Question

(350 : b + 10) * 7 = 560

Answer 1

(350÷b+10)×7=560
350÷b+10=80
350÷b=70
b=5

Answer 2

$( \frac{350}{b} + 10) \times 7 = 560$
$\frac{350 + 10b}{b} \times 7 = 560$
$\frac{5(70 + 2b)}{5} \times 7 = 560$
$\frac{35(70 + 2b)}{b} = 560$
$2450 + 70b = 560b$
$490b = 2450$
$b = \frac{2450}{490}$
$b = 5$
Ответ: 5.

Answer 3

To solve for the value of "b" in the equation:

(350 : b + 10) * 7 = 560

We need to isolate "b" on one side of the equation. We can start by simplifying the expression inside the parentheses by performing the division:

(350 : b + 10) = 80

Next, we can multiply both sides of the equation by (b + 10) to isolate "b":

350 = 80(b + 10)

Expanding the right side of the equation:

350 = 80b + 800

Subtracting 800 from both sides:

-450 = 80b

Finally, dividing both sides by 80:

b = -5.625

Therefore, the value of "b" that satisfies the equation is -5.625.
