Evaluate the following.
÷45−9 =
×−9−5 =
÷45−9 = -9/45 - 9 = -18/2 - 9 = -9 - 9 = -18
×-9-5 = -9 * -5 - 5 = 45 - 5 = 40
To evaluate the given expressions, let's follow the order of operations.
1. ÷45−9:
Divide 45 by the result of subtracting 9 from it.
First, subtract 9 from 45:
45 - 9 = 36
Then, divide 36 by the result:
36 ÷ 36 = 1
Therefore, ÷45−9 = 1.
2. ×−9−5:
Multiply -9 by the result of subtracting 5 from it.
First, subtract 5 from -9:
-9 - 5 = -14
Then, multiply -9 by the result:
-9 × -14 = 126
Therefore, ×−9−5 = 126.
To evaluate the given expressions, we need to perform the mathematical operations specified. Let's start with the first expression:
÷45−9
First, let's clarify the division symbol "÷." It is equivalent to the division sign "/".
So, ÷45 means dividing a number by 45.
To evaluate ÷45−9, we need a number to divide by 45. For example, let's say we have the number 90.
Now we can perform the calculations step by step:
Step 1: Divide the number by 45: 90 ÷ 45 = 2
Step 2: Subtract 9 from the result: 2 - 9 = -7
Therefore, ÷45−9 equals -7.
Now let's move on to the second expression:
×−9−5
In this expression, × represents multiplication.
To evaluate ×−9−5, we need numbers to multiply.
Let's say we have two numbers, 4 and 3.
Now we can perform the calculations step by step:
Step 1: Multiply the first number by -9: 4 × -9 = -36
Step 2: Subtract 5 from the result: -36 - 5 = -41
Therefore, ×−9−5 equals -41.
