Mark is attempting to build muscle mass and so he needs to eat at least an additional 80 grams of protein a day. a bottle of protein water costs $3.20 and a protein bar costs $1.75. the protein water supplies 27 grams of protein and the bar supplies 16 grams. he has $10 dollars to spend. let w represent the number of bottles of protein water mark drinks and let b represent number protein bars he eats. write a system of inequalities to model this situation.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

1. she sold more on day 2 because if you turn .85 into a fraction{85/100} and you give 7/9 and 85/100 the same denominator{180} you can see which one has the bigger numerator and that one will be the most sold.

2. yes it is in simplest form, because if you look at 38 and 53 's greatest common factor, you cant find one so you cant reduce it

3. no, this is not a prime factorization because the numbers are not all prime numbers, the correct prime factorization is:   2 x 5 x 2

4.   in 12 days he will run and play trumpet again

work 4 4: 123123123123

                123412341234     in 12 days he will play the trumpet and run on the same day
