Answer: 27/14

Step-by-step explanation: It's important to understand that dividing by a fraction means the same thing as multiplying by the reciprocal of that fraction. In other words, we can simply change the division symbol to multiplication and flip the second fraction.

So we can rewrite this problem as 3/7 · 9/2.

When multiplying two fractions together, we multiply across the numerators and we also multiply across the denominators.

So 3/7 · 9/2 is 27/14.

An article was marked #80.00 During clearance sales a costumer paid #60.00 for it. What was the discount percentage​
Alik [6]

Subtract to find the amount of the discount:

80.00 - 60.00 = 20.00

Divide the amount of discount by original price:

20.00 / 80.00 = 0.25

Multiply by 100 to get percent:

0.25 x 100 = 25%

Answer: 25%

Danielle wants to buy a video game. At the local Big Box store, it costs $49.95. Danielle has a coupon for 10% off at the store,
KATRIN_1 [288]
Here are the answers to the questions above. Given the problem, let us solve first for the cost of each store. At a local store, it costs $49.95. Since she has a 10% off discount, the amount that she will be paying is $44.955. Since, there is a 6.5% tax, the total amount she will be paying is $48.20. Now, for the online store, it costs $44.95 plus a shipping charge of $4.00 so the total would be $48.95. Given these results, it would be cheaper if she buys in the local store. Hope this helps.

I’m not sure about this please help
castortr0y [4]

Answer:

3

Step-by-step explanation:

Evaluate x/4 + 6 (x - 12) where x = 12:

x/4 + 6 (x - 12) = 12/4 + 6 (12 - 12)

Hint: | Reduce 12/4 to lowest terms. Start by finding the GCD of 12 and 4.

The gcd of 12 and 4 is 4, so 12/4 = (4×3)/(4×1) = 4/4×3 = 3:

3 + 6 (12 - 12)

Hint: | Look for the difference of two identical terms.

12 - 12 = 0:

6×0 + 3

Hint: | Any number times zero is zero.

0×6 = 0:

0 + 3

Hint: | Simplify the expression.

Write 3 + 0 as 3:
