Answer: Evaluate 2x2−3x+8 when x=−4 .
Substitute −4 for x. 2(−4)2−3(−4)+8
Simplify exponents. 2(16)−3(−4)+8
Multiply. 32−(−12)+8
Subtract. 44+8
Add. 52
Now we can evaluate expressions that include multiplication and division with integers. Remember that to evaluate an expression, substitute the numbers in place of the variables, and then simplify.
A negative number is always less than a positive number, so the only positive number, 5/3, is the greatest number of the three. -5/6 is less than -1/6, so the answer is:
-5/6, -1/6, 5/3
Answer:
5 11/12 cups of melon
Step-by-step explanation:
The cups of melon he puts in the fruit salad is:
Number of cups of orange melon + Number of cups of green melon
= 3 1/4 cups + 2 2/3 cups
3 + 2 + (1/4 + 2/3)
The Least common denominator is 12
5 + (3 × 1 +4 × 2/12)
5 + (3 +8/12)
5 11/12 cups
Therefore, Jason put in 5 11/12 cups of melon in the fruit salad.
