A,C,D those were the answers i put and they were correct.
Plug 4x=9 in for y:
10x=18-2(4x+9)
10x=18-8x-18
10x=-8x
18x=0
x=0
now plug 0 in for x:
y=4(0)+9
y=9
to check, plug x and y back into one of the equations to make sure they are right:
10(0)=18-2(9)
0=18-2*9
0=18-18
0=0
Answer:
<em>John has 11 photos on his phone</em>
Step-by-step explanation:
<u>Equations</u>
Megan has 99 photos on her phone and John has p photos on his phone. It's given Megan has 9 times as many photos on her phone as John has. This leads to the following equation:
99 = 9p
Dividing by 9:
p = 99/9 = 11
John has 11 photos on his phone
The answer is both a and b, but I think you meant to switch the greater/less signs, so then it would be x > 0.
