Answer:

See below, please

Step-by-step explanation:

(2x + 9) + (4x - 3) = 90

6x + 6 = 90

6x = 90 - 6 = 84

Hence

x = 14

Answer:

Larger rocket: 36 kiloliters

smaller rocket: 24 kiloliters

Step-by-step explanation:

Lets assign the letters: "L" to the number of kiloliters the "Larger" rocket gets, and "S" to the number of kiloliters that the "Smaller" rocket gets.

We can create two equations from the words given in the problem:

First equation: <em>A total of 60 kiloliters is to be used for "L" plus "S"</em>:

which gives us: L+S=60

Next equation comes from the words: "<em>The smaller rocket receives 12 kiloliters less than the larger rocket</em>"

which gives us: S=L-12

Now we can use this last equation to replace for the "S" unknown in the first equation (and thus reducing the problem to one equation with one unknown (L), that one can easily solve):

L+S=60\\L+(L-12)=60\\2L-12=60\\2L=60+12\\2L=72\\L=\frac{72}{2}\\ L=36

Therefore the amount of fuel that the larger rocket gets is 36 kiloliters.

And using the equation  "S = L - 12" we get: S=36-12=24

Which tells us that the smaller rocket gets 24 kiloliters of fuel.

The length of the observable universe is.
alekssr [168]

Answer:

Kindly check explanation

Step-by-step explanation:

Organizations like NASA who explore space and planets often have to deal with measurement of very long distances such as the one stated above. The Major challenge with the distance written in the format expressed above is the difficulty to read, state or use in mathematical calculations as it is too explicit. A more effective method is to express this distance in standard format and more suitable long distant units such as miles.

For instance;

880,000,000,000,000,000,000,000 kilometers could be expressed as in standard form as ;

8.8 * 10^23 km
