Answer:

25

Step-by-step explanation:

  1. 100 people -65 people to get the women number which gives us 35
  2. 60 people employed weekly
  3. all of women employed
  4. the rest will be men
  5. because there are only male and female and all the females are not 60 in number
  6. so if there is 60 people employed weekly and thirty five of the the place are taken by the females 60-35 will be 25 left
  7. as we know there are only males unemployed so the 25 peoples are male

Answer:

25.

Step-by-step explanation:

The number of women employed = 100 - 65 = 35.

So the number of men paid weekly = 60 - 35

= 25.

Simplify the complex fraction. 8/5 divide by 6 3/4 *
hichkok12 [17]

Step-by-step explanation:

\frac{8}{5}÷6\frac{3}{4}

First, simplify the 6\frac{3}{4} to an improper fraction, which is:

\frac{27}{4}

Next rewrite the equation using the improper fraction:

\frac{8}{5}÷\frac{27}{4}

Now, in order to divide the fraction, we will need to flip the second fraction over, and then multiply the two fractions together. A great way to remember this is the phrase <em>Copy Dot Flip - </em>Copy the first fraction, put a dot for multiplication, and flip the second fraction.

\frac{8}{5}·\frac{4}{27}

Finally, multiply together and simplify/reduce if needed:

<u>The final answer is </u>\frac{32}{135}<u> and no simplification or reduction is needed</u>

Solve the system of equations. y = 2x y = x 2 – 15
inn [45]

Answer:

D. (–3, –6) and (5, 10)

Step-by-step explanation:

The system has equations:

y=2x...(1)

and

y=x^2-15...(2)

Equate both equations;

x^2-15=2x

Rewrite in standard form:

x^2-2x-15=0

We factor to obtain:

(x+3)(x-5)=0

By the zero product principle;

(x+3)=0,(x-5)=0

\implies x=-3,x=5

When x=-3, y=2(-3)=-6

This yields the ordered pair (-3,-6).

When x=5, y=2(5)=10

This yields the ordered pair (5,10).

The correct choice is D.

Write a real world problem for the following equation:<br> 80-3x=53
Afina-wow [57]

Answer:

x=9

Step-by-step explanation:

Step 1: Simplify by both sides of the equation.

80-3x=53

80+-3x=53

-3x+80=53

Step 2: Subtract 80 from both sides.

-3x+80-80=53-80

-3x=-27

Step 3: Divide by both sides by 3.

-3x/-3 = -27/-3

x=9
