Answer:
Distributive property, Inverse Operation, and Division property of Equality
Step-by-step explanation:
Because 8•x is 8x and 8x3 is 24 so then the equation would be 8x-24=-40 then you have to add 24 on both sides to the 8x by itself and also get -16 which you would divide 8 on both sides to get x= -2
Answer:
0.48
Step-by-step explanation:
1x3/56 then multiply it by 9
1x3 is 3
3 x 9 = 27
27/56 this fraction cant be reduced so if you count it or put it in a calculator you'll get 0.482143
It is given in the question that B is in between C and D.
Therefore
![CB+ BD = CD](https://tex.z-dn.net/?f=CB%2B%20BD%20%3D%20CD)
Substituting the given values of CB,BD and CD, we will get
![4x-9+3x+5=17](https://tex.z-dn.net/?f=4x-9%2B3x%2B5%3D17)
Combining like terms, we will get
![7x-4=17](https://tex.z-dn.net/?f=7x-4%3D17)
Now we need to move 4 to the right side by adding 4 to both sides, that is
![7x = 21 \\ x=3](https://tex.z-dn.net/?f=7x%20%3D%2021%0A%5C%5C%0Ax%3D3)
