Answer:
Step-by-step explanation:
Jonah sister is 10 years old. Jonah is 8 years younger than twice hos sister age
j = 2s - 8
this is the equation.
You can solve it by substituting in 10 for s, because sister is 10 years old.
F^-1(x) = sqrt 2(-5+x)/2, - sqrt 2(-5+x)/2
<u>Part A
</u><u />To estimate this, we should first look at our fractions and see if they can be combined to form a whole number. In this case,

and

equal approximately 1. We can add this "1" to the other to full gallons to estimate that the painter needs about
3 gallons.
<u>Part B
</u><u /><u />To find the exact amount, we should first change the mixed numbers to improper fractions. We do this by multiplying the denominator by the whole number, adding the numerator, and placing that value over the denominator.

Now, we need to find the least common denominator. This is the lowest value that both denominators will divide evenly into. In this case, that number is 15.
Next, we should multiply both fractions so that the denominator is that number. Remember that we must also multiply the numerator for the fraction to remain equivalent to its original value.

Now, we can simply add our numerators.

We know that he needs

gallons of paint, but this is not in the most simplified format. To simplify, we need to turn our improper fraction back to a mixed number. To do this, we need to divide our numerator by the denominator to create our whole number, and the remainder becomes our new numerator.

Using that logic, we can see that the painter needs exactly
gallons of paint.
Answer: It is 3.81886792453 times larger
Step-by-step explanation: 2 x 1012 is 2024
5 x 106 is 530
so take 2024 and divide it by 530 and you get 3.81886792453
in case you were wondering this rounds to 3.82
hope this helps and mark me brainliest if you can
