Question

найдите число А, если отношение 5/18 числа А к 30% числа (А+14) равно 2/3.

Answer 1

А*(5/18) разделить на 0,3*(А+14) =2/3
А= 36

Answer 2

3*5А/18=2*0.3(A+14)

5A/6=0.6A+8.4

ДОМНОЖИМ НА 30:

25А=18А+252

25А-18А=252

7А=252

А=252:7

А=36

ОТВЕТ: 36

Answer 3

I can help you with your math problem.

To find the number A, we need to solve the equation:

$$\frac{5}{18}A = \frac{2}{3} \times 0.3 (A + 14)$$

First, we simplify the fractions and multiply both sides by 18:

$$5A = 12 (A + 14)$$

Then, we expand the brackets and move all the terms with A to the left side:

$$5A - 12A = 12 \times 14$$

Next, we combine the like terms and divide both sides by -7:

$$-7A = 168$$

$$A = -24$$

Therefore, the number A is -24.Ответь+подробно.+найдите+число+А,+если+отношение+5/18+числа+А+к+30%+числа+(А+14)+равно+2/3.
