Answer: check explanation

Step-by-step explanation:

Multiply both sides of equation by x(x+a)

This will get rid of those nasty fractions...cuz who likes them?

Anyways,

Now you should I think get

x(x+a)+a(ax)=a

I am pretty positive that you just distribute and solve.

You may have to factor and have to put everything as an equation set to equal=0

you try it and experiment. Sometimes you just have to try to think algebraically and creatively. Don’t get frustrated just work with it. Good luck!

Semmy [17]

Justine > Ava > Emma
12 - 7.5 = 4.5
x + (x+4.5) +(x+12) = 3x + 16.5 = 63
63-16.3 = 56.7
56.7/ 3 = 18.9
A: Emma has $ 18.9 Ava has $23.4 Justin has $30.9

Solve for r and t: 6r - 3t = 6 6r + 8t = -16

Slav-nsk [51]

6r - 3t = 6 /*8
6r + 8t = - 16 /*3

48r - 24t = 48
48r + 24t = - 48
---------------------- +
96r = 0
r = 0

t = ( -16 + 6r)/8 = - 16/8 = - 2

The figure the Floor Plan of a balcony ,it consists of △ABC and semi-circle ,

ivanzaharov [21]

Step-by-step explanation:

(a) In right triangle ABC,

$AC^2 =AB^2 +BC^2 \\ = {12}^{2} + {5}^{2} \\ = 144 + 25 \\ = 169 \\ AC = \sqrt{169} \\ \therefore \: AC = 13\: m \\ \\ AC \: is \: the \: diameter \: of \: semicircle \\ \therefore \: r = \frac{1}{2} \times AC = \frac{1}{2} \times 13 = 6.5 \: m \\ Circumference \:of \:semi-circle \\ C = \pi \: r = 3.14 \times 6.5 = 20.41 \:m\:$

Perimeter of Balcony = 12 + 5 + 20.41 = 37.41 m

(b) Area of balcony

$=\frac{1}{2}\times 12\times 5+\frac{1}{2} \pi r^2 \\\\=\times 6\times 5+\frac{1}{2} \times 3.14\times (6.5)^2 \\\\=30+\frac{1}{2} \times 3.14\times42.25\\\\= 30+\frac{1}{2} \times 132.665\\\\= 30 + 66.3325\\\\= 96.3325 \:m^2 \\\\\approx 96. 33\:m^2$
