Here is my question: 2n + 4 = 4n + 1 - 2n
(keep in mid it's either an infinite solution, 0, or 1)
Answer:
0 solutions
Step-by-step explanation:
2n + 4 = 4n + 1 - 2n
↑
first combine like terms (right side)
2n + 4 = 2n + 1
but this part you can tell that there's 0 solutions, because both sides have 2n/ same variable with same number.
No Solution.
Once you combine the like terms 4n-2n of the second equation you end up with
2n+4 = 2n+1.
There is no value of n that results in a true equation.
Maria had 4 full cement, blocks & one that was 5/9 the normal size, If each full block weight 3 8/9 pounds, What is the Weight blocks maria has? (20 POINTS!)
The total Weight blocks maria has is 15.2 pounds.
What is Fraction?A fraction represents a part of a whole.
Given that Maria had 4 full cement, blocks & one that was 5/9 the normal size.
Each full block weight [tex]3\frac{8}{9}[/tex] pounds
We need to find the Weight blocks maria has
Let us convert the mixed faction to improper fraction
35/9 = [tex]3\frac{8}{9}[/tex]
As there are 4 full cement, blocks
So multiply 4 with [tex]3\frac{8}{9}[/tex]
4×35/9
4×3.8
15.2
Hence, the total Weight blocks maria has is 15.2 pounds.
