Answer:
b = 72
c = 36
d = 144
Step-by-step explanation:
As every angle in the pentagon are equal (the lines inside every angle mean they are equal), angles on a straight line must add up to 180° ∴
A = 108°
108 + b = 180
180 - 108 = b
72 = b
As the top left angle of the triangle is also on a straight line with one of these angles, the value of this angle is also 72°.
All angles in a triangle must add up to 180° ∴
72 + 72 + c = 180
144 + c = 180
c = 180 - 144
c = 36
Angles on a straight line must add to 180° ∴
d + c = 180
d + 36 = 180
d = 180 - 36
d = 144
Hope this helps!
Answer:
First, denote the number of dimes as x, and the number of quarters as y.
Since the total number of coins equals 61, we can write the following equation: x + y = 61
Since the total value of the coins equals $10.90, and we know that a quarter is worth $0.25 and a dime is worth $0.10, the total value can be expressed as a function of the number of quarters and dimes: $0.10*x + $0.25*y = $10.90
Now, we have two equations and two variables, meaning we can solve the 2x2 system!
Rewrite the first equation in terms of x: x = 61 - y
Now substitute this expression into the second equation: $0.10*(61-y) + $0.25*y = $10.90
Solve for y: $.15*y = $4.80, y = 32
Substitute back into the first equation to get x: x = 29
She indeed has 3 more quarters than dimes since 32-29= 3, so we did it right (:

Answer:
3 socks
Step-by-step explanation:
The number of socks in the box does not matter. There are only 2 choices of socks in the box. So, if you take out 3 random socks from the box, you're guaranteed a pair.
