thank you.

Answers

Answer 1

The amount of water that should be added to 5 gallons of 50% acid to get 20% solution is 7.5 gallons.

Word problems in mathematics requires crucial understanding and mathematical knowledge to be able to solve real life cases.

From the information given:

Let consider (x) to be the amount of water to be added 5 gallons of 50% acid solution will be = 5 × 0.5 = 2.5 gallons of acid in 50% solution.

The amount of water to be added can computed by using the relation:

[tex]\mathbf{\dfrac{2.5}{x+5} = 20\%}[/tex]

[tex]\mathbf{2.5= 0.2(x+5)}[/tex]

2.5 = 0.2x + 1

2.5 - 1 = 0.2x

1.5 = 0.2x

x = 1.5/0.2

x = 7.5

Paul has thirteen coins in his piggy bank. Some of the coins are quarters, some are nickels, and he has a total of $3.55. Which system of equations can be used to determine how many quarters, x, and how many nickels, y, he has?

A.
x + y = 13
0.25x + 0.5y = 3.55

B.
x + y = 13
0.25x + 0.05y = 3.55

C.
x + y = 13
25x + 5y = 3.55

D.
x + y = 3.55
0.25x + 0.05y = 13

Answers

Answer:

The answer is B

Step-by-step explanation:

you know that x is quarters which is .25 and you know that y is nickels which is .05

there are a total of 13 coins in the bank so x+y = 13

you also know that the 13 coins = 3.55

so plug in all that you know and the problem is

0.25x + 0.05y = 3.55

Multiplying by 1 and dividing by one leads to the same conclusion. They both wind up to 4. The only one is B) because 4x0 is 0 and that isn't 4, so it changes value.
