So in these problems, we're dealing with absolute value. Absolute value is the real amount of the number, or it's real place value without a negative sign.
Part A: if the absolute value of X was 17, then X could equal -17 or 17.
Part B: |x+9|=15. We know that 6+9=15, so X could equal -6 or 6.
Part C: |x-10| ≤ 13. We know that 23-10 is 13. So 23 would be the greatest value of X. Then, for the smallest value of X, if we insert -3 in the equation to take the place of the variable, we get |-3-10|=13. So -3 would be the smallest value of the equation. X≤ 23 and X≥-3.
Answer:
$110, $44
Step-by-step explanation:
Let x = the total cost to Stefan
Jim buys for:
bicycle: $138
helmet: $16
total: $138 + $16 = $154
Jim's price of $154 is 140% of Stefan's cost, x.
154 = 140% × x
1.4x = 154
x = 110
Stefan spent $110.
Stefan's profit:
$154 - $110 = $44
Answer: $110, $44
9 inches, divide 108 by 12, because 12 inches makes a foot
Answer: 92,700
Step-by-step explanation:
9,270,000 / 100 = 92,700
Answer:
One big reason why a car’s total price won’t match the price on its window sticker relates to fees charged by a car dealership and the automaker. For example, although a car may cost $19,995 according to the window sticker, that figure might be the price before the addition of a destination charge, which is a pricy manufacturer’s fee that can add up to $1,000 to the price. A dealer may also charge a documentation fee to prepare the vehicle’s documents for sale, and this figure can sometimes cost as much as $500. There are mandatory government fees too, such as the cost to process the car’s title work or change the registration to your name.
Step-by-step explanation:
Dealer and manufacturer fees usually aren’t the biggest add-ons to a car’s purchase price. The priciest addition typically comes in the form of taxes, since most states levy a sales tax on the entire price of a new or used vehicle. Since sales taxes can range as high as 8-10 percent in some areas, this can easily add thousands of dollars to your vehicle’s purchase price. For example, a $20,000 car purchased in an area with a 7 percent sales tax will cost an extra $1,400 on top of the purchase price, while a $30,000 car bought in a place with a 9 percent sales tax will see a whopping $2,700 price boost before you can drive it home.
