Ryan bought 6 apples and 9 peaches for a total of $7.86. Madi bought 4 apples and 5 peaches for $4.82. How much are apples and p
Scilla [17]
Let, x = The cost of an apple
y = The cost of a peach

6x + 9y = 7.86 - - - - - - - - 1
4x + 5y = 4.82 - - - - - - - - 2

From equation 2,
4x =4.82 - 5y
x= (4.82 - 5y) ÷ 4 - - - - - - - 3

Substitute 3 into 1,
6x + 9y = 7.86
6 [(4.82 - 5y) ÷ 4] + 9y = 7.86
(28.92 - 30 y) ÷4 + 9y = 7.86
28.92 - 30y + 36y = 31.44
6y=2.52
y= 0.42

Substitute y = 0.42 into 2
4x + 5y= 4.82
4x + 5 (0.42) = 4.82
4x + 2.1 = 4.82
4x= 2.72
x= 0.68.

Thus, an apple costs $ 0.68 and a peach costs $ 0.42.

Abby rode the Metro bus 4 miles farther than James rode. The sum of their distances traveled is 28 miles. How far did James ride
ohaa [14]
A. define the variables : a = abby's miles, j = james' miles

b. a = j + 4......j = a - 4

c. a + j = 28
    a = j + 4
    
 d. (j + 4) + j = 28
      2j + 4 = 28
      2j = 28 - 4
      2j = 24
       j = 24/2
       j = 12
  
       a = j + 4
       a = 12 + 4
       a = 16

e. check..
     a + j = 28
     16 + 12 = 28
      28 = 28 (correct)

solution is : abby's miles (a) = 16
                   james' miles (j) = 12
