The equation -21t - 4 = 10 - 2t has only one solution
<u>Solution:</u>
Given, equation is – 21t – 4 = 10 – 2t
We have to find how many solutions does the above given equation have
Now, let us solve the given equation to find the number of solutions it has.
Then, - 21t – 4 = 10 – 2t
Taking like terms to one side of the equation we get,
- 21t + 2t = 10 + 4
here we can see only one value of t.
Hence, the given equation has only one solution.
Answer:
1. 4.5 g
2. 56.25 g
Step-by-step explanation:
3 % substance solution means :
3 g of dry substance is present in 100 g of solution.
By unitary method:
The weight of dry substance in 1 g of solution =
The weight of dry substance in 150 g of solution =
Let the weight of solution be w.
8 % solution contains 8 g dry substance in 100 g.
We have to find the weight of the solution(w) which contains 4.5 g of dry substance.
