Answer:
5 terms, the coefficient of x is 1.
Step-by-step explanation:
A term is a value/number used in an equation. That means 5², 6, 2, 20, and 4 are terms. For the next one, if a variable has no number next to it, that means the coefficient is 1.
Suppose x grams of 8% solution should be mixed to make 100 g of 3% solution.
here we shall have:
the amount of 3% solution in the 100 g will be:
3/100*100=3 grams
the the equation will be, 8% of what quantity becomes 3g?
(8/100)*x=3
hence solving for x we shall have:
0.08x=3
x=3/0.08
x= 37.8 grams
The implication of this is that, when you have 37.5 grams of 8% solution, that will contain 3 of pure chemical and hence when you add more solvent on top of 37.5 g until you reach 100g, that will be 3% solution.
Answer:
a = 2
Step-by-step explanation:
Multiply equation by 2a to get rid of denominators.
10 + a = 12
a = 2
