What are additive and multiplicative inverses?
A number's additive inverse is a number that is added to it until the result is zero.
A number multiplied by another such that the result is 1 is the multiplicative inverse of that number.
We know if 'a' is a number then the opposite of 'a' is '- a'.
Given, Liliana spells a word incorrectly and loses 18 points.
Looses 18 points is '- 18'.
Marcus spells a word correctly and has the opposite score which is + 18.
As opposite of - 18 is + 18.

Answer: Two equivalent forms are :
Step-by-step explanation:
Since we have given that
62.5%
We have to write in equivalent forms:
1) First equivalent form is given by
2) Second equivalent form is given by
Percents are parts of 100, so write 62.5 as a fraction over 100:
62.5/100
Divide the numerator and denominator by 12.5:
62.5 / 12.5 = 5
100 / 12.5 = 8
5/8
This is one form.
62.5 / 100 = 0.625
This is another form.

b. buying a membership for $35 and then getting the item at a 15% discount
c. buying the item online at a 10% discount and paying $4 extra for shipping
Answers
Answer:
Buying the item online at a 10% discount and paying $4 extra for shipping
Step-by-step explanation:
Ray wants to buy an item worth 500$ in the most cost-effective way. Let's study each of the 3 cases and see with option is the best.
In the first option, he'll buy the item at list price with a coupon for $10 off. So he'll buy it at 500-10 =$490.
In the second option, he'll buy a membership for $35 and then get the item at a 15% discount. With a 15% discount, the price of the item will be 500 - (500*0.15) = 500 - 75 = $425. And with the membership price, he'll pay a total of 425 + 35 = $460.
The third option is to buy the item online at a 10% discount and pay $4 for the shipping. At 10% discount, the price of the item will be 500 - (500*0.1) = 500 - 50 = $450. And with cost of the shipping, he'll pay a total of 450+4 = $454.
So if he chooses the first option, he'll pay $490. With the second, he'll pay $460. And finally with the third, he'll pay $454.
So the third option is the most cost-effective, buying the item at $454.
Hope this helps! :)

For the given expression v+9/3=8, the value of v is 5.
To find the value of v in the equation v + 9/3 = 8, we can follow these steps:
Simplify the equation.
In this case, we can simplify the equation by dividing 9 by 3, which equals 3.
The equation becomes v + 3 = 8.
Isolate the variable v.
To isolate v, we need to get rid of the 3 on the left side of the equation. We can do this by subtracting 3 from both sides of the equation.
v + 3 - 3 = 8 - 3.
Therefore, in the equation v + 9/3 = 8, the value of v is 5.

The volume ofthe rectangular prism is: 1.39 ft³
The volume ofone of the small cubes is: 0.0046 ft³
What is the Volume of a Rectangular Prism?
Volume of rectangular prism = length × width × height
Given the following:
Length = 1 ft
Width = 5/6 ft
Height = 1⅔ ft
Volume of the rectangular prism = 1 × 5/6 × 1⅔ = 1 × 5/6 × 5/3
Volume of the rectangular prism = 25/18 = 1 7/18 ft = 1.39 ft³
Length of the edge of 1 cube = 1/6 ft
Volume of the 1 cube = (1/6)³ = 1/216 = 0.0046 ft³

Answer:
1. 1.3778 2. 0.0089
Step-by-step explanation:
to find the volume of the whole rectangle prism you would have to do the volume formula since it is a 3d shape. VOLUME FORMULA, LxWxH.
so 1x0.83x1.66= 1.3778
you can always convert the fraction into decimal to help you calculate the problem.
i don't know if this is correct but i give it a try, so if the whole volume of the triangle is 1.3378 than you can divide that by the the number of small cubes it has inside.
it is 5 by 10 so there are 150 cubes in total.
1.3378 divided by 150=0.0089
im confident about the 1st but not so much with the second
