HELPP!!! Isn't one of the answers supposed to be 3?????

Answers

Answer 1

Step-by-step explanation:

well, it is supposed to be -3.

but you are right. something is wrong or missing here.

5x + 3 = 4x

x + 3 = 0

x = -3

maybe a "+ 1" is missing on the right side ?

5x + 3 = 4x + 1

gives us

x = -2

Answer 2

Basically the equation is 5•2+3 which is 13 because you multiply 5 and 2 first then whatever answer you get plus 3

Answers

Answer: B, E, and F.

Step-by-step explanation: -$300 means negative 300 which is not a gain, it is a loss as negative numbers are losses. So A is wrong. +400 indeed is a gain as it is a positive and has an addition sign in front of it Using this knowledge we can see that besides B, only E and F are correct.

Answer:

a. The resulting product cannot be greater than-10. (False)

b. The resulting product must be greater than 0. (True)

c. The resulting product cannot be less than 10. (True)

Step-by-step explanation:

Explaining Statement (a):

The integer that is given is -10,

Let it will b multiplied with another negative integers let say (-1). Starting with the smallest one in order to clarify all statement.

So, if the resultant product is represented by x, So:

x = (-10)(-1)

Using the sign Multiplication rule which is {(-)*(-)} = +

x = 10

While looking at the result It is greater than -10 because 10 is greater than -10 (So, First Statement is False)\Similarly, the resulting product is greater than 0 because 10 is greater than 0 (So, 2nd statement is true)At the end, the minimum integer choose to multiply with the -10 will be -1. It neither be -0.5 because -0.5 is not an integer. Hence answer will never ever be less than 10. (Last statement is True)
