Answer:
Number of dogs = 6
Number of burgers = 11
Step-by-step explanation:
Number of dogs = x
Number of burgers = 2x - 1
Cost of a dog = $ 1.50
Cost of 'x' dogs = 1.5x
Cost of a burger = $ 2
Cost of (2x - 1) burger = (2x -1) * 2 = 2x *2 - 1*2
= 4x - 2
Total amount collected = $ 31
1.5x + 4x - 2 = 31 {add 2 to both sides}
1.5x + 4x = 31 + 2
1.5x+ 4x = 33
5.5x = 33
x = 33/5.5
x = 6
Number of dogs = 6
Number of burgers = 2*6 - 1 = 12 - 1 = 11
Answer:
156km
Step-by-step explanation:
Given data
The red Maserati traveled at a speed of 120km/h for 5 hours one day.
Distance = speed*time
Distance= 120*5
Distance= 600km
The green Ford Pickup traveled at a speed of 74km/h for 6 hours
Distance = speed*time
Distance= 74*6
Distance= 444km
Hence the difference is
=600-444
=156km
Answer:
36, 8.5
Step-by-step explanation:
an exponent of two means that you are multiply a number by itself
so in this case you would multiply 6 by itself: 6 x 6
this gets you 36
and 8.5 doesn't change so its just 8.5
Answer:
The fraction of red guppies = 1/10
Step-by-step explanation:
Garys fish are guppies = 3/5
1/6 of them are red.
Number of red guppies = ?
To find the fraction of red guppies, we will multiply both the fractions.
Number of red guppies = 3/5 * 1/6
Number of red guppies = 3/30
Number of red guppies = 1/10
Thus the fraction of red guppies = 1/10 ....
