Evaluate ab - cd =<br> a = 5, b = 3, c = 4, d = 2
Westkost [7]

Answer:

7

Step-by-step explanation:

ab - cd = ?

Put the numbers into the correct variables of the equation.

(5)(3) - (4)(2) = ?

Now multiply 5 and 3 with each other. This leaves you with:

15 - (4)(2) = ?

Now, multiply 4 and 2 with each other. This leaves you with:

15 - 8 = ?

Now, you are able to solve the equation.

15 - 8 = 7

Suzie went to a candy shop. The candy shop has a sign that shows the cost of the candies at the shop. The sign is below:
aleksklad [387]

Answer:

$8.50

Step-by-step explanation:

Multiply the cost by the amount of candy she bought, your equation will look like this:

2(0.75) + 3(1) + 5(1.40)

Multiplying everything makes the equation into:

1.5 + 3 + 7

Adding everything makes the total cost 11.50.

Subtract 11.50 from 20, and the answer is 8.50
