HELP simple question

lawyer [7]

Answer:

I think it’s step 2 where she distributed the exponents incorrectly but she got it right so since no explanation is really needed then I guess it’s step 2.

step 1 where she divided 5 on both sides. Step 3 is also correct since the answer is 0. so step 2 had the mistake.

An equilateral triangle has sides of length(3k-2)units. A regular pentagon(5 sides) has sides of (2k+0.5)units. If the perimeter

Vitek1552 [10]

The length of side of triangle is 5 units and length of side of pentagon is 1.5 units.

SOLUTION:

Given, An equilateral triangle has sides of length $(3k-2)$ units.

Then, perimeter of the triangle will be $3 \times(3 k-2)=9 k-6$

A regular pentagon (5 sides) has sides of $(2k+0.5)$ units.

Then, perimeter of the pentagon will be $5 \times(2 k+0.5)=10 k+2.5$

We have to find the dimensions of each shape . Now, the perimeter of the triangle is twice the perimeter of the pentagon,

So, $\text {perimeter of triangle} = 2\times \text{perimeter of pentagon}$

$\begin{array}{l}{\rightarrow 9 k-6=2(10 k+2.5)} \\\\ {\rightarrow 9 k-6=20 k+5} \\\\ {\rightarrow 20 k-9 k=-6-5} \\\\ {\rightarrow 11 k=-11} \\\\ {\rightarrow k=-1}\end{array}$

Then, length of side of triangle $= 3(-1)-2 = - 5$

Length of side of pentagon $= 2(-1) + 0.5 = - 1.5$

We have to neglect, negative sign as lengths can’t be negative. Even if we change the sign above all conditions are satisfied.

Solve the Equation!! Z - 2/3 = 1/8

olga_2 [115]

$z- \frac{2}{3} = \frac{1}{8} \\\\ z = \frac{1}{8} + \frac{2}{3} \\\\z = \frac{3}{24} + \frac{16}{24}\\\\z = \frac{3+16}{24} \\\\z= \frac{19}{24}$
