Can you solve 2(2x-1)+2x=6(x-1) for me? I am not sure how. And how many solutions are there?

Answers

Answer 1

Answer: 2(2x-1)+2x = 6(x - 1)

4x - 2 + 2x = 6x - 6

6x - 2 = 6x - 6

Subtract both sides by 6x and we have -2=-6, which is false equation, therefore there is no solution.

Answer:

18° and 72°

Step-by-step explanation:

Complimentary angles form 90°

We have an angle (x) 4 times larger than the other (y).

Well actually, a system of equations isn't required, so forget about x and y, just divide 90 by 5. This gives you 18, one of the angle's measurements is 18°. Multiply 18 by 4 and get 72. The other angle's measurement is 72°.

How does your answer help you solve a division equation such as x/7 =2 ?

Answers

dunno

I can solve it though
x/7=2
multiply both sides by 7
x/7 times 7/1=2 times 7
7x/7 =14
7/7 times x/1=14
1 times x=14
x=14

answer is 14

hmm, maybe multiply bottom number by the one on the other side of the equal sign

You plug in your answer for x and solve it to see if it = 2. So x=14. You plug it back into the equation. 14/7=2
2=2
Your answer is correct.

−4x + y = 6

assuming x=x and y=y in both equations

Which is greater 0.55 or 2/5 or 0.46

Answers

The greatest among the given numbers 0.55 or 2/5 or 0.46 is: 0.55

How to find the greatest number?

There are different inequalities such as:

Greater than

Less than

Greater than or equal to

Less than or equal to

Now, we want to find the greatest among 0.55 or 2/5 or 0.46.

Let us convert 2/5 to decimal to get 0.4

Thus we can say that the greatest is 0.55
