For the answer tot he question above, let the number of t-shirts are represented by 't'
number of sweaters are represented by 's'

cost of 1t=10 and cost of 1s=20 so
10t+20s=2000 or (factor out the 10 if you want to simplify)
10(t+2s)=10(200)
divide both sides by 2
t+2s=200

I added three non-unit fractions together to make a whole. What three fractions could that be?
Anna11 [10]

Answer:

For example \frac{2}{6}

Step-by-step explanation:

A non-unit fraction is a fraction of which the numerator is not equal to one. Additionally, the question does not state to pick three different ones and thus you can pick any fraction that when multiplied by three (since you take three fractions together) add up to a whole number (I'm picking the whole number to be one here just to make it simple), where the numerator is not equal to one of course.

For example:    \frac{2}{6}, because 3·    \frac{2}{6} =      \frac{6}{6} = 1

Infinitely many solutions can be found: for example \frac{3}{9} , \frac{4}{12} , etc

Greeley [361]

Answer:

7960

Step-by-step explanation:

PEMDAS is irrelevant since they are all addition and subtraction. You can first to 9100+990 in your head which equals 10,090. Then you can subtract 130 in you head which equals 9960. Then you subtract the final 2,000 which results in 7960.
