Ramesh buys 10 containers of juice from an online shop and 18 containers of the same juice from another shop.If the capacity of
frutty [35]

Answer:

Rs. 4200

Step-by-step explanation:

If Ramesh buys 10 containers, each for 150, we can add 150 + 150 + 150 + 150 + 150 + 150 + 150 + 150 + 150 + 150 (there's ten 150's).

Or, instead of doing a lot of adding, we can use multiplication (repetitive addition is the same thing as multiplication; but instead of adding over and over again, we multiply by how many "groups" of the number that we have. For example, let's say that our group size is 150. If we buy 10 containers, we have bought 10 x 150 containers.)

So, we can use 10 x 150 for the first ten containers. However, we can solve this problem in a slightly more practical way. We can first add the total amount of containers (the total amount of "groups" of 150), 10 + 18 = 28.


So, to solve this equation, we are finding 28 x 150.

150 x 28 = 4200

(150 = size of "group"/price of container)

(28 = amount of "groups"/containers)

So, the total amount of money spent by Ramesh is Rs. 4200

Alex787 [66]

This would be displayed as 11 - 5k

This cannot be solved, however, without knowing the value of k, or at least what the expression is equal to.

What is the slope-intercept form for a line that passes through (4,3) and is parallel to x=0
nikitadnepr [17]

Answer:

x=4

Step-by-step explanation:

x=0 is an undefined slope(straight line vertically)

We need the line to pass through the point (4,3)

So, we just take the x coordinate from the equation and make it also have an undefined slope.

x = 4
