Answer:
x=6 ; y=1
Step-by-step explanation:
Let 'y' stand for the speed of the wind and 'x' stand for the speed of Santa. We will use the general equation (distance)=(rate)(time) to write two equations from the given information:
With the wind:
35=(x+y)(5)
Against the wind:
35=(x-y)(7)
Now we have two equations and two unknowns so we can solve for x and y. We get:
x=6 miles/min
y=1 miles/min
a < - 13
The number line shows an open circle at negative 13 indicating that a cannot equal negative 13. The arrow on the red section ( the solution ) is pointing to the left away from negative 13 indicating a has values less than - 13
a < - 13 is the inequality representing the solution
note if the circle was filled in this would indicate a is equal to negative 13
Answer:
2.50 c+7.50 d=182.50
2.5 c+7.5 d= 182.5
c+3 d=73
c+d=37
subtract
2d=36
d=18
c=37-18=19
number of cats=19
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
72 divided by 6=12
six sides on a cuboid
volume of a cuboid is 72
so divide 72 by 6
