Hi there! Hopefully this helps!

<h2 /><h2>Answer: 235.</h2><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2><h2 />

First we need to <em>substitute the value of the variable</em> into the expression:

10a - 5b = 10(25) - 5(3).

Now we Multiply 10 and 25 to get <u>250</u>.

250 − 5 × 3 = 235

Multiply 5 and 3 to get <u>15</u>.

<u>250</u> − <u>15</u> = 235

<h2>Subtract 15 from 250 to get, you guessed it, 235!</h2>

Hernando ate StartFraction 2 Over 8 EndFraction of a pizza for a dinner. He gave his 6 friends the rest of the pizza and told th

ozzi

Answer:

Yes, they are correct. Hernando divided 6 by 6.

Step-by-step explanation:

Given that:

Hernando ate 2/8 of a pizza for dinner.

Let the pizza be x. Then:

Hernando ate $\dfrac{2}{8} \ \ o f \ \ x$

Then he gave the rest of the pizza to his friends

Hernando now carried out the following calculations to support his activities;

$\dfrac{6}{8} \div 6= \dfrac{6 \div 6}{8}= \dfrac{1}{8}$

$\dfrac{6}{8} \times \dfrac{1}{6}= \dfrac{6 \div 6}{8}= \dfrac{1}{8}$

From the above calculation; we will see that Hernando divided 6 by 6 in both cases to get $\dfrac{1}{8}$ .

Thus, the correct answer is:

Yes, they are correct. Hernando divided 6 by 6.
