Answer:
Step-by-step explanation:
Lets call the calories in one cup 'x'
so (3/4)x=90
Solving for x:
x=(90)/(3/4)
x=120
Now for 4 cups:
(4)(120)=?
480 calories in 4 cups of cereal
Answer:
208
Step-by-step explanation:
{ed}-{3cb}+{4ba}-{2ea} = {(-15)*(-6)} - {3*5*(-2)} + {4*(-2)*4} - {2*(-15)*4}
={90} - {15*(-2)} + {16*(-2)} - {8*(-15)}
= {90} - {-30} + {-32} - {-120}
= 90 (--)30 (+-) 32 (--) 120
= 90 + 30 - 32 + 120
= 120 - 32 + 120
= 88 + 120
= 208
Answer:
- 8/25 = 32/100
- 7/20 = 35/100
Step-by-step explanation:
25 and 20 have a least common multiple of 100, so that is your least common denominator.
8/25 = (8·4)/(25·4) = 32/100
7/20 = (7·5)/(20·5) = 35/100
