Answer:

Step-by-step explanation:

x=student tickets y=general admission

We can write the two following equations

x+y=190

4.5x+6y=996

I am going to solve this through substitution

We first need to get a variable by itself

x+y=190

x-190= -y

-x+190=y

We can plug this value in for y into the second equation

4.5x+6(-x+190)=996

4.5x-6x+1140=996

-1.5x= -144

x=96

Now that we know that x=96 we can plug this value into any of the two beginning equations and solve for y

96+y=190

y=94

In an automobile parts factory, for every 175 carburetors 3 are found to be defective. At that rate how many carbureatots out of

Furkat [3]

Answer:

At the same rate 18 carburetors out of 1,050 could be expected to be detective.

Step-by-step explanation:

The number of carburetors tested = 175

Defective pieces out o f 175 = 3

So, ratio of defected to tested = 3 : 175

Now, the number of carburetors tested in second batch = 1,050

Here, let the defective pieces = m

So, by the Ratio of Proportion,

$\frac{3}{175} = \frac{m}{1050}$

or, $m = \frac{1050 \times 3}{175} = 18$

⇒ m = 18

Hence, at the same rate 18 carburetors out of 1,050 could be expected to be detective.
