So in math class we are doing Simplifying Algebraic Expressions or at least that is what the lesson is called but what is 7x +7. I was just wondering because it is a step in my question and im not sure if i could just add them normally or not.

Answers

Answer 1
no you can’t add them, but you can do this: 7x+7 =0
-7 -7
7=7x
/7 /7
1=x
Answer 2
No, you can’t because, to simply algebraic expressions the numbers or letters or coefficients need to be the same. 7x have a number with a letter but, the +7 only have the number. In other words, the letters and/or the exponents (in this one there’s no exponent but I’m just putting an example) need to be the same in order to combine them

I NEED HELP FAST ITS FOR A TEST (no links pls)
Part A: Explain why x = 6 makes 5x − 6 ≤ 24 true but not 5x − 6 < 24. (5 points)

Part B: What value from the set {5, 6, 7, 8, 9} makes the equation 6x + 4 = 34 true? Show your work.

Answers

Answer:

I dont know about A but the answer for B is below

Step-by-step explanation:

6x + 4 = 34 = (6x5) + 4 = 34

Answer:

Seem you are doing the same test I did! Module 7 part 2?

Anyway!

Part A: If we work through the equation 5x - 6 and substitute 6 for x then we have (5*6) - 6 = 30 - 6  = 24.

Therefore, 5x − 6 ≤ 24 is true since it means that it is equal to or less than 24.

And 5x − 6 < 24 is wrong since the equation equals 24 and is not less than 24.

Part B:

6x + 4 = 34

6x5 = 30

30+4=34

To verify: (6*5) + 4 = 34. The answer is five.

Explanation: to find the volume of the cone you would have to use the formula:

1/3* pi* r^2* h
If the dimensions are to be plugged in the formula would then be

1/3* 3.14* 4^2 * 12

Therefor the volume of the cone is 201.06 in^3

Moving on to the cylinder, the formula used would be

V=Bh

To find B the formula used would be

B= pi* r^2

Plugged in the formula would turn unto

B= 3.14* 3^2

The volume of the cylinder is 226.19

When subtracted, the area if the cylinder is about 25 cubic inches less than the cone, so the answer is D.

Answer:

a)  56 beads

b)  8 beads

Step-by-step explanation:

12 beads take 3 inches so yes 12/3 =4 per inch

but then the necklace is 14 in long so 4 *14=56 beads

if you take off one ince per side you would take of 4 beads per side so 4*2=8 beads

Answer:864m^2

Step-by-step explanation:

18*18=324

18*30=540

540+324=864

Answer:

684 m.

Step-by-step explanation:

First you divide the shape into one rectangle and one square. You first multiply 18 x 18 for the square to find the area, which equals to 324. Then you do 18 x 30, as the sides are equal. this equals to 540. Now, you add up 324 and 540. You will get the total of 684.

HELP! Two right rectangular prisms are shown below. If each prism is packed with small cubes of side length 1/4 inch how many more cubes are in prism 2


A. 42 Cubes B. 48 Cubes

C. 510 Cubes D. 720 Cubes

Answers

Answer:

First find the volume of the two rectangular prisms using the formula:

V = l · w · h

Where 'l' represents the length, 'w' the width, and 'h' the height.

Now let's find the volume of Prism 1;

V = l · w · h

V = 7/4 · 3/2 · 5/4

V = (7/4 · 3/2) · 5/4

V = 21/8 · 5/4

V = 105/32 cubic inches.

Now let's find the volume of Prism 2;

V = l · w · h

V = 5/2 · 9/4 · 2

V = (5/2 · 9/4) · 2

V = 45/8 · 2/1(make 2 to 2/1 because it makes it a bit easier)

V = 90/8 cubic inches.

Now let's find how many cubes can fit into each of these prisms.

But first, we need to find out the volume of one cube.

Remember, all sides to a cube are equal.

Using the formula, V = l · w · h;

1/4 · 1/4 · 1/4

= 1/64 cubic inches is the volume of one cube.

Now we find how many cubes can fit inside each of these prisms.

Prism 1:

105/32(volume for this prism) ÷ 1/64(volume of one cube)

= 210 cubes can fit inside prism one.

Prism 2:

90/8(volume for this prism) ÷ 1/64(volume of one cube)

= 720 cubes can fit inside prism two.

Finally, let's calculate their difference:-

720 - 210

= 510 cubes.

Hence, prism 2 can hold 510 more cubes than prism 1.
