4+36=40
Answer with explanation:
Consider a Rectangular room, in which four people are residing and another congruent room,in which six people are dwelling.
If Area Occupied by two rooms are same
Then, Area occupied by each person in first room,if there are four person in first room, if represented in terms of fraction is equal to one fourth
.
And, Area occupied by each person in second room,if there are six person in second room, if represented in terms of fraction is equal to one sixth
.
So,→→ Area occupied by each person in which four people are residing>Area occupied by each person in which six people are residing.
→→So,Fraction with a lesser denominator has larger pieces(Larger area) than the fraction with a greater denominator smaller pieces(smaller area).
The last one, d, 2/3 < g < 2
3b+5r=2 gallons of cabbage red
1r+7b=2gallons of egplant
1 gallon of cabbage sells for 22 (means 2 gallos is 44)
1 gallon of egplant is 26 (means 2 gallons is 52)
3b+5r=44
r+7b=52
r+7b=52
miinus 7b from both sides
r=52-7b
sub 52-7b for r in othe equestion
3b+5(52-7b)=44
3b+260-35b=44
-32b+260=44
minus 260 from both sides
-32b=-216
divide both sides by -32
b=6.75
r=52-7b
r=52-7(6.75)
r=52-47.25
r=4.75
3blue+5r=2gallons
5+3=8
8units=2gallons
4units=1gallon
1unit=1quart
therefor
1 quart of blue paint is $6.75
1 quart of red paint is $4.75
