If 20% of a number is 8, what is 25% of the number?

2 answers:

3 0

20%*x = 8

20% = 2/10

2/10*x = 8 |(*10/2)

2/10*10/2*x= 8 * 10/2 2/10*10/2 =>1
1*x = 80/2
x=40

25% from 40 is 10
25% = 1/4
1/4 * 40 = 40/4 = 10

Answer:

Set up an equation as 0.2x = 8, which means 20 percent of x equals 8. Solve the equation by dividing each side by 0.2. Dividing 0.2 from each side results in x = 40. Eight is 20 percent of 40.

Paha777 [63]

Answer:

A. 35

Step-by-step explanation:

a || b .....(given)

line c is their transversal.

-> x° + (3x + 40)° = 180° (Interior angles on the same side of transversal)

-> (3x + 40 + x)° = 180°

-> (4x + 40)° = 180°

-> 4x + 40 = 180

-> 4x = 180 - 40

-> 4x = 140

-> x = 140/4

-> x = 35
