Answer:
d = 3
Step-by-step explanation:
3.5d + 6.25 = 1 + 5.25d
5.25d - 3.5d = 6.25 - 1
1.75d = 5.25
d = 5.25 ÷ 1.75 = 3
Answer B Distributive Property
Answer:
n= -3 and n= -6
Step-by-step explanation:
We need to solve this equation to find the value of n.
Rearranging:
This is a quadratic equation and we can solve by using factorization method.
We need to make factors of 18n^2 such that their sum is equal to 9n.
So solving,
There are 60 minutes in a hour, 24 hours I'm a day, so 24 multiplied by 60 is 1,440, then multiplied by 365, the days in a year, getting 525,600 burgers in a year, divide 1 billion by that number, rounding that up gets 1,903 years
1) add, equal
2) multiply, equal
3) subtract, equal
