Question

If 2/5 of 3x = 120, what is 1/5
x?​

Answer 1

Answer:

1/5 x=20

Step-by-step explanation:

2/5 of 3x=120

=> 3x=120×5/2=60×5=300

=> x=300/3=100

1/5*x=1/5*100=20

Answer 2

Concept

Equations are logical assertions in mathematics that have two algebraic expressions on either side of an equals (=) sign. The expressions on the left and right are shown to be equivalent to one another. A mathematical equation resembles a balance scale with identical weights on either side. An equation remains true whether the same integer is added to or subtracted from both sides.

Given

2/5 of 3x =120

Find

what is 1/5x = ?

Solution

from the given data, 1/5 × x

based on the given conditions 2/5 × 3x= 120

from the given equation, rewrite the expression 1/6 × 2(3x)/5

2(3x)/5 = 120

substitute = 1/6 ×20

= 20

hence we get the answer as 20.
