44 markers cost $7.04 Which equation would help determine the cost of 7 markers?

(7.04/44)*7

7*(7.04/44)

Step-by-step explanation:

you have to find the cost of each individual marker:

$7.04/44= .16 (Checked it on a calculator)

then you multiply .16 by 7 because each marker costs 16 cence and you need to find the total cost of 7 markers so your equation should look like:

#1 way to write it: (7.04/44)*7

#2 way to write it: 7*(7.04/44)

$ 1.12

Step-by-step explanation:

markers       :         cost

   44             :         7.04

   7              :           x

x is used to find the cost of 7 markers

now cross multiply:

44x = 7*7.04

44x = 49.28

x = 49.28 / 44

x = $ 1.12

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?
