Answer:

Last option: Square both sides of the equation in step 1 to eliminate the square root.

Step-by-step explanation:

The error is in the process of subtracting 3 from both sides, since +3 is inside the root.

In order to be able to operate with the terms that are inside the root, we need to eliminate the root, and for that we need to square both sides of the equal sign.

Help please. Need a simple explanation. ​
lbvjy [14]

Answer:

B) 20

Step-by-step explanation:

Each number in the equation needs to be a whole number, since you can't have 2.5 marbles or something like that.

2/5 of 16 is 6.4

2/5 of 20 is 8

2/5 of 21 is 8.4

2/5 of 26 is 10.4

Even though 20 is the only one that works, if you wanted to be sure it's right, just divide by three after subtracting 8 (the three remaining marbles.)

20-8=12

12÷3=4

The three remaining numbers would be equal and the amount of yellow numbers is a whole number. 20 is correct

Select the best equation needed to solve for x; then solve for x:
Lena [83]

Answer:

x=28 or C

Step-by-step explanation:

The graph shows a right angle which is 90 degrees

This means that the two angles seperated by line C added together will get 90 degrees.

That means the formula will be 2x+1+33=90

With that shown we can get rid of A and B

Next step is to add 33 and 1 together

This gives us 2x+34=90

Then we will move 34 to the other side by subtracting giving us 2x=90-34

Then we will subtract 90-34 which will get us 56

The equation is now 2x=56

The last step is to devide 2 from each side

This lets us get the answer x=28

Hope this helps!
