Clouds form as water evaporates from the ocean. When the clouds get large enough, it rains, and if the temperature is cold enough, it may snow. The water found in Earth's atmosphere is 0.00095% of earth's total amount of water. How much water is in earth's atmosphere?

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

what statement? is there an image?

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
