Answer:
Average weight of the bags of potatoes is 3.8 pounds.
Step-by-step explanation:
Given:
Weight of the first bag, 
pounds.
Weight of the second bag is 0.4 pounds less than twice the weight of first bag. This means,
Weight of the third bag is 0.6 pounds more than that of the first bag. This means,
Weight of the fourth bag is 0.3 pounds less than that of the second bag. This means,
Therefore, the average weight of the bags of potatoes is given as the sum of all the weights and then divide the sum by 4. Therefore,
Therefore, average weight of the bags of potatoes is 3.8 pounds.
I think it is B, since x goes right 4.5 times and y goes up 3 times.
The series will be:
Hence, Option A is the right answer
Step-by-step explanation:
The series can be fount out by putting the values of i in the expression written with the summation
The expression is:
while i = 1 to 25
Putting i = 1
Putting i = 2
Putting i = 3
....
Putting i = 25
The series will be:
Hence, Option A is the right answer

Answer:
x is smaller than 10in so x<5
Step-by-step explanation:
X (a + 2) = 7
First let's multiply out the brackets on the left side of the equation.
x (a + 2) --> Multiply everything inside the brackets by x.
xa + 2x = 7
Now, both elements of the left-hand side of the equation contain x, so we can divide both sides of the equation by x.
xa + 2x = 7
a + 2 = 7/x
To find a now, just subtract 2 from both sides.
a = 7/x - 2
