Answers

Answer:

C) -4   1

   -2   -7

Step-by-step explanation:

I got it right on Edge 2021

The value of x in expression is,

⇒ x = [- 4, 1, - 2, - 7]

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

The expression is,

[-1, -2, 4, 8] + x = [-5,- 1, 2, 1]

Now, We can simplify as;

x = [- 5, - 1, 2, 1] - [ - 1, - 2, 4, 8]

x = [- 4, 1, - 2, - 7]

Thus, The value of x in expression is,

⇒ x = [- 4, 1, - 2, - 7]

3 Leah surveyed the 35 members of her class to find out their favorite color. She listed this information in the form of a table, as shown here. Favorite Colors Colors Number of Students Choosing Colors Blue 14 Green 5 Yellow 7 Red 3 Orange 1 Maroon 5 Based on this information which is the best estimate of the number of people choosing red as a favorite color from a group of 175 people? (whoever shows work gets brainliest)​

Answers

Answer:

15.

Step-by-step explanation:

If you add all of the marbles you will get 35 as the total.

Since there are 175 students, we can divided 35 by 175 and safely assume that for every marble, 5 people have chosen it.

This means that there are 3 red marbles, or that 15 people have chosen that marble.

Two numbers are missing from this table. how can the missing numbers be found.

A swimming pool is in the shape of a rectangular prism. The pool is 30 feet long, 16 feet wide, and 6 feet deep. James stretched a hose straight from a top corner of the pool to the bottom corner farthest away. What is the length of the hose from the top corner to the bottom corner farthest away? ​

Answers

Answer:

About 34.5 which you can round to 35

Step-by-step explanation:

First you find the hypotenuse of 30 and 16 which is 34

Then the hypotenuse of 34 and 6 which is about 34.5

The length of the hose from the top corner to the bottom corner farthest away will be 34.5 feet

What is a Rectangular Prism?

A rectangular prism is a 3-D figure, which has 6 faces, 8 vertices and 12 edges. All of the faces will be in rectangular shape.

Rectangular prism has three dimensions, namely, length, width and height.

Length of the swimming pool = 30 feet

Width of the swimming pool = 16 feet

Height of the swimming pool = 6 feet

We have to find the length of the hose from the top corner to the bottom corner farthest away.

For that first we have to find the length of the hypotenuse of the triangle with base = 30 feet and altitude = 16 feet

= √(30² + 16²)

= 34 feet

Now, we have to find the hypotenuse of the triangle with base = 34 feet and altitude = 6 feet.

= √(34² + 6²)

= 34.5 feet

Hence the length of the hose from the top corner to the bottom corner farthest away is 34.5 feet.

Lucy separates a number of paintbrushes, x, into 2 equally sized groups. She claims that this is the same as making a group 1/2 the size of his original group. Create an equation that models Lucy's claim.

Answers

Answer:

x/2 = 1/2x

Step-by-step explanation:

# of paintbrushes/ 2 piles = 1/2 # of paintbrushes

Answer:

x/2

Step-by-step explanation:

Since Lucy is taking the paintbrushes, x, and splitting them into 2 equally sized groups we can assume that this IS 1/2 the size of the original group.

We can show this claim by simply doing this equation: x/2, since she is splitting them into 2 groups that are equally sized, we are just dividing x by two.
