Answer:

Complex numbers are numbers in which the real component and the imaginary part of the number are both represented. The numbers in standard form will be a + bi, where a is the real part and bi is the imaginary part. An example of a complex number would be 3 +5i. 3 is the real part, and 5i is the imaginary part.

Y = 1.10x + 5.00 <br> y = 1.50x + 3.00<br> (substitution)

nataly862011 [7]

Solving the system of equations $y = 1.10x + 5.00\\y = 1.50x + 3.00$ we get x=5 and y=10.5

Step-by-step explanation:

We need to solve the system of equations by substitutions.

The system of equations given are:

$y = 1.10x + 5.00\\y = 1.50x + 3.00$

Let:

$y = 1.10 x+5.00\,\,eq(1)\\y = 1.50 x+ 3.00\,\,eq(2)$

Putting value of y from eq(2) into eq(1)

$1.50 x+ 3.00=1.10 x+5.00\\1.50 x-1.10 x=+5.00-3.00\\0.4x=2.00\\x=2.00/0.4\\x=5$

So, value of x=5

Now putting value of x in eq 1 to find value of y:

$y = 1.10x + 5.00$

$y = 1.10(5) + 5.00$

$y = 5.5 + 5.00$

$y = 10.5$

So, value of y is 10.5

Solving the system of equations $y = 1.10x + 5.00\\y = 1.50x + 3.00$ we get x=5 and y=10.5

A 70-meter path surrounds a rectangular garden. The width of the garden is two-thirds its length. Find the length and the width.

bagirrra123 [75]

$width=\frac{2}{3}length\\\\
70=2width+2length\\\\
70=2length+2(\frac{2}{3}length)\\\\
70=2length+\frac{4}{3}length\\\\
70=\frac{10}{3}length\ \ | divide\ by\ \frac{10}{3}\\\\
70*\frac{3}{10}=length\\\\
length=21m\\\\
width=\frac{2}{3}*21=14m
