q minus 22 = 24: Add 22 to both sides. The answer is 46.

2. How many solutions to the equation 2x +2 = 2(x+3)
O 1 solution
O Infinitely many solutions
O No solution

Answers

Answer:

O No solution

Step-by-step explanation:

2x +2 = 2(x+3)

Distributer the 2 on the right side.

2x + 2 = 2x + 6

Subtract 2x from both sides.

2 = 6

2 = 6 is a false statement.

Since we did two legal steps to solve the equation, and we ended up with a false statement, that means this equation has no solution.

Answer: O No solution

what is the solution to the system y= 2x-3 y= -x+3

Answers

You would have to step up your problem like this 2x-3=-x+3, then you add -x to both sides. So, the problem will look like this 3x-3=3 then add to both sides. The ending problem will look like this 3x=6 then divide 3 to both sides then your answer is 2! Hopefully this is correct!

which one is greater 3/40 or 7.5%

Answers

Answer: they are equal

To write a fraction as a percentage the easiest method is if we can change the denominator to 100.

#3/40 xx2.5/2.5 = 7.5/100 = 7.5%#

In many cases that method does not work,

so we can also do this by #xx 100%#

#3/40 xx 100%#

=#7.5%#

Which rule describes the composition of transformations that maps figure ABCDE to figure A" B" C" D" E"?​

Answers

Answer:

It would be the fourth choice.

Step-by-step explanation:

To get ABCDE to A'B'C'D'E', you need to reflect the shape across line M. Then to go from A'B'C'D'E' to A''B''C''D''E'', you need to rotate about point C 180⁰.

It was first reflected across the x axis which would be line m. And since point c is the same place for the two bottom images , after the reflection it was rotated on point c.

The answer should be the 4th choice

0.8 = 0.5x

Solve for x

Please show steps thanks so much

Answers

If I’m not mistaken, to solve for x you have to get it by itself so you need to divide 0.5 from both sides:

0.8/ 0.5 = 0.5x/ 0.5

Cross out the 0.5’s on the right because they cancel out and you will end up with:

0.8/ 0.5 = x

All you have to do then is divide 0.8 by 0.5 and you get:

1.6 = x
