Which equation shows the variable terms isolated on one side and the constant terms isolated on the other side for the equation
riadik2000 [5.3K]

Answer:

3x=-2+10+5  

x=13/3

Step-by-step explanation:

we have

3x-5=-2+10

Solve for x

That means ---->  Isolated the variable x

Adds the constant term 5 both sides

3x-5+5=-2+10+5

3x=-2+10+5 ----> variable terms isolated on one side and the constant terms isolated on the other side

Combine like terms

3x=13

Divide by 3 both sides

x=13/3

Answer:

5sqroot3

Step-by-step explanation:

see image.

An integer is just a whole positive or negative (positive in this case) number that's not a fraction or decimal or mixed number. In the answer that is the 5.

To simplify a radical, look for a factor that is a perfect square. Radicals and multiplying are very friendly to each other and you can separate the "radicand" (the inside number) into factors inside the radical also into separate radicals to simplify. See image

Convert kilogram into gram first.

1 kg = 1000g

2kg = 1000 \times 2 \\  = 2000

a:b = a/b

125:2000= 125/2000

If u divide u get

1/16

a:b = a/b

1/16= 1:16

Ratio is now found.
