Answer:
Crafts books: 7
Cookbooks: 13
Step-by-step explanation:
Let x be the crafts book
Let y be the cookbooks
Solve for x:
- Plug x and y in: x + y = 20
- Re-write: y = x + 6
- Plug in x + 6 instead of y: x + x + 6 = 20
- Combine like terms: 2x + 6 = 20
- Subtract 6 from each side, so it now looks like this: 2x = 14
- Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 7
Solve for y:
- Re-use an equation from above: y = x + 6
- Plug in the value of x: y = 7 + 6
- 7 + 6 = 13
- So, y = 13
I hope this helps!
Answer:

Step-by-step explanation:
The general direct variation equation is
y = kx
Plug in x = 4 and y = 6 and solve for k.
6 = k * 4
4k = 6
k = 6/4 = 3/2

Here we know that at 3:17 pm you started to bake the cake. The total revolution the minute hand on the clock makes is:

We know that:

Solving for x:

So it takes 70 minutes after you put the cake in the oven. But:

Adding this to the initial time:

Finally, the cake is done at 4:27 pm, option C.
