7 0

Step-by-step explanation:

The GCF of 28 and 80 is 4.

<u>Distribute 4 for 28 and 80, then solve:</u>

4(7) + 4(20) = 28 + 80

4(7 + 20) = 28 + 80

4(27) = 28 + 80

108 = 80 + 28

An animal shelter spends three dollars per day to take care for each bird and seven dollars per day take care for each cat Alexa
NikAS [45]

Answer:

There were 16 birds  at the shelter on Wednesday.

Step-by-step explanation:

Number of cats and birds on Wednesday = 34

let the number of birds on Wednesday = b

Then number of cats = (34 -b)

The rate of taking care of each bird in shelter = $3

The rate of taking care of each cat in shelter = $7

Total amount spent by shelter on Wednesday = $174

So, according to the question

b x ($3)  +  (34 -b) ($7) =  $ 174

or,  3b + 238 - 7b = 174

or, 4b = 64

⇒ b = 64/4 = 16

Hence, the number of birds in shelter on Wednesday = b = 16

and  Number of cats = 34 - 16 = 18

What is the value of x?
Vilka [71]

Answer:

x = 58

Step-by-step explanation:

The angle formed by two secants = 1/2(difference of intercepted arcs)

51 = 1/2 (160 - x)

Multiply each side by 2

51*2 = 2*1/2 (160-x)

102 = 160-x

Subtract 160 from each side

102-160 = 160-160-x

-58 = -x

Multiply each side by -1

58 =x
