Claire walked her dog 2 1/5 miles. Carson walked her dog 1 3/4 times as far as Claire did. How many more miles did Carson walk h
Anon25 [30]

The word "times" means you have to multiply.

2 1/5 times 1 3/4 is 3 17/20.

The phrase "how many more" means you have to subtract.

3 17/20 minus 2 1/5 is 1 13/20.

Carson walked her dog 1 13/20 more miles than Claire did.

Answer:

b = 90

c=80

d =100

Step-by-step explanation:

Given

See attachment

Required

Find b, c and d

First, we solve for b using:

b + 10 + b - 10 = 180 --- base angles of a parallelogram

Collect like terms

b + b =180+10-10

2b = 180

Solve for b

b = 180/2

b = 90

Then, we have:

d =b + 10

c = b - 10 --- opposite angles

So, we have:

d =90 + 10

d =100

c = 90 - 10

c=80

Emanuel has 745 pictures in his phone.His memory is getting full, so he starts deleting 20 pictures every day. Define each varia
BigorU [14]
Let f be the function with variable n, which gives the number of pictures left in the phone after deleting pictures for n-days.

So f(1) gives the number of photos left after 1 day of deleting photos

     f(2) gives the number of photos left after 2 days of deleting photos

     and so on.

f(1)=745-20
f(2)=745-20-20=745-20*2
f(3)=745-20-20-20=745-20*3

so clearly f(n)=745-20n

Answer:

the algebraic expression is f(n)=745-20n, 

where n is the n'th day of deleting photos, and f is the number of photos left after n days of deleting.
