40 yards I think please tell me if im wrong!
Answer: 7/6 or 1 and 1/6
Step-by-step explanation:
2 1
+
3 2
you have to make them have the same denominators(the number on the bottom of a fraction)
2/3--> 4/6
1/2---> 3/6
4/6+3/6=7/6 or 1 and 1/6
Answer:
Step-by-step explanation:
Let's identify what we are looking for in terms of variables. Sandwiches are s and coffee is c. Casey buys 3 sandwiches, which is represented then by 3s, and 5 cups of coffee, which is represented by 5c. Those all put together on one bill comes to 26. So Casey's equation for his purchases is 3s + 5c = 26. Eric buys 4 sandwiches, 4s, and 2 cups of coffee, 2c, and his total purchase was 23. Eric's equation for his purchases then is 4s + 2c = 23. In order to solve for c, the cost of a cup of coffee, we need to multiply both of those bolded equations by some factor to eliminate the s's. The coefficients on the s terms are 4 and 3. 4 and 3 both go into 12 evenly, so we will multiply the first bolded equation by 4 and the second one by -3 so the s terms cancel out. 4[3s + 5c = 26] means that 12s + 20c = 104. Multiplying the second bolded equation by -3: -3[4s + 2c = 23] means that -12s - 6c = -69. The s terms cancel because 12s - 12s = 0s. We are left with a system of equations that just contain one unknown now, which is c, what we are looking to solve for. 20c = 104 and -6c = -69. Adding those together by the method of elimination (which is what we've been doing all this time), 14c = 35. That means that c = 2.5 and a cup of coffee is $2.50. There you go!
ANSWER
The rule is given by the relation,

EXPLANATION
We need to check and see if there is a constant difference between the y-values.

We can see that, there is a constant difference of 2.
This means that the table represents a linear relationship.
Let the rule be of the form,

Then the points in the table should satisfy the above rule.
So let us plug in

This implies that,



Our rule now becomes,

We again plug in another point say, (-1,-1) in to equation (1) to get,

we solve for m now to obtain,



We now substitute back in to equation (1) to get
Well the cost of the apples can be found by dividing the price by the amount bought. ($5/4 or $10/8 = $1.25/lb). If you want to find the amount for 6 pounds just multiply it by the individual cost (6x$1.25= $7.50)
