Answer:

x=15

Step-by-step explanation:

<GCB=180-5x

<EBA=9x

<DAC=8x

The sum of the three exterior angles equals 360.

(180-5x)+9x+8x=360

180-5x+9x+8x=360

-5x+9x+8x=360-180

12x=180

x=15

Step-by-step explanation:

Answer:

y = 2

Step-by-step explanation:  divided both from each side

The required equivalent ratio of the given ratio is 3/5.

Given that,
The ratio that is equivalent to 9 to 15 is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,
Mentioned ration,
= 9 / 15
Reducing the expression by eliminating the common factors
= 3 / 5

Thus, the required equivalent ratio of the given ratio is 3/5.

Answer:

16 miles

Step-by-step explanation:

From the question given above, the following data were obtained:

Miles per week for training = 26 miles.

In the 5th week:

Ratio of miles ran to miles Walked is 8:5

Thus, we can obtain the miles ran by Nash in the 5th week as follow:

Ratio ran = 8

Ratio walked = 5

Total ratio = 8 + 5 = 13

Miles per week for training = 26 mile

Mile ran in the 5th week = 8/13 × 26

Mile ran in the 5th week = 8 × 2

Mile ran in the 5th week = 16 miles

Therefore, Nash ran 16 miles in the 5th week of training.

Answer:

44

Step-by-step explanation:

you would add 15+15 and 12+12 because it is rectangular meaning there are 4 sides 2 for the y angle and 2 for the x angle

(3 + 2i) - (5 - 7i)

Distribute the - sign

3 + 2i - 5 + 7i

Combine like terms

-2 + 9i

Answer:

r = t - u - s

Step-by-step explanation:

To solve for r in terms of s, t, and u, means to have r on one side and have t, u, and s.

t = u - s + r

t - u = s + r

t - u - s = r

Answer:

OT

Step-by-step explanation:

added to so true

Answer:

true

Step-by-step explanation:

$518.5 = $375 + $41x

Now that we have our equation, let's solve for the # of hours

Subtract $375 from both sides

$143.5 = $41x

Divide both sides by $41

3.5 = x

The number of labor hours was 3.5

Answer:

13 glasses

Step-by-step explanation:

Given:

Amount of of lemonade available = 20⅜ cups

Amount of lemonade per guest = 1½ cups

Required:

Number of glasses to be filled

SOLUTION:

Number of glass to be filled = amount of lemonade available ÷ amount of lemonade per guest

= 20⅜ ÷ 1½

Change both mixed fractions to improper fractions

= [tex] \frac{163}{8} [/tex] ÷ [tex] \frac{3}{2} [/tex]

Flip the fraction on your right upside down and change the division to multiplication

[tex] = \frac{163}{8} * \frac{2}{3} [/tex]

[tex] = \frac{163*2}{8*3} [/tex]

[tex] = \frac{163*1}{4*3} [/tex]

[tex] = \frac{163}{12} = 13.58 [/tex]

Number of glasses that would be filled is roughly 13 glasses.
