Точная форма: x = 13/10 Форма смешнанных чисел: 1 3/10

Answer 2

10x+1.5*(2.3-1.7)=13.9
10x+1 1/2*(2 3/10-1 7/10)=13 9/10
10x+69/20-51/20=13 9/10
10x+18/20=13 9/10
10x=13 9/10-18/20
10x=13 0/20
10x=13
x=13/10
x=1 3/10

Answer 3

To solve the equation 10x + 1.5 * (2.3 - 1.7) = 13.9, we can follow these steps:

Step 1: Simplify the expression on the right side:

2.3 - 1.7 = 0.6

1.5 * 0.6 = 0.9

So the equation becomes 10x + 0.9 = 13.9.

Step 2: Subtract 0.9 from both sides to isolate the term with x:

10x + 0.9 - 0.9 = 13.9 - 0.9

10x = 13.9 - 0.9

10x = 13

Step 3: Divide both sides of the equation by 10 to solve for x:

(10x)/10 = 13/10

x = 1.3

Therefore, the solution to the equation 10x + 1.5 * (2.3 - 1.7) = 13.9 is x = 1.3.
