9 times 9 = 81 6 times 6 =36 so 36 plus 18
6+18/3*4 PEMDAS 18/3=6 6+6*4 6*4=24 24+6= 30. 30 is the final answer
Answer:
The system of equations are;
3x + 2y = 170
4x +6y = 360
Step-by-step explanation:
Form simultaneous equations and solve
Let x=price of children tickets
Let y=price of adult tickets
The Brown Family paid $170 for 3 children and 2 adults , this forms the equation as:
3x + 2y =$ 170
3x + 2y = 170 --------------------------equation (i)
The Peckham Family paid $360 for 4 children and 6 adults.
4x + 6y = $360
4x +6y = 360 ---------------------------equation (ii)
Solving the equations by graph will give value of x=30 and y=40
The price of children tickets was $30 and that of adults was $40
Answer:
1.8-9
2. most often
3.12-13
4.12-13
Step-by-step explanation:
i got it correct thats all i got to say
A) is ok; its slope is the neg. reciprocal of the given slope 4, as is required for
perpendicular lines.
B) not feasible; its slope is +1/4, not the negative reciprocal of 4 (-1/4).
C) OK
D) OK (slope is -1/4)
