Answer:

7x-14=2x+11

Step-by-step explanation:

Collect like terms

7x-2x=11+14

5x=25

Divide both sides by the coefficient of x(5).

x=25/5

x=5

Answer:

x=5

Step-by-step explanation:

The first thing we need to do in this equation is to get both of the x variables on the same side.

How do we do this you might ask? Well, need to cancel out the 2x so all we have left is one x variable. We can do this by subtracting 2x from each side.

The important thing to remember when solving equations like these is that whatever you do to one side, you MUST do to the other side.

2x-2x is 0 so that cancels out the 2x on the right side. 7x-2x=5x so we are left with that for our left side.

Now, we have to get rid of the constants (the non-variable numbers)

Let’s cancel out the 14 on the left side so the x is still by itself.

Add 14 to -14 to cancel it out. Do the same to the right side. 14+11=25 so that 25 is what we are left with on the right side.

Our equation becomes 5x=25

Now we have to completely isolate the x with no coefficient. We do this by dividing 5 by each side. But remember the rule, whatever you do to one side, you must do to the other. So we divide 25 by 5 as well.

5x/5 is x and 25 divided by 5 is 5

So our final answer is…

X=5

Hope this helped and please award brainliest.

Have a great day!

Ralph the monkey is looking down at a 59° angle from the top of a tree. There are bananas on the ground 12.4 ft from the base of
aliya0001 [1]

This forms a right angled triangle and Ralph flies down the hypotenuse x,

so using trigonometry:-

sin 59 = 12.4 / x

x = 12.4 / sin 59

= 14.47 feet to nearest hundredth.
