We need to add like terms and distribute before we try to isolate X.
10x+3=8x+4-2
10x+3=8x+2

Now let's isolate x. We should start with subtracting 8x from both sides.
2x+3=2
Now, let's subtract 3 from both sides.
2x=-1
Now divide each side by 2.
X=-0.5
We now know x is -0.5, so let's check.
5(-0.5)+5(-0.5)+3=4[2(-0.5)+1]-2
-2.5-2.5+3=4(0)-2
-5+3=0-2
-2=-2

So, X= -0.5

ivolga24 [154]

Answer:

There is a 3/20 chance that a red plastic marble will be taken out on random.

Step-by-step explanation:

This is because there are 14 yellow marbles, and 6 red marbles. Along with this, half of the red marbles are made out of plastic. This leaves 3/6 of the red marbles made out of plastic. When combined with the yellow marbles, you'll add 14 to the denominator, since there are 14 yellow marbles. (Red + Yellow = Total Number Of Marbles) This leads to a total count of 3 marbles of the 20 total marbles, being red and made out of plastic.

NARA [144]

Answer:

157.1

Step-by-step explanation:

If you split the blue shape like in the picture, it shows that there is 1 large semicircle and 2 smaller ones.

The area of a semicircle is (pi×radius²)÷2

First, you would find out the area of the large semicircle by substituting in the numbers:

(3.142×10²)÷2=157.1

Then you would find out the area of the smaller semicircle:

The diameter of the semicircle is 10 so to find the radius you would half it.

(3.142×5²)÷2=39.275

To find the area of the whole shape, you would have to take away 39.275 and then add it back on so the answer would be 157.1

Hope this helps :)
