X + 3 * 21 = 12
x + 63 = 12
x = 12-63
x = -51
The wording was a little odd, but I hope this is what you’re looking for!

Marcel made an error when he used the distributive property to write an equivalent
natima [27]

Answer: Upper left corner

Explanation:

The error happens in step 2. Notice that x is <u>not</u> part of the second term 16, so there's no way to factor x from it unless you want a fraction to result.

The second step should be 8(4x-2)

Another way to factor is to say 16(2x-1)

Need help doing this, show steps if you could
Anna71 [15]

Answer:

p = (0.5 , 5)

Step-by-step explanation:

D(-6 ,4)    E(7 ,6)

For the line FP  to be a median, the point p must have the intermediate value at x and at y between points D and E

p = (Dx + Ex)/2 , (Dy + Ey)/2

p = (-6 + 7)/2 , (4 + 6)/2

p = 1/2 , 10/2

p = (0.5 , 5)

This is because for a medium to be the point p has to be right in the middle of the other 2 vertices

Paige used 1 1/2 cups of flour and 1/4 cup of butter to make 12 muffins. How much flour and butter would palat
yanalaym [24]

Answer:

D

Step-by-step explanation:

To turn the fraction of 1 1/2 to decimal would be : 1.50 add fifty percent because you have to add 6 to 12 and six is half, so you add half. Half of 150 is 75 so add them you get 225 and as a fraction, that's 2 1/4. Already you have the first part done. Since there is only one answer with 2 1/3 your answer has to be D.
