Answer:
-20x+128
Step-by-step explanation:
–8(x – 4) - (12x – 8)
distribute: -8x+32-12x+96
combine like terms
-20x+128
Step-by-step explanation:
4x+5y=4 (equation 1)
2x-y=9 (equation2)
solving equation 1 and 2 and multiplying equation 2 by 2
4x+5y=4
4x-2y=18
- + -
________
7y= -14
y= -2
putting the value of y in equation 2
2x-y=9
2x+2=9
2x=7
x=3.5
Answer:
-9
Step-by-step explanation:
-9+2-2=-9
The answer is 3/2 or 1.5
you substitute the variables with the numbers given and do the operations in the parenthesis first. then, subtract 5-2 and with that answer, you multiply it by your answer from the parenthesis
Your final answer will be 3/2
Answer:
The directed number suggested is +3.
Step-by-step explanation:
A directed number is one that has either a positive or negative sign, so that it could be easily located on the number line. Thus, the sign shows the direction of the number. Examples are: -2, -1, +5, +6 etc.
From the given question, let the initial weight be represented by W, then:
I gained 3 pounds implies at that; 3 pounds was added to my initial weight. Thus, my present weight is my initial weight + 3 pounds.
i.e I gained 3 pounds ⇒ W + 3
So that the directed number suggested by the statement is +3.
