A,c,d, and e. just plug each number into x. Then see if it is less than 132.
Answer:
Answer below
Step-by-step explanation:
Angle C can be found using triangle properties of subtracting all the known angles
C = 180 - 86 - 31
=63 degrees
Now we can solve for everything else using sine law
b = 5.16 m
c = 8.93 m
Answer: there are eight bicycles and 7 tricycles.
Step-by-step explanation:
Let x represent the number of bicycles that are there.
Let y represent the number of tricycles that are there.
There are a total of 15 bicycles and tricycles. This means that
x + y = 15
A bicycle has 2 wheels and a tricycle has 3 wheels. There are 37 wheels all together if we count them up. This means that
2x + 3y = 37- - - - - - - - - - - - - 1
Substituting x = 15 - y into equation 1, it becomes
2(15 - y) + 3y = 37
30 - 2y + 3y = 37
- 2y + 3y = 37 - 30
y = 7
x = 15 - y = 15 - 7
x = 8
Answer:
6
Step-by-step explanation:
slope= m= y-intercept/x-intercepts
1/2= -7-2/a-4a
1/2= -9/-3a
1/2 = 3/a
a = 6
