Let x be the large number, and y be the smaller one: x=3+2y, 2x-5y=0 (from the question) --> substitute the first equation in the second --> 2(3+2y)-5y=0 --> 6+4y-5y=0 -->6-y=0 --> y=6, substitute y=6 in the first equation --> x=3+2(6) --> x=15. therefore the two numbers are 6,15

A single tree produces about 2.6 x 10^2 lb of oxygen each year.The Amazon rainforest has about 3.9 x 10^11 trees.About how many
inna [77]
So to multiply standard form we multiply the 2 numbers and the 2 indices separately.

2.6*3.9=10.14
x^{2} *  x^{11} = x^{13}

So we've got 10.14*10^{13}
However Standard form must be 1 \leq x \leq 10 therefore we need to divide that by 10 but to get the same number we add one onto the power of 10.

So the answer is:

1.014*10^{14} lbs of oxygen are produced in the rainforest each year.

In a basketball game, a regular basket is worth 2 points and a long distance basket is worth 3 points. There were 54 baskets in
Alla [95]

Answer:

The system of equations for the given situation is:

x+y=54

2x+3y=118

Step-by-step explanation:

Given:

Regular basket is worth = 2 points

Long distance basket  is worth =3 points

Total baskets in a game = 54

Total points in total = 118

x\rightarrow represents the number of regular baskets

y\rightarrow represents the number of long distance baskets.

Expression for total baskets can be given by ⇒ x+y

Thus first equation representing total baskets in a game is given by:

x+y=54

Since a regular basket is worth 2 points

So x regular baskets would be worth =2x points

Since a long distance basket is worth 3 points

So y long distance baskets would be worth =3y points

Expression for total points in a game can be given by ⇒ 2x+3y

Thus second equation representing total points in a game is given by:

2x+3y=118

∴ The system of equations for the given situation is:

x+y=54

2x+3y=118
