Question

10002-3105÷a=9933 (A+736)×24=21888 75×a+8569=17869

Answer 1

10002-3105÷a=9933
10002-9933=69
3105÷69=45
45×69=3105
a=45
Ответ:45=а

(А+736)×24=21888
21888÷24=912
912-736=176
736+176=912
912×24=21888
А=176
Ответ:А=176

75×a+8569=18769
18769-8569=10200
10200÷75=136
136×75=10200
10200+8569=18769
Ответ 75×236+8569=18769

Answer 2

To solve these equations, we need to find the value of 'a.' Let's take them one by one:

1. 10002 - 3105 ÷ a = 9933

To isolate 'a,' we need to first get rid of the constant term (10002 - 3105) by subtracting it from both sides:

10002 - 3105 - 9933 = -3105 - 9933 6864 = -13038 ÷ a

Now, to solve for 'a,' we divide both sides by 6864:

a = -13038 ÷ 6864 a ≈ -1.9

2. (A + 736) × 24 = 21888

Let's simplify the equation step by step:

(A + 736) × 24 = 21888 Divide both sides by 24 to isolate (A + 736):

A + 736 = 21888 ÷ 24 A + 736 = 912

Now, subtract 736 from both sides to solve for 'A':

A = 912 - 736 A = 176

3. 75 × a + 8569 = 17869

Subtract 8569 from both sides to isolate 75a:

75a = 17869 - 8569 75a = 9300

Now, divide both sides by 75 to solve for 'a':

a = 9300 ÷ 75 a = 124

So, the solutions to the equations are:

1. a ≈ -1.9
2. A = 176
3. a = 124
