Given, the ratio of blocks A, B, C,D are in the ratio 4:7:3:1
Let us consider the common ratio to be ‘x’.
So, toy blocks with alphabet A is 4x and
toy blocks with alphabet B is 7x and
toy blocks with alphabet C is 3x and
toy blocks with alphabet D is x
Again, the number of ‘A’ blocks is 50 more than the number of ‘C’ blocks.
As no. of ‘A’ and ‘C’ blocks are 4x and 3x respectively.
So,
4x=50 + 3x
x=50
Thus, the number of ‘B’ blocks is 7x = 7(50) = 350
350 is the required number.
Answer:
Yes. This equation defines y as function of x.
Step-by-step explanation:
Step 1:
Solve the equation for y (this puts the equations in terms of y)
2x+y=8 becomes
y = 2x - 8
This is a linear equation, which is a funtion.
*Another way to solve this is to look at the graph. Graphing this equation gives us a line. Use the vertical line test to see if it's a function.
To pass the vertical line test (VLT), there can only be one y value to each x value along the graph. If it passes the VLT, the equation is a function.
If it fails the VRT, the equation is not a function.
