Harry solves the equation 1/3t = 15. He says the solution is 30. Is his answer correct? Fill in the blanks to explain how Harry

aksik [14]

Harry can first substitute 30 for t

He can then multiply $\frac{1}{3}$ by 30 to get a product of 10

Since, 10 is not equal to 15, Harry's solution is not correct.

<em><u>Solution:</u></em>

Given that,

Harry solves the equation:

$\frac{1}{3}t = 15$

He says the solution is 30

We have to check if his answer is correct or not

<em><u>Fill in the blanks to explain how Harry can check whether his solution is correct</u></em>

Harry can first substitute 30 for t

$\frac{1}{3} \times 30 = 15$

He can then multiply $\frac{1}{3}$ by 30 to get a product of 10

$10\neq 15$

Since, 10 is not equal to 15, Harry's solution is not correct

<em><u>Correct solution:</u></em>

$\frac{1}{3}t = 15\\\\t = 15 \times 3\\\\t = 45$

Thus correct solution is 45

A chemical company makes two brands of antifreeze. The first brand is 20% pure antifreeze, and the second brand is 45% pure anti

kykrilka [37]

Answer:

First brand = 18 gallons

Second brand = 12 gallons

Step-by-step explanation:

Let the first brand brand be A and the second brand be B.

Thus, since he wants to obtain 30 gallons of a mixture that contains 30% pure antifreeze, then we have;

A + B = 30 - - - (eq 1)

Also; The first brand is 20% pure antifreeze, and the second brand is 45% pure antifreeze. Thus;

0.2A + 0.45B = (0.3 × 30)

0.2A + 0.45B = 9 - - - (eq 2)

From eq 1, we have; A = 30 - B

Put 30 - B for A in eq 2;

0.2(30 - B) + 0.45B = 9

6 - 0.2B + 0.45B = 9

0.25B = 9 - 6

0.25B = 3

B = 3/0.25

B = 12

Thus, A = 30 - 12 = 18 gallons
