-3x - 3/4 = 9 helpppppppp

1 answer:

6 0

-3x - 3/4 = 9
-3x - 3/4 + 3/4 = 9 + 3/4
-3x = 9 3/4
I change 9 3/4 to improper fraction
-3x = 39/4
-3x / -3 = 39/4 / -3
X = 39/4 x -1/3 (change division to multiplication so that you can complete the problem)
X = -39/12
You can convert that if you want to -3 3/12
So x = -3 3/12
Simplify to x = -3 1/4

Solve 9(8 - x) = 3x.

bulgar [2K]

Hello - let's do this step by step. Show your work.

You're asking: 9(8−x)=3x.

Now, simplify both sides of the equation.

9(8−x)=3x

(9)(8)+(9)(−x)=3x (To do that, distribute)

72+−9x=3x

−9x+72=3x

Now, subtract 3x from both sides.

−9x+72−3x=3x−3x

Simplify,

−12x+72=0

After, subtract 72 from both sides.

−12x+72−72=0−72

−12x=−72

Last thing, divide both sides by -12.

-12x/12 = -72/-12

Divide.

Therefore, you have <u>x = 6</u> as your final answer.

A park is in the shape of a rectangle 2 miles long and 1.5 miles wide. How much shorter if you walk diaganolly across the park r

Nimfa-mama [501]

You can answer this by using Pythagoras theorem. Okay, let me draw this first.

2 miles
V
________________________
| |
| |
| | << 1.5 miles
|_______________________|

^ Assume this is the rectangle. The long side is 2 miles while the shorter side is 1.5 miles.

So, to get the shortest distance, let's cut out a triangle from the rectangle.

    /|
       / |
/ |
What we want to find is this one > / | << 2 miles
   / |
  /______|
   ^ 1.5 miles (I know the size is not logical,but imagine   it please)

So to get the diagonal length = $\sqrt{{a^{2} }+ b^{2}}$
= $\sqrt{{2^{2} }+ 1.5^{2}}$
= 2.5 miles

To calculate how much shorter = ( 2 miles + 1.5 miles) - 2.5 miles
= 3.5 miles - 2.5 miles
= 1.0 miles

Hope this help !
