Answer:
2.9
18 
Step-by-step explanation:
Let's say x = 16. In the equation 4 + x(3/x) then you use 16 instead of x. So it would look like 4 + 16(16/3). 4 plus 16 times 16 divided by 3.
Answer:
x
Step-by-step explanation:
7x+18−6(x+1)−12
start out with distributive property
7x+18+(-6x)+(-6)+(-12)
then add the common things together
x+0
answer is just x, or infine answers, you could put in anything for x
If you would like to order the following numbers from least to greatest, you can do this using the following steps:
<span>- 40, 1250, - 6.44, 0.2
</span>- 40 < - 6.44 < 0.2 < 1250
The correct result would be <span>- 40 < - 6.44 < 0.2 < 1250.</span>
Adults = x
Students = y = x + 40. 40 more student than adult
Adult = $8, Student = $6
Total for Adults = 8*x = 8x
<span>Total for students = 6*y = 6y
</span>
Total = $1920
8x + 6y = 1920
Hence system of equations are:
<span>y = x + 40
</span>
<span>8x + 6y = 1920</span>
