Answer 3

1. Вычисление выражений:

a) Вычислите: 795 * 829 + 3042 : 39 =

To calculate this expression, we can follow the order of operations (PEMDAS/BODMAS). First, we perform the division:

3042 ÷ 39 = 78

Next, we perform the multiplication:

795 * 829 = 658,755

Finally, we add the results together:

658,755 + 78 = 658,833

Therefore, 795 * 829 + 3042 : 39 = 658,833.

b) Вычислите: 94953 - 15038 : 73 * 407 =

Again, we follow the order of operations. First, we perform the division:

15038 ÷ 73 = 206

Next, we perform the multiplication:

206 * 407 = 83,842

Finally, we subtract the result from the initial number:

94953 - 83,842 = 86,111

Therefore, 94953 - 15038 : 73 * 407 = 86,111.

2. Упрощение выражения:

Упростите выражение: 150 * p * 670 * q.

To simplify this expression, we can multiply the numbers together:

150 * p * 670 * q = 100,050 * p * q = 100,050pq.

Therefore, the simplified expression is 100,050pq.

3. Решение уравнения:

Решите уравнение: x : 15 = 225 + 104y - 12 = 1132 + 29 * (145 - 6z).

To solve this equation, we need to simplify it step by step.

First, let's simplify the right side of the equation:

225 + 104y - 12 = 1132 + 29 * (145 - 6z) 213 + 104y = 1132 + 29 * (145 - 6z)

Next, let's simplify the expression inside the parentheses:

213 + 104y = 1132 + 29 * 139 213 + 104y = 1132 + 4,031 213 + 104y = 4,165

Now, let's isolate the variable y:

104y = 4,165 - 213 104y = 3,952

Divide both sides of the equation by 104:

y = 3,952 / 104 y ≈ 38

Therefore, the solution to the equation is y ≈ 38.

4. Решение задачи:

Решите задачу: 344 кг сахара расфасовали в пакеты по 2 кг, 3 кг и 5 кг. В двухкилограммовые поместилось 128 кг сахара, трехкилограммовых пакетов получилось в 2 раза меньше, чем двухкилограммовых. Сколько получилось пятикилограммовых пакетов?

Let's solve this problem step by step.

Let's assume the number of 2 kg packets is x. Since the weight of sugar in 2 kg packets is 128 kg, we can set up the equation:

2x = 128

Solving for x, we find:

x = 128 / 2 x = 64

So, there are 64 packets of 2 kg.

Since the number of 3 kg packets is 2 times less than the number of 2 kg packets, we can set up the equation:

3y = 64 / 2 3y = 32

Solving for y, we find:

y = 32 / 3 y ≈ 10.67

Since we can't have a fraction of a packet, we round y down to the nearest whole number. Therefore, there are 10 packets of 3 kg.

Now, let's find the number of 5 kg packets. We know that the total weight of sugar is 344 kg, and we have already accounted for 128 kg in 2 kg packets and 30 kg in 3 kg packets. So, the remaining weight is:

344 - 128 - (10 * 3) = 344 - 128 - 30 = 186 kg

Since each 5 kg packet contains 5 kg of sugar, we can find the number of 5 kg packets:

186 / 5 ≈ 37.2

Again, we round down to the nearest whole number. Therefore, there are 37 packets of 5 kg.

Therefore, the number of 5 kg packets is 37.
