Holland added three decimals that made a sum of 2. One of the decimals was 0.34. What are two other decimals Holland could have

ddd [48]

From this question, you can conclude:
1. There are 3 decimal
2. Decimal1 + decimal2+ decimal3= 2
3. The first decimal is 0.34

If you insert the 3rd into 2nd equation, it will become:
0.34+ decimal2+ decimal3= 2
decimal2+ decimal3= 2-0.34
decimal2+ decimal3= 1.56

If there are no rules regarding the second and third decimal, then you can use this both
1.01 + 0.55
0.78 + 0.78

What is the solution to the system? x + y = 4 x+y=1

Lelechka [254]

<u>Given</u><u> </u><u>:</u>

x + y = 4
x + y = 1

<u>To</u><u> </u><u>Find</u><u> </u><u>:</u>

The value of x and y.

<u>Answer</u><u> </u><u>:</u>

x + y = 4 ....[Equation (i)]
x + y = 1......[Equation (ii)]

<u>Adding</u><u> </u><u>eqⁿ (ii) </u><u>and</u><u> eqⁿ (i) we get :</u>

→ x + y + x - y = 4 + 1

→ 2x = 5

→ x = 5/2

→ x = 2.5

<u>Now</u><u>,</u><u> </u><u>put</u><u> </u><u>the</u><u> </u><u>value </u><u>of</u><u> </u><u>x</u><u> </u><u>=</u><u> </u><u>5</u><u>/</u><u>2</u><u> </u><u>in</u><u> </u><u>eqⁿ</u><u> </u><u>(</u><u>i</u><u>)</u><u> </u><u>we</u><u> </u><u>get</u><u> </u><u>:</u>

→ x + y = 4

→ 5/2 + y = 4

→ y = 4 - 5/2

→ y = 1.5
