Answer:
Step-by-step explanation:
Remark
The last digit is 1 3 5 7 9 because the last digit is odd.
The first digit must be a 3 because the number is between 300 and 350
Let the first digit = x
Let the second digit = y
Let the third digit = z
x + y = z
x + y + z = 14 Substitute z for x + y
z + z = 14 Combine
2z = 14 Divide by 2
2z/2 = 14/2
z = 7
The first digit is 3 and the third digit = 7
The middle digit is 3 less than the last digit.
y = 7 - 3 = 4
Answer
347
The surface area is 540 square feet because you can find the area of each face (lw) and that is 90. 90*6=540
Answer:
The number of days in which the amount in warehouse #2 is 1.2 greater than warehouse #1 is 6 days.
Step-by-step explanation:
Let
x: number of days
y: amount of potatoes
We can express the amount of potatoes in each warehouse using linear equations:
Warehouse #1: 
Warehouse #2: 
We need to find the value of x when 
Substituting the expressions for y1 and y2 in :
Applying distributive law:
Solving the equation by subtracting 108x and 180 on both sides:
Now we divide by 12 on both sides:
Therefore, the number of days in which the amount in warehouse #2 is 1.2 greater than warehouse #1 is 6 days.
D = discount on third shirt
c = total cost
Sales tax of 7.1% equates to 1.071
c = (Cost of 1st Shirt + Cost of 2nd Shirt + Cost of Third Shirt) * Sales Tax
c = (49.96 + 49.96 + (49.96 - d)) * 1.071
Since you didn't specify the discount on the third shirt, this is the best I can do for you.
The mean of the cost of the shirts would be c/3
If the ratio you presented is 5 dogs:6 cats you would divide 35 by 6 and get a number (I don't have a calculator on me), then take that number and multiply it by 5 to get the number of dogs. If the ratio is 5 cats:6 dogs then divide 35 cats by 5 to get 7, then multiply 6 by 7 to get 42 dogs.
