For this all you need is to balance the equation out with the variables (a) on one side and the number on the other. Also remember that what you do to one side you do to another. So here we have 4=3a-14. You should add the 14 to both sides, on one side to cancel out the 14 and add the 14 on the other side to balance it out. Now you have 18=3a. Divide by 3 on both sides to isolate the variable a and you have your answer. A=6
Answer:
A = 3,-1
B = 2, 4
C = -3, 0
D = 1,-1
Step-by-step explanation:
First, you should know that the first number is the x axis, and the second number is the y axis. You ALWAYS find the x axis first. Next, you start from the origin point, 0. 0 is where the two lines meet. Starting from 0, you move the point three spaces to the right, and one down to get to point A. So, the coordinate would be 3,-1. For point B, you would move two points to the right, and 4 down. That brings you to 2,4 the coordinates for point B. Do the same things for C and D. Go three spaces left, and stay there. That would be -3,0. For D, go right 1, and one down. Remember UP and RIGHT = Positive, DOWN and LEFT = Negative. Hope this helped!
Answer: 8+1.5+1.5=11 10+1.5+1.5=13 11+13+11+13=48
Step-by-step explanation:
First multiply 180 and 25 which is 4500.
Then divide by 17 which should be approximately 264.71
