Answer:

1. x=6

2. x=2

Step-by-step explanation:

2:6

x:18

From 6 to 18, 6 was multiplied by 3. To keep the equality, we must multiply the other side by three as well. Therefore, x is equal to 2*3 which equals 6.

x=6.

5:7

(x+3):7

For this one, the second value did not change, so we know that x+3 has to equal 5. Therefore, x=2.

x=2

a store advertises that customers can take 25%off the original price and then take an extra 10%off is this 35% of? explain

kow [346]

No, it is not 35% off... Let me explain. Let's say the original price is $100 to make the math easy. When you take 25% off then take an additional 10% off, the 10% is off of the discounted price, so

100 x 25% = 100 x .25 = 25 dollar discount
New price = $75

Now 10% off of $75
10% x 75 = .10 x 75 = $7.50 discount
New price = 75 - 7.50 = $67.50

Now, if you just took 35% off of $100

100 x 35% = 100 x .35 = $35 discount
New Price = 100 - 35 = $65

Bottom line... when you take an "extra" percentage off, you are taking a percentage of a smaller number, so the discount is not as big.
