Answer:
Dan drank 1 3/8 ths of the bottle of water
Step-by-step explanation:
since the question is asking how much water he drank altogether, it wants you to add
so
7/8+4/8=11/8
Dan drank 11/8 ths of the bottle of water (1 3/8)
70, Multiply 5 pieces by 12 friends and you get 60, then add the 10 pieces he originally took out, and you get 70
You would change the whole number to a fraction by putting it over 1 and make the mixed number an improper fraction by multiplying the whole number part of the mixed number by the denominator and then and the numerator
2×+y=0,
×-y=6
Add the 1st to the 2nd equation==> 3x +y-y=6+0==> 3x=6 & x=2
Plug 2 into any of the equation & you will get y=-4
Answer:
7a........they are similar because none of the sides are equal
