The value of a certain stock increase by 1 1/4% explain how to write one and 1 1/4% as a fraction in simplest form

I must confess that I was about to pass this question by, but I was captured by the respectful and dignified way in which you asked for help.

A careful reading of the problem gives you two equations in two unknowns, which you can then solve as simultaneous equations. Here's how it looks:

Call 'C' the price of the senior Citizen ticket.
Call 'S' the price of the Student ticket.

On the first night . . . 10 C + 12 S = 208

On the second night . . . 8C + 3 S = 74

Those are your two simultaneous equations. Now the idea is to multiply or divide each side of one equation in such a way that when you add or subtract it from the other equation, one of the variables will become a zero quantity ... you'll be left with an equation in one variable, which you can easily solve. THEN, knowing the value of one variable, you can put it back into one of the original equations,and find the value of the other variable.

This all sounds more complicated than it is. Here's how it goes:
We have . . .

10 C + 12 S = 208 and
8C + 3 S = 74

I'm going to multiply each side of the second equation by 4, and then write it under the first one:

10 C + 12 S = 208
32 C + 12 S = 296

Now, subtract the lower equation from the upper one, and you get . . .

- 22 C + 0 = - 88

Divide each side of this one by -22 and you have C = $4.00 .

THAT's what you need, to blow the whole problem wide open. Knowing
the value of 'C', let's substitute it into the equation for the first night:

10 C + 12 S = 208

10(4) + 12 S = 208

40 + 12 S = 208

Subtract 40 from each side : 12 S = 168

Divide each side by 12 : S = $ 14.00 .

Finally, as we look over our results, and see that Students have to pay $14 to see the show but Seniors can get in for only $4 , we reflect on this ... or at least I do ... and realize that getting old is not necessarily all bad.

PLS 40 points

Pavlova-9 [17]

Step-by-step explanation:

Let $p1$ be the point $(-1,4)$

Let $p2$ be the point $(3,-4)$

The equation of the line passing through two points $p1=(x_{1},y_{1})$

and $p2=(x_{2},y_{2})$ is $\frac{y-y_{1}}{x-x_{1}} =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

substituting $p1,p2$ in the above equation yields

$\frac{y-4}{x-(-1)}=\frac{-4-4}{3-(-1)}$

which when simplified gives $\frac{y-4}{x+1}=\frac{-8}{4}$

which when further simplified gives $2x+y=2$

A rectangular tile has a decorative pattern of 3 equal-sized squares, each of which is divided into 2 same-sized triangles. If M

Andrew [12]

72 triangles will be displayed I believe....

All you do is multiply 2 times 36 and you get 72. Because there are 2 triangles in one square, so 2*36.

Hope this Helps!
