Tony worked 4 2/3 hours on his science project. Sonia worked 1 1/4 times as long on her science project as Tony did.For how many

kherson [118]

To find how many hours Sonia work on her science project,we can multiply the working hours of Tony by the times Sonia did:

$4 \frac{2}{3} \times 1 \frac{1}{4} \\ = \frac{14}{3} \times \frac{5}{4} \\ = \frac{70}{12} \\ = 5 \frac{10}{12} \\ = 5 \frac{5}{6}$
Therefore Sonia work on her science project for 5 5/6 hours.

Hope it helps!

Evaluate the given algebraic expressions replacing x with -2 and y with 1<br><br>3x^2

Anvisha [2.4K]

Answer:

Step-by-step explanation:

3x^2

because the information provided states that x = -2, that is what we are going to replace x with.

3(-2)^2

the next step is to evaluate the power because that is next in PEMDAS.

(-2)^2 = 4

that leaves us with:

3 * 4 = 12 ( the " * " represents the multiplication sign)

hope this helps!
