Do anyone know how to do algebra 1 ixl . I really need help .

Answer:2

Step-by-step explanation:

You need to remember these 3 rules when working with multiplication:

Negative number x Negative number = positive number

Negative number x Positive number = Negative number

Positive Number x Positive Number = Positive Number

With that in mind, we see in this equation we are multiplying negative number x positive number = negative number

And we also know 7*2=14 so we know A = 2 and we also know (since A is a positive number) 2 will be postitive:

So the equation will look like this:

-7 x 2 = -14

Therefore A = 2

Hope this helps :D

3:5 and 1:3 is not proportional

6:15 and 2:5 is Proportional

2:3 and 4:1 is not proportional

The sum of the angle measures is 180 degrees

  -->[tex](3x + 28)+(5x + 52) +(2x -10) = 180\\10x + 70 = 180\\10x = 110\\x = 11[/tex]

Since x= 11, angle c = 2(11) - 10= 12

Hope that helps!

So

Answer:

72 sq ft

Step-by-step explanation:

A square room means ecah side is equal. so 12*12= 144.

12 times 6 (for the height)= 72 sq ft

Answer:

72 square feet

Step-by-step explanation:

if the area of the floor is 144 and square, that means that the sides are the same length. 12 * 12 = 144 so the length is 12.

the height of the room is 6 so you multiply 12 and 6 and you get 72

Answer:

To have a right triangle, the side lengths should make Pythagorean theorem true

Since the hypotenuse is always the longest side of a triangle, the biggest number will be c

Set the rest two numbers as a and b

Use a^2 + b^2 = c^2 to plug in the numbers

If you get true equation, meaning you have the same number on the left and right sides of equation, then it is going to create a right triangle

Answer:

The picture is too blurry to see, so let me explain how you find the answer for yourself...

Step-by-step explanation:

Basically, time is the y-axis (up and down), and # of rebounds is the x-axis (left and right). The question asks for rebounds made in 15 minutes, so first find the 15 mark on the left of the graph. Trace that line across the graph to the right (use ur finger if you have to) until you hit a dot. Trace the line that the dot is on down to the bottom of the graph. The number you hit will be your answer (# of rebounds).

Answer:

58

Step-by-step explanation:

Lmk if its correct :)

When it comes to right triangles, there's one extremely important equation that you'll have to use almost every single time you come across one: the Pythagorean Theorem.

[tex]a^{2} + b^{2} = c^{2}[/tex]... Does that equation ring any bells? This equation is utilized to solve for any of the sides of a right triangle, given that you know the values of two of the sides. in a right triangle, there are three sides - one of which is known as a hypotenuse (the longest side of a right triangle). Variables a and b represent the lengths of the non-hypotenuse sides (basically, the two smaller sides, the ones that form a right angle). There's no special rule to which side is designated a and which is designated b, so don't worry about trying to figure out which side should be labeled which. Variable c represents the length of the hypotenuse.

Now, how can we apply the Pythagorean Theorem to this question? We are given the values of the two legs of the triangle, 1 m and [tex]\sqrt{15}[/tex] m. Since we are prompted to solve for the length of the hypotenuse, we will use the Pythagorean Theorem and solve for c, the variable for the length of the hypotenuse.

[tex]c^{2} = a^{2} + b^{2}[/tex]

c = [tex]\sqrt{a^{2} + b^{2} }[/tex]

(We square root both sides in order to isolate c. Now, let's plug in the values we were given. As we learned earlier, it doesn't matter which leg is a or b)
c = [tex]\sqrt{1^{2} + \sqrt{15}^{2} }[/tex]

c = [tex]\sqrt{1 + 15}[/tex]

c = [tex]\sqrt{16}[/tex]

c = 4 (m)

The length of the hypotenuse is 4 meters.

And we're done! Though I wrote a lot, the equation is fairly simple and will come extremely handy any time you're faced with questions like these. If you have any questions about anything I wrote here or you need clarification on anything, let me know!

5 feet

15 divided by 3 is 5

Area is base x height so 3 x 5 is 15

Answer:

C-5 feet

Step-by-step explanation:

If the area is 15, and the width is 3, we need to find the length with the info we have. And we know, to find the area, we need to multiply the length and the width. What number times 3 can get us to 15? Let's find out by dividing.

15/3=5

How to check? Use inverse operations:

3*5=15

I have included a screenshot of my test. It shows I got it wrong but has the correct answer as well. Good luck I hope my mistakes help someone.

Step-by-step explanation:

The area of the rectangular picture frame that is 5/6 feet long and [tex]1\frac{2}{3}[/tex] feet wide is  [tex]1\frac{7}{18}[/tex] ft²

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Given that, Jackie bought a rectangular picture frame that is 5/6 feet long and [tex]1\frac{2}{3}[/tex] feet wide.

We need to find its area,

We know that, the area of the rectangle = length × width

Here,

Length = 5/6 ft

Width =  [tex]1\frac{2}{3}[/tex] ft

Area =  [tex]1\frac{2}{3}[/tex]  × 5/6

= 5/3 × 5/6

= 25/18

= [tex]1\frac{7}{18}[/tex] ft²

Hence, the area of the rectangular picture frame that is 5/6 feet long and [tex]1\frac{2}{3}[/tex] feet wide is  [tex]1\frac{7}{18}[/tex] ft²

Answer:

  695 revolutions

Step-by-step explanation:

Finding the number of revolutions is basically a units conversion problem. You want to translate miles to revolutions. We can do this by way of feet and inches. The circumference of the wheel is pi times the diameter.

  1 mi = (1 mi) × (5280 ft)/(1 mi) × (12 in)/(1 ft) / (29π in)/(1 rev)

  = (1·5280·12·1)/(1·1·29π) = (63360/(29π)) rev ≈ 695.45 rev

About 695 revolutions will be needed to make the bike travel 1 mile.

The expression which is stated that three more than a number squared is n² + 3. Then the correct option is C.

Answer: 5 divided by 1/2 is 10

Step-by-step explanation:

5 x (1/2) = 10/1 = 10

Multiplying the first fraction by the reciprocal value of the second fraction is the same as dividing two fractions. The first step is to get the reciprocal of the second fraction (reverse the numerator and denominator, reciprocal of 1/ 2 is 2/ 1 ). Multiply the two numerators after that. Then add the two denominators together.

To put it another way, five divided by one-half equals 10.
