I: x = –2y – 2
II: 2x + 3y = –6
substitute I's x (x = –2y – 2) definition into II:
2*(-2y-2) + 3y = –6
-4y-4+3y=-6
which is the last option
First, you want to find out how many pints are in a gallon, which are 8.
So, 8 x .55 = 4.40
Muriel would save $0.45 by buying 1 gallon instead of multiple pints.
Answer:
a = 7
Step-by-step explanation:
This is a special trig triangles. Special trig triangles are identified by their angle measures and their sides have a unique relationship. This is a 30 - 60 - 90 triangle which has sides 1 - √3 - 2 or multiples of this. This means all 30 - 60 - 90 triangles have side lengths with the pattern 1 - √3 - 2. Here the triangle has a - 7√√3 - 14. The value of a is 7 since 7*√3 = 7√3 and 2*7 = 14.
