A certain number was multiplied by 7. 4 was taken away from the product. Finally, that difference was then divided by 9, resulti

marin [14]

Answer:

Step-by-step explanation:

To solve this, we have to work backwards. If you divide something by 9, and it equals 5, to figure out the number, we need to multiply by 9. 5*9= 45. If four was taken away, we have to add it to 45, which is 49. If a number *7 is 49, then we have to divide by 7 to get the answer. 49/7=7

Leya [2.2K]

Answer:

√64

Step-by-step explanation:

In mathematics, an expression involving the root (√) sign is regarded as a radical.

64^(1/2)

This is the same as;

√64

- √(1/2&64) This option is wrong.

- √64 This option is correct

- 1/2 √64 This option is wrong.

The pie chart shows information about voters in a election.2800 more women vote than men.

Lyrx [107]

ANSWER

The total number of voters is
$10080$

EXPLANATION

Let the
$x$
be the number of voters that are men.

Then the women will be
$x + 2800$

The total voters will be
$x + (x + 2800)$

$2x + 2800$

We now use ratio.

We can see from the diagram that,
$130 \degree$
corresponds to men.

We can write the ratio

$x:130 \degree$

Also the total number of voters corresponds to the angle in a complete circle. This will also give us the ratio,

$(2x + 2800):360 \degree$

We can therefore write the equation,

$\frac{2x + 2800}{x} = \frac{360 \degree}{130 \degree}$

$\frac{2x + 2800}{x} = \frac{36 }{13}$

We cross multiply to get,

$13(2x + 2800) = 36x$

This implies that,

$26x + 36400 = 36x$

We group like terms to obtain,

$26x - 36x = - 36400$

This implies that,

$- 10x = - 36400$

$x = 3640$

The total number of voters
$= 2(3640) + 2800$
$= 10080$

The total number of voters is
$10080$
