39. From her campsite, Ava estimated that she could see
2,500 stars without a
telescope. She read once that
a certain galaxy had 5 x 1011
stars. How many times more
stars does the galaxy contain
than what Ava estimates she
can see?
Scientific:
Standard:

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

answer: 1+1

step-by-step explanation: 1+1 is at least 2
