Question

X×0.01+5,04÷1,4=21,64 0,1×y-562÷10=132 7,19×10+z÷100=89,58

Answer 1

Ответ:

1) x=1804

2) y=1882

3) z=1768

Answer 2

To solve these equations, we can isolate the variables step by step. Here's how you can solve each equation:

1. X × 0.01 + 5.04 ÷ 1.4 = 21.64

First, let's simplify the equation:

0.01X + 5.04 ÷ 1.4 = 21.64

Now, subtract 5.04 ÷ 1.4 from both sides:

0.01X = 21.64 - (5.04 ÷ 1.4)

0.01X = 21.64 - 3.6

0.01X = 18.04

Now, divide both sides by 0.01 to solve for X:

X = 18.04 / 0.01 X = 1804

So, the value of X is 1804.

2. 0.1 × y - 562 ÷ 10 = 132

First, let's simplify the equation:

0.1y - 562 ÷ 10 = 132

Now, add 562 ÷ 10 to both sides:

0.1y = 132 + (562 ÷ 10)

0.1y = 132 + 56.2

0.1y = 188.2

Now, divide both sides by 0.1 to solve for y:

y = 188.2 / 0.1 y = 1882

So, the value of y is 1882.

3. 7.19 × 10 + z ÷ 100 = 89.58

First, let's simplify the equation:

71.9 + z ÷ 100 = 89.58

Now, subtract 71.9 from both sides:

z ÷ 100 = 89.58 - 71.9

z ÷ 100 = 17.68

Now, multiply both sides by 100 to solve for z:

z = 17.68 × 100 z = 1768

So, the value of z is 1768.
