Answer: -2/3
Step-by-step explanation: The slope has a positive and negative number so i knew it wasnt 2/3 but i got it correct when i put -2/3
Answer:
94
Step-by-step explanation:
first solve for x:
3x+22+3x+14= 180
6x+36= 180
6x= 144
x= 24
next fill the equation for angle 4 back in with x and solve:
3(24)+22=<u> </u><u>94</u>
This is the concept of simultaneous equations; We are required to create the equations modelling the above information.
Suppose the number of movie tickets was x and the number of meal tickets was y.
Therefore;
Total number of tickets was:
x+y=22
Total amount earned was:
0.5x+2y=25
The simultaneous equations representing the information is:
x+y=22
0.5x+2y=25
Answer: 1/5
Step-by-step explanation: Since there are 5 blue/green marbles in the bag of 20 it would be 5/20 or 1/5.
Triangle Area = .5 * base * height
48 = .5 * (x +4) * x
48 = (.5x + 2) * x
48 = .5x^2 + 2x
.5x^2 + 2x -48 = 0
x = 8
base = 12
