x= -3/8

here's how you solve it!

first distribute the -2/3 into the parentheses and you'll get:

4-8/3x+6=11

Then add 4 and 6 together

10-8/3x=11

Then multiply the equation by 3

30-8x=33

Then move the constant to the other side and change the sign

-8x=33-30

Subtract 30 from 33

-8x=3

Then divide both sides by -8

x=-3/8

Then you are left with your answer:

x= -3/8

Hope this helps! :3

Simplify both sides of the equation.

4 −  2/3  (4x − 9) = 11

4 +  −8/3  x + 6 = 11

Distribute

(−8/3  x) + (4 + 6) = 11

Combine Like Terms

−8/3x+10=11

Subtract 10 from both sides.

−8/3x + 10 − 10 = 11 − 10

−8/3

x = 1  

Multiply both sides by 3/(-8).

(3/−8)*(−8/3  x) = (3/−8)*(1)

x =  −3/8

In Triangle XYZ, A is the midpoint of XY, B is the midpoint of YZ, and C is the midpoint of XZ.
Roman55 [17]

The perimeter of triangle ABC is 24 units

Step-by-step explanation:

If a segment joining the mid points of two sides of a triangle, then

this segment is:

  • Parallel to the third side
  • Its length is half the length of the third side

In The triangle XYZ

∵ A is the mid point of XY

∵ B is the mid point of YZ

∴ AB = \frac{1}{2} XZ

∵ XZ = 18 units

- Substitute the value of XZ in AB

∴ AB = \frac{1}{2} × 18 = 9 units

∵ B is the mid point of YZ

∵ C is the mid point of XZ

∴ BC = \frac{1}{2} XY

∵ AY = 7 units

∵ AY = \frac{1}{2} XY

∴ XY = 2 × AY

∴ XY = 2 × 7

∴ XY = 14 units

∴ BC = \frac{1}{2} × 14 = 7 units

∵ A is the mid point of XY

∵ C is the mid point of XZ

∴ AC = \frac{1}{2} YZ

∵ BZ = 8 units

∵ BZ = \frac{1}{2} YZ

∴ YZ = 2 × BZ

∴ YZ = 2 × 8

∴ YZ = 16 units

∴ AC = \frac{1}{2} × 16 = 8 units

∵ The perimeter of a triangle = the sum of the lengths of its sides

∴ Perimeter Δ ABC = AB + BC + AC

∴ Perimeter Δ ABC = 9 + 7 + 8 = 24 units

The perimeter of triangle ABC is 24 units

An arithmetic series has seven terms. the first term is 5 and the last term is 53. find the sum of the series!
Kisachek [45]
The easiest way is to use (& to memorize) the sum formula for a AP:


Sum = 1st term added to the last term & multiplied by half the number of terms
S = (a+l)n/2

S = (5 + 53)(7/2) = 203
