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

LiRa [457]

Answer: 8\sqrt{5}

Step-by-step explanation:

By the geometric mean theorem,

\frac{y}{16}=\frac{4}{y}\\\\y^{2}=64\\\\y=8

So, by the Pythagorean theorem,

8^2 + 16^2 = x^2\\\\320=x^2\\\\x=\boxed{8\sqrt{5}}

Darina [25.2K]

ANSWER:

<u>On solving equation by quadratic formula method, we get</u>

D = b² – 4ac

  • (–5)² – 4 × 1 × 3
  • 25 – 12
  • 13

D > 0, so it has real roots.

Now, x = – b ± √D/2a

  • – 5 ± √13/2

So, <u>Correct choice</u> - [A] & [C].
