How do you do 18+2x=-8x+6(7+3x)

1 answer:

3 0

If this is a simultaneous equation then:
you should simplify it to get 18+2x=-8x+42+18x
Then simplify again and you get: 18+2x=10x+42
Next if you minus 2x from both sides you get: 18=8x+42
After that you minus 42 from both sides to get: -24=8x
Finally, divide both sides by 8 and you get: -3=x

Answer:

Step-by-step explanation:

Look at the figure attached below, we know that the area of the cone is the sum of area of circle part and cone part of the figure.

to find the surface area of the cone, first measure the radius of the base and find the area of the circle part by formula $\pi r^2$ . Then measure the side (slant height) length of the cone part and find the area of the cone part by the formula $\pi rl$ .

Now the surface area of the cone is circumference of the circle plus area of the cone part.

i.e. $surface\ Area\ of\ the\ cone=\pi r^{2}+\pi rl$

From the above discussion we concluded that surface area of the cone does not depend only on the circumference of the base but also we need side length of the cone part as well thus all cones with a base circumference of 8 inches will not have the same surface area.

ll the members of a construction crew work at the same pace. Six of them working together are able to pour foundation in 22 hour

Cloud [144]

Answer:

44 hours

Step-by-step explanation:

Decreasing the people by a factor of 2 means we have 3 people

The job takes 6* 22 = 132 people hours

When we decrease the people, it will take more hours

132 people hours = 3 people * t hours

Divide each side by 3

132/3 = 3t/3

44 = t

It will take 44 hours
