4x-2=90 wha is the answer to this problem?

Answers

Firstly, you want to get 4x alone, so to do this, you add 2 to both sides, as you always do the opposite operation.
This then becomes
4x=92
To get x alone, you then divide both sides by 4.
92/4=23
Therefore, x= 23
Hope this helps :)
Your goal is to get "x" by itself on one side

4x-2=90

Add +2 to each side

4x-2+2=90+2

4x=92

Divide 92 by 4

92÷4=23

x=23

What is the answer to dis equationn 6+9+6+9+6+9=???

Answers

Answer:

45

Step-by-step explanation:

6 × 3 = 18

9 × 3 = 27

18 + 27 = 45
Answer 45

9+ 9 = 18 + 9 = 27
6 + 6 = 12 + 6 = 18
27 + 18 = 45

How do you factor 8x+56?

Answers

If you mean how do you get x by it's you divide both sides by 8, to cancel out the multiplication between x and 8, meaning that it would end up being x=7, sorry if that didn't answer your question correctly. 
Divide 56 by eight (=7)
Divide 8x by eight (=X)
So you have X + 7
So I think it would be 1(x+7)

Which of the following tables of values represent ordered pairs for the function f(x) = 2x – 1?x 3 6 9 12
f(x) 6 12 18 24

x 2 4 6 8
f(x) 5 9 13 17

x 1 2 3 4
f(x) 1 3 13 17

x 0 4 8 12
f(x) -1 7 15 23

Answers

The answer is A because x = 1/2 meaning that X is always going to be half of Y

Final answer:

The correct table of values that represents the function f(x) = 2x − 1 for the given values of x is the one with x values 0, 4, 8, 12 and corresponding f(x) values of -1, 7, 15, 23.

Explanation:

To determine which table of values represents ordered pairs for the function f(x) = 2x − 1, we need to check each pair of x and f(x) to see if they satisfy the equation. Let's examine each table:

  • x = 3; f(x) should be 2(3) − 1 = 5, but the table shows 6.
  • x = 2; f(x) should be 2(2) − 1 = 3, and the table shows 5 which also incorrect.
  • x = 1; f(x) should be 2(1) − 1 = 1, but the table shows 1 which is correct. Let's check the rest: for x = 2, f(x) = 3, which matches the table. However, for x = 3, f(x) should be 5, not 13 as listed in the table. So, this table is also incorrect.
  • x = 0; f(x) should be 2(0) − 1 = -1, which matches the table. For x = 4, f(x) = 7 confirms the table. The pairs for x = 8 and x = 12 also match the function. Therefore, the last table correctly represents the function f(x) = 2x − 1 for the given values of x.

The correct table of values for the function f(x) = 2x − 1 is the one that correctly corresponds for all x's:

  • x: 0 4 8 12
  • f(x): -1 7 15 23

The volume V of a rectangular prism with length l, width w, and height h is v equals l times w times h. What is the width of a rectangular prism with volume 450 cubic inches, length 20 inches, and height 7.5 inches?

Answers

Answer:

The answer is 3 inch

Step-by-step explanation:

To start off, the equation you want to use the formula V=whl

Next, you simply plug in the values you already know, so you have 450=w*20*7.5

After you do that you multiply 20 times 7.5 to get which is 150, which leaves you with 450= w *150 to solve for w, you need to isolate it. To do that you divide 450 by 150. You are left with the answer of 3.
450=w•20•7.5
^
450= w150
——- ———
150. 150

3=w
