X will stand for every extra book sold
880 = 4x + 500
subtract 500 from both sides
380 = 4x
divide both sides by 4
x = 95
they sold 95 books
854 and 13 x this statment is true
Explanation:
1. (Given)
2. Multiplication property of equality (multiplication by 2)
3. Distributive property
4. (Addition property ...)
5. Addition property of equality (6x was added)
6. Division property of equality (equation was divided by 13)
Answer:
21
Step-by-step explanation:
There are 2 halfs in 1 number.
Lets start with your whole number: 10
You double 10 because there are two halfs in each whole number making it equal 20.
Now you have 3/4
There would be 1 half in this number because it's a fraction and not a whole number.
You would be left over with 1/4
Your answer is 21
Hope this helps! Goodluck
<u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u><u>:</u><u> </u>√15 units
Step-by-step explanation:
Let (6,1) be (x^1,y^1) and (1,-9) be (x^2,y^2) .
As we know ,
Distance(D) = √(x^1-x^2) +(y^1-y^2)
Now,
D= √(x^1-x^2) +(y^1-y^2)
= √(6-1) +(1+9)
= √5+10
= √15 units
: Therefore the distance between (6,1) and (1,-9) is √15 units.
