The number is 5.

Step-by-step explanation:

Let,

x represent the unknown number.

According to given statement;

add five to twice a number the results is fifteen

2x + 5 = 15

Subtracting 5 from both sides

$2x+5-5=15-5\\2x=10$

Dividing both sides by 2

$\frac{2x}{2}=\frac{10}{2}\\x=5$

The number is 5.

Answer:

C. 2

Step-by-step explanation:

To solve slope, the formula is $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$ . 9-3 is 6 and 5-2 is 3. So simplify 6/3 to 2.

Hope it's correct!

Clint is in study hall reading the hunger games after 20 minutes he is on page 151 after 45 minutes he's on page 181 how many pa

Mademuasel [1]

After 20 minutes Clint is on page = 151

After 45 minutes Clint is on page = 181

Time slot = $45-20=25$ minutes

Difference in pages in 25 minutes = $181-151=30$ pages.

Lets suppose Clint is reading each page at same pace.

So , In 25 minutes, he can read = 30 pages

In 1 minute he can read = $\frac{30}{25}=1.2$ pages

Initial time is 20 minutes, so he can read the number of pages in 20 minutes = $20\times1.2=24$

So, number of pages Clint read prior to study hall were =

$151-24=127$ pages.

2 hexagons are similar. if the ratio of their perimeters is 8:5, and a side of the larger hexagon measures 32 cm. find the lengt

ICE Princess25 [194]

Answer:

20 cm

Step-by-step explanation:

An hexagon has 6 equal sides therefore its perimeter is obtained by summing up all the values of the 6 sides

For the bigger hexagon, the perimeter = 32 + 32 + 32 +32 + 32 + 32

or 6 *32

= 192 cm

Next, we'll calculate the perimeter of the smaller hexagon

Since their perimeters are in the ratio 8: 5

Let x represent the perimeter of the smaller hexagon

This gives;

8 : 5 = 192 : x

change to fraction

8/5 = 192 /x

cross multiply

8x = 192*5

8x = 960

Divide both sides by the coefficient if x which is 8

x = 120 cm

Since all sides of an hexagon are equal, we'll simple divide the value of the perimeter by the number of sides of the hexagon

120/6

20 cm

Therefore, the length of the corresponding smaller hexagon is 20 cm
