Question

На турбазе летом проживало 200челавек в палатках и 180человек в доме. К осени число людей в палатках уменьшилось в 8раз, а в доме в 2раза. Сколько туристов было на базе осенью? Схема ношение. 4045:5+451•75-(729-642)=? 320:(52-x)=8

Answer 1

1) 200/8=25 человек в палатках осенью
2) 180/2=90 человек в доме осенью
3) 25+90=115 человек было на базе осенью

320:(52-х)=8
52-х=320:8
52-х=40
х=52-40
х=12

4045:5+451*75-(729-642)=809+33825-87=34547
4045:5=809
451*75=33825
729-642=87

Answer 2

To solve the given problems, let's break them down step by step.

Problem 1: Number of tourists in tents and in the house during the summer

According to the information given, there were 200 people staying in tents and 180 people staying in the house during the summer.

Problem 2: Reduction in the number of tourists in tents and in the house by autumn

The number of people staying in tents decreased by 8 times, and the number of people staying in the house decreased by 2 times.

To find the number of tourists in tents and in the house during autumn, we need to multiply the initial numbers by the reduction factors.

Number of tourists in tents during autumn = 200 (initial number) * 8 (reduction factor) = 1600.

Number of tourists in the house during autumn = 180 (initial number) * 2 (reduction factor) = 360.

Therefore, there were 1600 tourists in tents and 360 tourists in the house during autumn.

Problem 3: Solving the equation 4045:5 + 451•75 - (729-642)

Let's solve the equation step by step:

4045:5 + 451•75 - (729-642)

First, let's perform the division: 4045 divided by 5 equals 809.

809 + 451•75 - (729-642)

Next, let's perform the subtraction inside the parentheses: 729 - 642 equals 87.

809 + 451•75 - 87

Now, let's perform the multiplication: 451 multiplied by 75 equals 33,825.

809 + 33,825 - 87

Finally, let's perform the addition and subtraction:

809 + 33,825 - 87 = 34,547.

Therefore, the result of the equation 4045:5 + 451•75 - (729-642) is 34,547.

Problem 4: Solving the equation 320:(52-x) = 8

Let's solve the equation step by step:

320:(52-x) = 8

First, let's simplify the equation by multiplying both sides by (52-x):

320 = 8(52-x)

Next, let's distribute 8 to both terms inside the parentheses:

320 = 416 - 8x

Now, let's isolate the variable by subtracting 416 from both sides:

320 - 416 = -8x

-96 = -8x

Finally, let's solve for x by dividing both sides by -8:

-96/-8 = x

12 = x

Therefore, the value of x in the equation 320:(52-x) = 8 is 12.
