Answer:
0.9
Step-by-step explanation:
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
For this case we have the following expression:

The first thing we must do is to rewrite the expression as the product of two binomials.
To do this, we add similar terms.
We have then:

Then, doing distributive property we have:

Adding similar terms:
Answer:
The simplified expression is:
Yeah Im pretty sure it is
This problem can be solved by writing a conditional equation.
(8*1.5)+6= d
12+6= d
d= 18GB
Check- 18-12= 6GB
