Answer:

x = 3

y = -5

Step-by-step explanation:

Since you have the value of y already, just plug it into the equation, like so:

6x + 8y = -22

6x + 8(-5) = -22

6x - 40 = -22

<em><u>Add 40 to both sides:</u></em>

6x - 40 = -22

    + 40  + 40

___________

6x = 18

<em><u>Finally, divide both sides by 6:</u></em>

6x = 18

x = 3

So now you have, x = 3 and y = -5.

The mass of Earth is 5.97 &gt;&lt; 1024 kilograms. The mass of the Moon is 7.34 x 1022 kilograms. What is the combined mass of E
LuckyWell [14K]

Answer:

7.34x10^22 kg can also be written as 0.0734 * 10^24 kg

Since both numbers are * 10^24, you can just add 5.97 + 0.0734 = 6.043. Then you have to add the * 10^24 giving you 6.043 * 10^24 kg

The ratio of Earth / moon is 5.97x10^24 / 7.34x10^22 = 81. The mass of the Earth is 81 times the mass of the moon.

Step-by-step explanation: give me brainliest please :)

Conversion. Write a reduced fraction notation for 0.56.
____ [38]

Answer:

Reduced fraction: 14/25

Step-by-step explanation:

To write 0.56 in terms of fractions we need to multiply and divide the number by 100:

(0.56 * 100)/100 = 56/100. Then we simplify the fraction by dividing the numerator and denominator by the common factor 2 as many times as possible:

56/100 = 28/50 = 14/25

The fraction 14/25 cannot be more simplified
