For this case we must simplify the following expression:
We solve the parenthesis:
We apply distributive property to the terms within parentheses:
We add similar terms:
Answer:
Answer: 17.832 kg
Solution: (4458 grams)*(4 books)*
= 17.832 kg
In order to solve this problem, we transform the statements into
algebraic expressions. First, we assign the variables.
Let:
x = Gina’s number
y = Sara’s number
For the first equation, we show that Gina’s number is greater
than Sara’s number by 2. For the second equation, we show that the sum of both
numbers is 68.
<span>(1)
</span>x – y = 2
<span>(2)
</span>x + y = 68
<span>We
add the two expressions, which result in the expression: 2x = 70. Then we
divide 70 by 2 to get the value of x. We then have x = 35. Using the second
equation, we solve for y = 68-35. This gives y = 33. To summarize, Gina’s
number is 35 while Sara’s number is 33.</span>
The answer is 8/32 because 8 x 4 = 32
