Stacie is playing a card game. There are 8 wild cards for every 40 standard cards. If there are 10 wild cards how many standard
docker41 [41]
If there are 10 wild cards there are 50 standard cards. 8 and 40 can both be divide by 4, which makes 2/10. This means that there are 2 wild cards for every 10 standard cards. If there are 50 wild cards, you simply multiply 2/10 by 5. This will give you 10/50. 10 wild cards in 50 standard cards.

In the figure above, if a:b:c = 3:4:1, what is the value of a?
Darina [25.2K]

Answer:

30

Step-by-step explanation:

The line is divided up into 3 parts, a part of 3, a part of 4, and a part of 1.  If we had those parts together we get 8 meaning if we divided the line into equal parts that also fit into a, b, and c there would be 8.  We can than divide the line into 8 parts which would be 10 each since a line is 180 degrees.  Since a is 3 than a gets 3 of those parts meaning a would be 30

I hope this helps and please don't hesitate to ask if there is anything still unclear!

Let f(x)= 7x-13.find f powered to the negative 1 power (x)
Reil [10]
Let f(x) be y so you have
y=7x-13
Reverse the signs of x and y so you have
x=7y-13
And then find the value of y
x+13=7y
(x+13)/7=y
And change y to f(x)-1
