Question

88,5148 – (172,44+168,59):67. а) 3,4 – 9х=1,6; б) 8,1:х – 0,7=2,3 а) 6,72,1; в) 3,419,73; б) 12,5:2,5; г) 5,45654:0,109 СРОЧНо!!!!!!!

Answer 1

172,44+168,59=341,03
88.5*148=13098
13098-341,03=12756,97
12756,97:67=190,4
ответ 190.4

Answer 2

88,5148 – (172,44+168,59):67
172.44+168,59=341.03
341.03:67=5.09
88,5148-5.09=83.4248

а) 3,4 – 9х=1,6;
-9х=1.6-3.4
-9х=-1.8
х=-1.8:(-9)
х=0.2

 б) 8,1:х – 0,7=2,3
8.1:х=2.3+0.7
8.1:х=3
3х=8.1
х=8.1:3
х=2.7

б) 12,5:2,5; = 5
г) 5,45654:0,109 =50.06

Answer 3

А) Let's solve the expression step by step:

88,5148 - (172,44 + 168,59):67

First, let's simplify the expression within the parentheses:

88,5148 - (172,44 + 168,59):67 = 88,5148 - 341,03:67

Next, let's divide 341.03 by 67:

= 88,5148 - 5.08955223880597

Finally, subtract the result from 88.5148:

= 83.42524776119403

Therefore, the value of the expression is approximately 83.4252.

Б) Let's solve the equation:

3,4 - 9x = 1,6

To isolate the variable x, we need to move the constant term to the other side of the equation:

3,4 - 1,6 = 9x

1,8 = 9x

Now, divide both sides by 9:

1,8/9 = x

x = 0,2

Therefore, the solution to the equation is x = 0.2.

В) The given expression is not clear. Please provide additional information or clarify the question.

Б) Let's solve the equation:

8,1/x - 0,7 = 2,3

First, let's isolate the term with x:

8,1/x = 2,3 + 0,7 8,1/x = 3

Next, let's multiply both sides by x to eliminate the fraction:

8,1 = 3x

Now, divide both sides by 3:

8,1/3 = x

x = 2.7

Therefore, the solution to the equation is x = 2.7.

Г) Let's solve the given expression:

5,45654/0,109

Divide 5.45654 by 0.109:

5,45654/0,109 ≈ 50

Therefore, the value of the expression is approximately 50.
