Answer:
3,5,7
Step-by-step explanation:
odd numbers is a multiple of three, at least one of them can't be prime
hope this helps there is 1 of them
Gonna do a little subbing here...
for 40 pgs of express proof reading....3 bucks per pg...c = 3
40(3) - 0.05(40(3)) = T
120 - 0.05(120) = T.....120 - 6 = T.....114 = T
so express proofreading cost 114
for 40 pgs of basic proof reading....c = 3.95
40(3.95) - 0.05(40(3.95) = T
158 - 0.05(158) = T....158 - 7.9 = T.....150.10
so basic proof reading costs 150.10
for 40 pgs of extended proof reading....c = 5
40(5) - 0.05(40(5) = T
200 - 0.05(200) = T....200 - 10 = 190
so extended proof reading is 190
no need to go further....the extended proof reading is gonna be ur answer...the best quality of editing that keeps it at 190
Answer:
66
Step-by-step explanation:
Answer:
OPTION A
OPTION B
OPTION D
Step-by-step explanation:
Given that a bag of apples cost 'a' dollars.
A bag of oranges cost 'a + 2' dollars.
Therefore, one bag each of apples and oranges should cost: a + a + 2 dollars.
Since, Dorie buys 5 bags of apples and Oranges, it would have costed her:
5(a + a + 2)
= 5(2a + 2)
= 10a + 10
Hence, OPTION A, B and D are the correct answers.
For two ratios to form a proportion they have to be equal.
To see if two ratios are equal we express them in their simplest form.
In this case we notice that in the first ratio both numbers are multiples of five, then:
In the second case we notice that both numbers are multiples of 2, then:
Since both ratios can be simplified to the same final ratio, they form a proportion.
