Eight eagle stamps and two raccoon stamps cost $2.80. Three eagle stamps and four raccoon stamps cost $2.35. Find the cost of ea
nikklg [1K]

Answer:

Cost of each eagle stamp = $0.25

Cost of each racoon stamp = $0.4

Step-by-step explanation:

Given:

Cost of 8 eagle stamp and 2 racoon stamp = $2.80

Cost of 3 eagle stamp and 4 racoon stamp = $2.35

Find:

Cost of each stamp

Computation:

Assume;

Cost of each eagle stamp = e

Cost of each racoon stamp = r

So,

8e + 2r = 2.80........... Eq 1

3e + 4r = 2.35 ........... Eq 2

Eq 1 x 2

16e + 4r = 5.6 .........Eq3

Eq 3 - Eq 2

13e = 3.25

e = 0.25

Cost of each eagle stamp = $0.25

8e + 2r = 2.80

8(0.25) + 2r = 2.80

2 + 2r = 2.80

r = 0.4

Cost of each racoon stamp = $0.4

Which fraction is greater? how do you know? a) 2/3 , 2/5​
rusak2 [61]

Answer:

2/3 is greater

Step-by-step explanation:

Two fractions can only be compared if their denominators are equal. In the given problem they are different, so first we make them equal.

\frac{2}{3}  =  \frac{2 \times 5}{3 \times 5}  =  \frac{10}{15}  \\  \\  \frac{2}{5}  =  \frac{2 \times 3}{5 \times 3}  =  \frac{6}{15} \\  \\   \because \: \frac{10}{15} > \frac{6}{15} \\  \\  \purple{ \boxed{ \bold{ \therefore \: \frac{2}{3}   > \frac{2}{5}  }}}
