Two can be the same and for the most that would be two $5 bills and the third would be a $1 bill so the most he could give her is $11
Let x = speed of the first car
the second car is 12 km slower so the seconds car speed is x-12
they each drove 2 hours so 1st car = 2x
2nd car = 2(x-12)
they drove 360 km
so you have 2x + 2(x-12) = 360
solve for x
2x+2(x-12) = 360
2x + 2x-24 = 360
4x-24 = 360
4x = 384
x = 384/4
x = 96
1st car drove at 96 km per hour
slower car drove at 96-12 = 84 km per hour
6x + 7y = 59...multiply by -4
4x + 5y = 41...multiply by 6
It is the symmetric property
Answer:
Number line graph with closed circle on 12 and shading to the right.
Explanation:
if you see Ezra needs $37 and if she has less than $12 then she will not have $37. she needs exactly $12 or more. The closed circle tells us that 12 is a answer and the shading to the right means more than 12.
