Answer:
Mostly answer is A but am confused btwn A and D I'll let you know when I'm sure
What word? Be more specific please
Answer:
(-5.77, 6.46)
Step-by-step explanation:
15x + 9y = 45 ----------- i
9x + 8y = 12----------------ii
Multiply equation i by 9 the coefficient of x in equ ii
And equation ii by 15 the coefficient of x in equ I
9 x 15x + 9y = 45 ----------- i
15 x 9x + 8y = 12----------------ii
135x+81y = 405
135x+120y= 180
Subtract equation ii from I
135x-135x+81y-(+120y)= 405-180
-39y=225
y = 225/-39 = -5.77
Insert the value of y in equ i
15x + 9y = 45
15x+9(-5.77) = 45
15x-51.92=45
15x = 45+51.92
15x= 96.92
x = 96.92/15= 6.46
(x,y) = (-5.77, 6.46)
x = 6.92/15
4x = student tickets, 7x = adult tickets
4(120) + 7x = 1500
480 + 7x = 1500
7x = 1020
X = 145 adult tickets
Answer:
Choice B
Step-by-step explanation:
USE PEMDAS
First do the things in the parenthesis. 2 1/3- 3/4 is 19/12
Multiply 19/12 by 1/6. You get 19/72. Add 5/24. You get 34/72. Simplify: 17/36
Please give my Brainliest I would really appreciate it!
Hope this helps!
