Carl bought 19 apples of 2 different varieties to make a pie. The total cost of the apples was $5.10. Granny Smith apples cost $0.25 each and Gala apples cost $0.30 each. How many of each type of apple did Carl buy?

Answers

Answer 1

Answer:

Step-by-step explanation:

Split 19 into 2, since Carl bought two types of apples.

19/2 = 9.5

0.25 x 9 = 2.25

0.3 x 9 = 2.7

2.25 + 2.7 = 4.95

5.10 - 4.95 = 0.15

0.3 x 8 = 2.4

2.25 + 2.4 = 4.65

5.1 - 4.65 = 0.45

Write 28 x 32 in associative property

Answers

Answer:

32 * 28

Step-by-step explanation:

Just flip the positions of the two and you have your answer

the associative property states that (in this case) changing the order of the numbers in the equation does not change the product. for example, "a" times "b" is equal to "b" times "a". this means 28 x 32 is equal to 32 x 28. so, 28 x 32 using the associative property is 32 x 28.

The account balance of each of three children at the end of a month is shown below: John has −$2.75

Andrew has as much savings in his account as the amount John owes the bank.
Part A: On a blank paper, draw a number line from −4 to +4. Plot points on the number line to show the account balances of the three children. Label the points using the name of each child. Describe in detail how you created and labeled this number line, and what it looks like in detail. (5 points)

Cheryl owes more money to the bank. |-3| = 3 and |-2.75| = 2.75. As you can see Cheryl's amount of money is greater when you find the absolute value of it, but since it was negative it means that she actually owes more money.

How would you solve this problem? (Worth 10 points, pls help!)

Answers

Answer:

(22,0)

Step-by-step explanation:

1. Select any two points given and find their slope (rise/run)

       (-38, 40) and (-23, 30)

      slope =   [tex]\frac{40-30}{-38-(-23)}[/tex] = - 2/3

2. Use the slope and one of the points to create an equation of the line in the format y = mx + b, where m = slope and b = y-intercept.

    y = mx + b ⇒ 40 = -2/3 (-38) + b

3. Solve for b

   40 = -2/3 (-38) + b

   40 = 76/3 + b

   40 - 76/3 = b

   b = 44/3

4. To find the x-intercept, set y = 0, and solve.

   y = -2/3 x + 44/3

   0 = -2/3 x + 44/3

   2/3 x = 44/3

   x = 22
