Question

1) (x-25,46):7=8,99 2) 35,571y+64,429y=0,006

Answer 1

1) (x-25,46):7=8,99
Х-25,46=8,99*7
Х-25,46=62,93
Х=62,93+25,46
Х=88,39

2) 35,571y+64,429y=0,006
100у=0,006
У=0,006:100
У=0,00006

Answer 2

I assume that both expressions are equations and you want to solve for the variable in each case.

1. (x-25)/46 = 7/8.99

To solve for x, we can start by cross-multiplying:

8.99(x-25) = 46(7)

Expanding the brackets and simplifying, we get:

8.99x - 224.75 = 322

Adding 224.75 to both sides, we get:

8.99x = 546.75

Dividing both sides by 8.99, we get:

x ≈ 60.76

So the solution to the equation is x ≈ 60.76.

2. 35.571y + 64.429y = 0.006

To solve for y, we can combine the two terms on the left-hand side of the equation:

100y = 0.006

Dividing both sides by 100, we get:

y = 0.00006

So the solution to the equation is y = 0.00006.
