4/5 of his total trip is 480...
4/5x = 480
x = 480 / (4/5)
x = 480 * 5/4
x = 2400/4
x = 600 <=== total distance is 600 miles
Answer:
16
Step-by-step explanation:
because 5.5 is 22 laps and you do 22-6=16.
Answer:
12
Step-by-step explanation:
one bowl is equal to 3 sundaes. When you count the number of bowls shown in the pictograph, there are 16 bowls. Now multiply 16 by 3 to know how many sundaes there are. Since there are 4 different stores, you would have to divide 48 by 4 to get your mean(or average) value.
Math:
16 x 3 = 48
48/4 =12
Step-by-step explanation:
X=width of a coccer pitch
2x-20=length of a soccer pitch
Area (rectangule)=length x width
We suggest this equation:
x(2x-20)=6000
2x²-20x=6000
2x²-20x-6000=0
x²-10x-3000=0
We solve this quadratic equation:
x=[10⁺₋√(100-4*1*-3000)]/2=[10⁺₋√(100+12000)]/2=
=(10⁺₋110)/2
we have two solutions:
x₁=(10-110)/2=-50, invalid solution.
x₂=(10+110)/2=60
x=60
2x-20=2(60)-20=120-20=100
Solution: the length is 100 m, and the width is 60 m.
To check:
Area=100 m*60 m=6000 m²
The twice of width is =2(60 m)=120 m,
20 m less than twice its width is: 120 m-20 m=100 m=the length.
