Use a common denominator to find negative 2/3 plus negative 4/5

or 1

step-by-step explanation:

a common denominator between 3 and 5 is 15

first to get our denominator in the fraction to 15 we need to multiply by 5 so 2 × 5 = 10 and 3 × 5 = 15

this makes our new fraction

now we need to get our denominator in the fraction to 15 so we need to multiply by 3 so 4 × 3 = 12 and 5 × 3 = 12

this makes our new fraction

our new equation with common denominators is now + = coming out to be

to make this into a mixed fraction we know 22 only goes into 15 once with 7 left over so our mixed fraction is 1

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
