Question

A) x = (459 - 147 – 62) - 50; 6) y = 30.568 - 416. 40; B) z = 270 400 : 52 : 26.помогииие​

Answer 1

Ответ:

a) x = (459 - 147 – 62) - 50;

х=200

6) y = 30.568 - 416. 40;

y=−412,832

B) z = 270 400 ÷ 52 ÷ 26.

z= 20,2662721893

Answer 2

A) Let's solve the equation for x: x = (459 - 147 – 62) - 50

To solve this equation, we need to perform the operations inside the parentheses first. Let's start with the subtraction inside the parentheses: x = (250 - 62) - 50

Next, we perform the subtraction inside the parentheses: x = 188 - 50

Finally, we subtract 50 from 188: x = 138

Therefore, the value of x is 138.

B) Now let's solve the equation for y: y = 30.568 - 416 + 40

To solve this equation, we need to perform the operations in the correct order. First, we perform the subtraction: y = -385.432 + 40

Next, we perform the addition: y = -345.432

Therefore, the value of y is -345.432.

C) Finally, let's solve the equation for z: z = 270 + 400 : 52 : 26

To solve this equation, we need to perform the division first. Let's start with the division: z = 270 + 400 / 52 : 26

Next, we perform the division: z = 270 + 7.692307692307692 : 26

Finally, we perform the division and addition: z = 270 + 0.29615384615384615

Therefore, the value of z is approximately 270.296.
