Write down the rules for multiplication and division of whole numbers

1 answer:

8 0

As division is the inverse of multiplication, the rules for division are the same as the rules for multiplication. So when multiplying and dividing positive and negative numbers remember this: If the signs are the same the answer is positive, if the signs are different the answer is negative.

Sunny_sXe [5.5K]

Answer:

See explanation

Step-by-step explanation:

Dinosaur Discovery show = 8 friends

Wild Weather show = 4 friends

Cost of Dinosaur Discovery show = $d

Cost of Wild Weather show = $w

At regular price:

Total cost of his friends' tickets = 8 * d + 4 * w

= 8d + 4w

At half price

Total cost of his friends' tickets =

8 * 1/2d + 4 * 1/2w

= 8/2d + 4/2w

= 4d + 2w

Total cost of his friends' tickets = 4d + 2w

ales tax is calculated as a percentage of the sales price. If sales tax is 7%, what is the sales tax on clothing that costs $150

Aneli [31]

Answer:

7% of 150= 10.5 :)

Step-by-step explanation:

150/x=100/7

(150/x)*x=(100/7)*x - we multiply both sides of the equation by x

150=14.2857142857*x - we divide both sides of the equation by (14.2857142857) to get x

150/14.2857142857=x

10.5=x

x=10.5

now we have:

7% of 150=10.5
