Answer:
a=4
Step-by-step explanation:
8x-8+3ax=5ax-2a
Get all the terms with a on the right side
Subtract 3ax from each side
8x-8+3ax-3ax=5ax-3ax-2a
8x-8 = 2ax -2a
Factor out an 8 on the left and 2a on the right
8(x-1) = 2a*(x-1)
Divide by (x-1) on both sides
8(x-1)/(x-1) = 2a*(x-1)/(x-1)
8 = 2a
Divide by 2
8/2 =2a/2
4 =a
Answer:
x<-3 or x>-1
Step by step explanation:
Start with -5x>15. To get x by itself, we have to divide each side by -5. When we do that we get x<-3. (Don't forget to flip the sign when dealing with negative · and ÷.) Now answer the second equation. x-5>-6 To get x by itself, add 5 to both sides to get x>-1. Now we have x<3 or x>-1.
(-10) + 14 + 25 + (-16) Add 14 and 25
(-10) + 39 + (-16) Change 39 + (-10) to 39 - 10
(-10) + 39 - 16 Subtract 16 from 39
(-10) + 23 Change (-10) + 23 to 23 - 10
23 - 10 Subtract 10 from 23
13
*Remember, you can rearrange expressions like this as long as each number keeps its sign. Notice that (-10) had its negative sign the whole time, even though we moved it around.
Answer:
The answer is -11
Step-by-step explanation:
subtract 6 from both sides.
divide both sides by the negative 4
Simplify 44/-4x
which gives you x= -11
Answer:
Step-by-step explanation:
The given formula is:
c=5d+4w/2w
We need to find d.
Multiply 2w on both sides, we get
c x 2w= 5d+4w/2w x 2w
2cw=5d+4w
Adding -4w on both sides, we get
2cw-4w=5d+4w-4w.
2cw-4w=5d
2w(c-2)=5d
Dividing by 5, we get
2w(c-2)/5 = 5d/5
2w(c-2)/5 = d
Hence the required formula with subject d is
