Which of the following choices is an equivalent expression for (12r + 2t) - (4r + 10t) Which of the following choices is an equivalent expression for (12r + 2t) - (4r + 10t)

A

8(r - t)

B

8(r + t)

C

8r + 7t

A

Step-by-step explanation:

you use the minus sign to open the second bracket

then you collect the like terms and factorize

then you put the one that occur on both side outside and bracket the rest

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
