The first step to solving this is to eliminate the opposites.
-5 × (-5) - ((3 - 4) × 2)
Calculate the difference from the expression in the parenthesis.
-5 × (-5) - (-1 × 2)
Multiply the numbers on the left side of the expression
25 - (-1 × 2)
Any expression multiplied by -1 equals the opposite,, which will change the expression to the following:
25 - (-2)
When there is a "-" sign in front of the parenthesis,, you must change the sign of each term in the parenthesis. This rule will make the expression look like the following:
25 + 2
Finally,, add the numbers together to get your final answer.
27
This means that the correct answer to your expression is 27.

Answer:
(- 2, 4 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) , then the midpoint is
( , )
Here (x₁, y₁ ) = A (4, 6 ) and (x₂, y₂ ) = B (- 8, 2 )
midpoint = ( , ) = ( , ) = (- 2, 4 )
Answer:
336
Step-by-step explanation:
7x48=
7(8)= 56
7(4)+5= 33
7(48) = 336
Answer:
3/2
Step-by-step explanation:
The ratio 6:4 can be rewritten as 6/4, which can be simplified to 3/2
6 and 4's greatest common factor is 2, so dividing both by two simplifies the fraction;.
Answer: $2.95
Step-by-step explanation:
Given: Probability of losing the $7 =
Probability of winning $14 =
Then, the expected value = (- $7) x ( Probability of losing the $7) + $14 x(Probability of winning $14)
=
=
=
∴ If a doctor pays $7 that the outcome is an odd number, the doctor's
expected value is $2.95.
