#3-60 Simplify the following expressions.
Answer:
The solution is:
a. -18
b. -18
c. 24
d. 0
e. -4
4. 4
Step-by-step explanation:
Before we get into the solution, we remember the formula first, namely:
Addition
• (-) + (-) = (-)
• (+) + (+) = (+)
Subtraction
• (+) - (+) = can (-) and (+)
• (+) - (-) = (+)
Multiplication
• (-) x (-) = (+)
• (+) x (-) = (-)
Division
• (-) : (-) = (+)
• (+) : (-) = (-)
Solution:
a. 6(-3) = -18 ((+) × (-) = (-))
b. -6(3) = -18 ((-) × (+) = (-))
c. (-8)(-3) = 24 ((-) × (-) = (+))
d. -8(0) = 0 (whatever the number, if multiplied by 0 the result is still 0)
e. -20÷5 = -4 ((-) ÷ (+) = (-))
f. -36÷(-9) = 4 ((-) ÷ (-) = (+))

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.
If Salesman A has exactly
sales, he will reach his maximum weekly commission.

Answer:
47.06 + d = 150
Step-by-step explanation:
So she's planning to save 150 in total. She already saved 12.64. Her grandmother gave her three times as much as that (12.64 * 3=37.92). so an equation would be 12.64 + d + 37.92 - 3.50 = 150
(where d represents the amt. of money left she needs to earn.) If we add up 12.64 and 37.92, we get 50.56 - 3.50 + d = 150.
50.56 - 3.50 = 47.06, so now the equation is 47.06 + d = 150
Subtract: 150 - 47.06 = 102.94, so d = 102.94
Please help, I can't think today.

3. What is the value of x?
x = 41
x = 43
x = 47
x = 135
Answer:
x = 135
