Answer:
x=1, y=8
Step-by-step explanation:
Plug y=8x into y=10x-4.
8x=10x-4
Subtract 10x from each side.
-2x=-2
Divide each side by -2.
x=1
Plug x=1 into y=8x.
y=8(1)
y=8
Answer:
False, it would actually be 106 beads. If this was a multiplication problem, that would also be false, because 6 times 100 is 600, not 350.
But let's attempt to make this statement true.
<u>First/Last step:</u><em> Find the missing beads.</em>
The missing beads are 144.
Why?
Because you must add 144 to reach 250, there is no other way but to multiply. In this case, because the key word is, "In all" we are adding.
The original price is 100% of the price. If the price is marked 60% off, then you pay 40% of the original price.
An item costs x dollars.
With the 60% off discount, it now costs 40% of x, or 0.4x.
Now you apply a 30% discount.
For the second discount, consider the price 0.4x to be the new original price. If the price is now discounted 30%, you will pay 70% of the new original price.
Start with 0.4x.
Now calculate 70% of 0.4x.
70% of 0.4x = 0.70 * 0.4x = 0.28x
After applying the 60% discount and the 30% discount, the item that originally cost x now costs 0.28x. 0.28x is the same as 28% of x. The amount you pay is 28% of the original price.
Answer: 28%
It would be 23 I’m pretty sure:)
since you have 11 cards and need to know how many red and black
r+b needs to equal 11
since r+b=11 isn't shown in any answer then none of them are correct, so none of the above
