so Im not sure about how an equation for this would look but im assuming her mom doesnt pay unless a full 5 is completed, in that case her mom donates $1.6, in the case less than 5 is still donated for we make .16 * 12 which is $1.92
3(-2x+6) -x+3=0
-6x+18-x+3=0
-7x+21=0
-7x=-21
x=3
y=-2x+6
y=-2(3)+6
=6-6
=0
answer: (3,0)
The blue ball is more than the red ball because there isn't anything smaller than kilograms
Answer:
RVS is equal to 180 - 26 degrees, or 154 degrees.
Bonus: I assume the next part of the question asks you to solve for x, where x is equal to that angle. If so, then the answer is 15:
154 = 10x + 4
150 = 10x
x = 15
