/3 x+2

Answers

Answer:

y = 1/3x

Step-by-step explanation:

If you use the form y = mx + b, all you need to create a parallel line is to have the same slope. So, we can just disregard b and write an equation with a slope of 1/3. You can add or subtract any number to that if you want.

DeShawn and Totsakan are selling wrapping paper for a school fundraiser. Customers can buy rolls of plain wrapping paper and rolls of shiny wrapping paper. DeShawn sold 12 rolls of plain wrapping paper and 1 roll of shiny wrapping paper for a total of $59 . Totsakan sold 6 rolls of plain wrapping paper and 8 rolls of shiny wrapping paper for a total of $112. Find the cost each of the rolls of plain wrapping paper and one roll of shiny wrapping paper .

Answers

9514 1404 393

Answer:

plain: $4shiny: $11

Step-by-step explanation:

Let p and s represent the costs of plain and shiny rolls of paper, respectively. The given sales let us write two equations in these two unknowns.

  12p +1s = 59 . . . . . DeShawn's sale

  6p +8s = 112 . . . . . Tatsakan's sale

Multiplying the second equation by 2 and subtracting the first, we have ...

  2(6p +8s) -(12p +s) = 2(112) -(59)

  15s = 165 . . . . . . . . . . . . . . . . . . . . . simplify

  s = 11 . . . . . . . divide by 15

Substitute into the second equation to find p.

  6p +8(11) = 112

  6p = 24 . . . . . . . . subtract 88

  p = 4 . . . . . . . . . . .divide by 6

A plain roll costs $4; a shiny roll costs $11.

Answers

180 - 81 = 99

the answer is 99!
The answer would be 99 degrees!
here is an explanation to help you understand:
the angles 81 degrees and b are supplementary angles. Supplementary angles mean that two angles have the sum of 180 degrees so you would need to find the x when you have a given already.
do an equation like this:
x + 81 = 180
here is how to answer the equation:
x + 81 - 81 = 180 - 81
x = 99

Here you only need to subtract 81 from both sides. in simple terms, do 180 minus the measure given.

The measure of the value of x is 11

Properties of a parallelogram

One of the properties of a parallelogram is that the diagonals of a parallelogram bisect each other.

Given the diagonals with the sides x + 4 and 2x-7, equating both expresions will give:

x + 4 = 2x - 7

x - 2x = -7 - 4

-x = -11

x = 11

Hene the measure of the value of x is 11

1. A right angled triangle has two shorter sides and one is twice as long as the other. The hypotenuse is 25 cm long. What are the lengths of the shorter sides?

Answers

Step-by-step explanation:

The hypotenuse of a right-angled triangle = 25 cm

One side is twice as long as the other.

Let the other side is x.

First side = 2x

Using Pythagoras theorem to find the lengths of the shorter sides.

[tex]x^2+(2x)^2=25^2\\\\x^2+4x^2=625\\\\5x^2=625\\\\x^2=125\\\\x=11.18\ cm[/tex]

So, the other side = 11.18 cm

First side = 2(11.18) = 22.36 cm

So, the lengths of the shorter sides are 11.18 cm and 22.36 cm.

4÷16/17=

Answers

Step-by-step explanation:

Turn 4 into 4/1. Then switch 4/1 or 16/17 because I don't know which to switch. If you don't know what I'm talking about, when you switch 4/1 or 16/17, you'll get 1/4 or 17/16. Then you multiply 1/4 × 16/17 or 4/1 × 17/16. You multiply across, like this, 1 × 16 and 4× 17 Same thing with 4/1 × 17/16 but backwards (4×17 and 1×16). Do both equation (4/1 × 17/16 and 1/4 × 16/17) by yourself, then simplest it. Example: 2/4 = 1/2. You divide 2/4 by two, 2÷2 for the numerator and 4÷2 for the denominator. That how you simply.
