So, he runs 1.5 then adds 0.5 every day,
1.5
(1.5+0.5)+1.5=x
(2.0+0.5)+x=z
2.5+0.5+z=y
etc.
Why, they want to know the total distance he runs, so thats why you add x,y,z to the end, and you add 2.0+0.5 because he adds 0.5 every dat Plus the other day's miles jogged

u = 2 x + 1, d u = 2 d x, d x = d u / 2

- 9 / ( 2 + 1 )² - ( - 9 / ( 0 + 1 )² =
- 9 / 9 + 9 = - 1 + 9 =
8
Answer:
6
Step-by-step explanation:
2 times the difference of a number and 1 = 4 plus that number
In other to express the word problem Mathematically ; let the number = x
2(x - 1) = 4 + x
Expand
2x - 2 = 4 + x
Collect like terms
2x - x = 4 + 2
x = 6
Hence, the number is 6
Answer:
Inverse Property of Addition (Reason C)
Step-by-step explanation:
<u>Given:</u> 3(x – 4) = 33
<u>Prove: </u>x = 15
Statements Reasons
1. 3(x – 4) = 33 Given
2. 3x – 12 = 33 Distributive Property (Reason A)
3. 3x – 12 + 12 = 33 + 12 Addition Property of Equality (Reason B)
4. 3x + 0 = 45 Inverse Property of Addition (Reason C)
5. 3x = 45 Zero Addition Property (Reason D)
6. x = 15 Division Property of Equality
