Answer:

90, 90, 90, 135, 135

Step-by-step explanation:

The sum of the measures of all angles is 540 deg.

The measures of the angles are: x - 45, x - 45, x, x, x - 45.

Add the expressions of the measures of the angles and set equal to the sum of the measures, 540 deg. Then solve for x. Then use the value of x to find each angle measure.

x + x + x - 45 + x - 45 + x - 45 = 540

5x - 135 = 540

5x = 675

x = 135

x - 45 = 135 - 45 = 90

Answer: 90, 90, 90, 135, 135

2.318181818 repeating as a mix number

natali 33 [55]

As you can see, 18 is a constantly repeating number in this situation. So take out the 2.3 to get 0.01818..... To make infinitely long rational numbers with repeating digits into a fraction, put it over 99. so 0.1818...... would be 18/99. But since it is 0.0181818...., you have to put 18 over 990. 18/990 is 2/110, which is 1/55. Now you have to add 2.3 to 1/55 which will be 2 7/22

9. The ticket at right has a perimeter of 42 cm.

Liula [17]

Perimeter simply represents the sum of all side lengths of a shape. The length of the missing side of the ticket is 5 cm; the length of gold line on each ticket is 20 cm, and 2 bottles of gold ink are required to draw gold lines on 200 tickets.

I've added the image of the ticket as an attachment.

(a) The missing side length

From the attachment, the 4 unknown side lengths are equal. Represent this side length with L.

So, we have:

$Perimeter =2\times 11 + 4 \times L$

This gives

$2\times11 + 4 \times L = 42$

$22 + 4 \times L = 42$

Collect like terms

$4 \times L = 42-22$

$4 \times L = 20$

Divide both sides by 4

$L =5cm$

(b) The length of the gold lines

There are 4 slant lines and the length of one of the slant lines is 5 cm (as calculated above).

So, the length of the gold line is:

$Gold = 4 \times L$

$Gold = 4 \times 5cm$

$Gold = 20cm$

(c) The number of gold ink bottles.

$n = 200$ --- number of tickets

The length of all gold line in the 200 tickets is:

$Length = 200 \times Gold$

$Length = 200 \times 20cm$

$Length = 4000 cm$

$Length = 4000 \times 0.01m$ ---- convert to meters

$Length = 40m$

Given that:

$Bottle = 20m$ --- 1 bottle for 20 m

The number of bottles (n) is:

$n = \frac{Length}{Bottles}$

$n = \frac{40m}{20m}$

$n = 2$

Hence, 2 bottles of gold ink are enough.

timofeeve [1]

Answer:

${ \tt{y = 8 - 3x}} - - - (i) \\ \\ = > 7x - 4(8 - 3x) = 6 \\ 7x - 32 + 12x = 6 \\ 19x - 32 = 6 \\ 19x = 38 \\ x = 2 \\ \\ = > y = 8 - 3(2) \\ y = 2$
