Answer:

1, 4, 5

Step-by-step explanation:

This is the equation:

\frac{h}{30} = quotient

So because 1 and 4 are right because they both describe the quotient being of h and 30. 5 is right because fractions are really just the numerators divided by denominators (h÷30).

Answer:

The answers are 4 and 5

Step-by-step explanation:

Please keep in mind that there is a specific order in division, multiplication, and subtraction. The order does NOT matter when it is addition. The reason it was wrong was because the order was incorrect. If you look at the fraction you'll see that the unknown number was in the numerator and the 30 was in the denominator. For the answers you must follow this order to get it correctly. If you look at the other answer ( i don't wish to offend in any way.) the person put 1 in there answer and it was out of order. By that I mean it put 30 first instead of the unknown number.

I hope this helped!

Have great day!

It was recently estimated that females outnumber males by about three or two. If there are 1770 people in a county, how many of
max2010maxim [7]

GIVEN

1) Females outnumber males by 3 to 2.

2) There are 1770 people in the city.

SOLUTION

Let the number of males be x and the number of females y. Therefore, the total number of people can be written to be:

x+y=1770\text{   -----------(1)}

If there are 3 females for every 2 males, we have that:

\begin{gathered} \frac{y}{3}=\frac{x}{2} \\ \therefore \\ x=\frac{2y}{3}\text{   ----------(2)} \end{gathered}

We can substitute equation (2) into equation (1) and solve for y:

\begin{gathered} \frac{2}{3}y+y=1770 \\ \frac{2y+3y}{3}=1770 \\ 5y=1770\times3 \\ 5y=5310 \end{gathered}

Dividing both sides by 5, we have

y=1062

There are 1062 females in the county.

What is a formula for the nth term of a given sequence
IceJOKER [234]

Answer:

a_n=-12-4(n-1)

Step-by-step explanation:

The given sequence is

-12,-16,-20...

The first term of this sequence is a_1=-12.

The common difference is

d=-16--12

d=-16+12=-4

The nth term of this arithmetic sequence is;

a_n=a_1+d(n-1)

We substitute the values for the first term and the common difference to obtain;

a_n=-12-4(n-1)

6/x = x-1<br> that 6overx = x-1
Juliette [100K]
6/x = x-1

Multiply x by both sides

6= x(x-1)

Set x and x-1 equal to 6

x = 6, x = 1+6 = 7
