Answer:
Set variables for the quantities we want to find.
Let x = number of apples
Let y = number of oranges
Next, we use these variables to write equations that describes the whole story.
Since the total price is $7.75 and each type of fruit has their own price, we can say
0.40x + 0.35y = 7.55
The other equation will represent the total number of fruits bought all together, as Mark mentioned. Once you have those equations, you solve the system using substitution and elimination methods to solve for the variables x and y.
Answer:
x=-11.9

Answer:
1
Step-by-step explanation:
multiply 9 and 2 which is 18 minus 15 which give u 3 divide by 3 and u get 1.
Answer:
Step-by-step explanation:
t is the number of hours
12.24+0.11t = 12.74-0.15t
0.11t + 0.15t = 12.74 - 12.24
0.26t = 0.5
t= 0.5/0.26
t= 1.92 hours
approx to 2 hours
