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:
y+(y-2)+(y-4)=0
y+y-2+y+y-4=0
4y-6=0
4y=6
y=6/4
y=3/2
Step-by-step explanation:
Answer:
it is y/5
Step-by-step explanation:
it says to transform it into an expression.
As its one significant figure you are looking at the first number and the second number. If the second number is greater than 5 then you round the first number up and vice versa. In this case there is an eight, which is bigger than 5 obviously so you round the first number to get 40000.
No those two fractions are not proportional.
25 times 20 = 500
70 times 8 = 560
500 and 560 are not equal so therefore the fractions are not proportional. Hope this helps!
