Set up the multiplication vertically. Remember to 416 \u00d7 70 = Start by writing four and two fifths as an improper fraction: 4 2\/5 \u2212 3\/5 = The denominator of each fraction is 5. Since the 4\/5 \u2212 1\/5 = The number 4 can be written as 4\/1, which has 4 \u2212 1\/3 = Use long division: 5 goes into 661 132 times, with a remainder of 1.Use long division: 5 goes into 661 132 times, with a remainder of 1.<\/a><\/p>\n\n\n\n 5 \/661 = The three fractions have a common denominator 1\/5 + 1\/5 + 2\/5 = Write each mixed number as an improper fraction. 5 1\/2 + 3 9\/10 = Write the subtraction vertically. In the ones column, 8 can’t be subtracted from 4, so we borrow a 10 from the tens column. $14.50 \u2212 $8.00 = Line up the decimals at the decimal point. 22.9 + 0.5 = To multiply decimals, multiply as you would if they were whole numbers. Multiply without using a calculator. The total earnings will be base salary plus commission. The base salary is $10,000. The commission is 15% of $90,000, or $13,500. The total base salary plus commission is $23,500.<\/a><\/p>\n\n\n\n This table is used to calculate annual commissions and salaries for car salespeople.

Draw the line through (4, 5) with a slope that goes down A line contains the point (4, 5) and has a slope of \u22122. The formula for the area of a trapezoid is: The area of a trapezoid is 864 cm^2. It has a height of 24 cm, and the length Start by drawing a diagram, and label the diagonal x. Note that each side length of the playground is 12\/04 = 30 yd. Use the Pythagorean Theorem to find x. A square playground has a perimeter of 120 yards. What is the length of a diagonal of the playground? d dollars worth of merchandise was sold on Tuesday. On Tuesday, d dollars worth of merchandise was sold. On Wednesday, the amount Multiply, and then combine like terms: Simplify the expression: The line shown on the graph is y = 3x + 10y = 3x + 10 . Use the point-slope form of a line, What is the equation of the line? First, get like terms on the same side of the equal sign. Then isolate the variable.

Let m represent Monday’s eggs, and write an expression for Tuesday’s production level. Solve as you would an equation, except when you divide by \u22122, you need to flip the inequality symbol. Solve for t. To solve this question, you must solve the equation for x. The first step is to simplify by distributing the \u22126 into the parentheses. The next step is to combine like terms. Finally, isolate x. If 10x \u2212 6 + 18x \u2212 6(2x\u22124) = 2, what is the value of x? First multiply by 2 to rid the equation of the fraction.

Note that each side length of the playground is A square playground has a perimeter of 120 yards. As the amount of sunlight increases from 4 to 5 to 6 hours, the plants grow more per week. The plants that get more sunlight are growing more quickly. According to the information in the graph, longer exposure to sunlight tends to result in more rapid growth.<\/a><\/p>\n\n\n\n The graph shows the amount of growth in plants exposed to different amounts of sunlight. What is a reasonable conclusion, based on the data in the graph? Because the graph is strictly increasing, you can say that the price of bread increases with the cost of oil, so there is a relationship. However, the rate of increase (the slope) varies, so it is not a linear relationship, and therefore not proportional.<\/a><\/p>\n\n\n\n The graph plots the relationship between the price of oil and the price of bread in the United States. What can be said about this relationship? The answer is 8\u221a2. Factor the radicands in \u221a50 + \u221a18. You get \u221a25 \u22c5 2 +\u221a9 \u22c5 2 . Pulling out the perfect squares gives 5\u221a2 + 3\u221a2. Because they are like radicals, you can add these.<\/a><\/p>\n\n\n\n Find \u221a50 +\u221a 18. Write your answer in simplest terms.

The median, or middle, cost of the three original prints is $35. When a fourth price is added to the list of prices, the median is the number halfway between the two middle prices. The price halfway between $35 and $45 is $40, so $40 is the new median price. The median price has changed from $35 to $40, a difference of $5.<\/p>\n\n\n\n An art gallery is selling three poster prints of paintings, costing $26, $35, and $50.
