Answer:
the answer is C......
Step-by-step explanation:
!!!!!!!!!!!
2.5, because 6 2/3 - 4 1/6....
First, find the most common denominator! Which is 6.
Multiply the bottom term to 2 times. (To get 6.) Now do the same for the top! So 6 4/6 - 4 1/6
Second, you subtract!
2 3/6
Third, if your teacher has ever taught you this or not....
If she did: Simply 2 3/6 into 2 1/2!
Finally,
2 1/2 can be 2.5, 2 3/6, or just 2 1/2!
Answer:
x = 4.25
Step-by-step explanation:
1. distribue the -5 on the left side of the equal sign by multiplying it with 2x and -9 inside the brackets. Do the same with the negative sign and the -6x and 10 in the brackets on the right side of the equation. this should make:
17 - 10x + 45 = 6x - 10 + 4
2. Combine like terms on both sides of the equal sign. Add 17 and 45, and add -10 and 4 to make:
62 - 10x = 6x - 6
3. Bring like terms onto the same side. You can either bring the 62 to -6, which would make 62 negative, or bring -6 to 62, making the 6 positive. Do the same with -10x and 6x. It should make:
68 = 16x OR -68 = -16x
4. Divide both sides by 16 or -16, depending on which option you went with.
68/16 = 16x/16 OR -68/-16 = -16x/-16
This gives:
4.25 = x
