Answer:

Hey there! First you start with parenthesis! So distribute the 2 to 3x. There you get 6x. Now distribute to the 3. You get 6. Now you move the 2x over to the right side. Getting 30=4x+6.. Now move the 6 over to the 30. You get 24=4x..Now you divide, getting the answer 6! Hope this helps...

Answer is 6

Answer:

Part A: (0.25+0.30+0.75) - 0.20

Part B:

Step-by-step explanation:

The jar contains 0.25 of apple juice and 0.30 liter of grape juice. Then, another 0.75 litter is added. Melissa drank 0.20 of that, making the value lower (Hint: subtraction).

So we have to add 0.25, 0.30, and 0.75. Subtract it by 0.20. My equation would look like:

(0.25+0.30+0.75) - 0.20

The simplified equation will be:

1.3 - 0.20

= 1.1

I used the associative property to simplify the parenthesed part of the equation, and subtracted it by 1.1. Even though it has been simplified, the result has no changed and it is still the same value as it would have been in the previous equation.

Best of luck, and have a blessed day! For any question or comments, please say so!

faust18 [17]
It should be 5√3

Because 25 x 3 = 75

√25=5 so u bring that out and keep the 3 in because it’s a prime number

6 times the difference of a number and 4 equals 7
Nonamiya [84]
6( x - 4) = 7
6 x - 24 = 7
6 x = 7 + 24
6 x = 31
x = 31/6 

6 ( 31/6 - 4) = 7 
186/6 - 24 = 7
186/6 = 144/6 = 7

42/6 = 7 
7 = 7
