Answer:
7/12
Step-by-step explanation:
12 sided die has 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 as the sides.
Two digits are 10, 11, and 12.
Even numbers are 2, 4, 6, 8, 10, and 12.
So two digits or even numbers are 2, 4, 6, 8, 10, 11, and 12. (7 total numbers)
P(Two digits or even) = 7/12
85 minutes
it's c, 80 degrees
a triangle is like a straight line, but it has 3 different angles that all add up to 180 degrees
x = 11 and y = 4
Given equations are :
x+y=15 ...(1)
-2x+5y=-2 ...(2)
We need to solve the systems of equations.
Multiply equation (1) by 2.
2x+2y=30 ...(3)
Adding equation (2) and (3).
-2x+5y+2x+2y = -2+30
7y = 28
y = 4
Put the value of y in equation (1).
x+4=15
x = 11
So, the solution of the given equations are x = 11 and y = 4.
The distance from Simon's house to the beach is 137.5 miles
we know that
The speed is equal to the ratio of the distance and the time
Let
s ----> the speed in mph
x ----> the distance in miles
y ---> the time in hours
we have
substitute in the formula and solve for x
