4(-3) + 3(-5) + 7
-12+-15+7=-20
Answer:
D
Step-by-step explanation:
After you get the answer then you should feel in the d with the number. Example:
-20D=40
Divide both sides by -20
D=-2
So know you should fill in d
-20(-2)=40
40=40
True
For this case we have the following expression:
We must evaluate the expression when:
Substituting the values we have:
Equal signs are added and the same signs are placed.
Different signs are subtracted and the sign of the major is placed:
Finally we have to:
Answer:
False
The segments below could not form a triangle.
In this case, the Triangle Inequality Theorem is used. Basically, just add up the pairs:
9 and 7
9 and 16
7 and 16
Make sure when you add them up, the sum of the two sides is greater than the other side. Unfortunately, this is not true because 9 + 7 = 16. In order for this to have been true, the two sides would have had to equal a number greater than 16, not equal to.
Answer:
x = 10,000
Step-by-step explanation:
commision earned = $4500. - $4200
commision = 300
therefore:
commision = 3% of the amount of the sales
300 = 3% of x( the price isn't known)
300 = 3/100 * x
300 = 3x /100
multiplying both sides by 100
300 x 100 = 3x/100 x 100
30000 = 3x
Divide through by 3
x = 10,000.
the amount of the sales = 10,000
______________
To check
commision = 3% of 10,000
commision = 300
