X = 4

7(4)+14-3(4)=30

7(-11)+14-3(-11)=-30

So, 4 is the answer because when substituted for X, it gives you 30.

Answer:

A=4

Step-by-step explanation:

7x+14-3x=30

collect the like terms 7x-3x=4x than

it's gonna be 4x+14=30 and move constant to the right side and change its sign 4x=30-14 and subtract 30-14=16

4x=16 and divide both sides of the equation by 4

it's gonna be x=4

Jacob used 1/7 of a liter of water to fill 1/9 of the fish aquarium. How many liters of water are needed to fill the aquarium?
laila [671]
Jacob used 1/7 of a liter of water.
He needs to fill 1/9 of the fish aquarium.
Find how many liters would Jacob need to fill the aquarium
=> Let x = liters of water need to fill the aquarium
=> x/1 = 1/7 divided by 1/9
=> x = 1/7 x 9/1
=> x = 9/7, since this is an improper fraction, let’s convert it to mixed fraction
=> x  = 1 and 2/7
So, Jacob need 1 and 2/7 liter of water to fill the whole aquarium.

Sabric and Jessica disagree over an inequality statement. Sabric claims that -3.613 > -3.63. Jessica claims that -3.613 <
Yanka [14]
Sabric's claim is correct because in a number line -3.613 is closer to the zero than -3.63.
_______________________________________________________________
      -3.63                                       -3.613                                    0          1          2..

Also the place value can tell you which is greater:       3.613
Notice the 1 and the 3:                                                     3.63
The smaller number when using negatives is closer to the zero than the bigger one.
