8.40$ divided by 5 = 1.68$ each pound which makes 1.68$ the unit price per pound.

Now to check the answer 1.68$ times 5 gives us a total of 8.40$

Help I don’t understand at all

Answer:

$1)\ \ 4h^2-13h+6\\2)\ \ 7x^3y^2-x^2y+1\\3)\ \ -7n+2\\4)\ \ -8m+4$

Step-by-step explanation:

Simplify the expression by combining like terms. Remember, like terms have the same variable part, to simplify these terms, one performs operations between the coefficients. Please note that a variable with an exponent is not the same as a variable without the exponent. A term with no variable part is referred to as a constant, constants are like terms.

$2h^2-7h+2h^2-h+6+4h-9h$

$(2h^2+2h^2)+(-7h-h+4h-9h)+(6)$

$4h^2-13h+6$

Use a very similar method to solve this problem as used in the first. Please note that all of the rules mentioned in the first problem also apply to this problem; for that matter, the rules mentioned in the first problem generally apply to any pre-algebra problem.

$8x^3y^2-7x^2y+8x-4-x^3y^2+2x^2y+4x^2y-8x+5$

$(8x^3y^2-x^3y^2)+(-7x^2y+2x^2y+4x^2y)+(8x-8x)+(-4+5)$

$7x^3y^2-x^2y+1$

Use the same rules as applied in the first problem. Also, keep the distributive property in mind. In simple terms, the distributive property states the following ( $a(b+c)=(a)(b)+(a)(c)=ab+ac$ ). Also note, a term raised to an exponent is equal to the term times itself the number of times the exponent indicates. In the event that the term raised to an exponent is a constant, one can simplify it. Apply these properties here,

$-2(8n+1)-(5-9n)+3^2$

$-2(8n+1)-(5-9n)+(3*3)$

$-2(8n+1)-(5-9n)+9$

$(-2)(8n)+(-2)(1)+(-)(5)+(-)(-9n)+9$

$-16n-2-5+9n+9$

$(-16n+9n)+(-2-5+9)$

$-7n+2$

The same method used to solve problem (3) can be applied to this problem.

$\frac{1}{2}(10-8m+6m^2)-(3m^2+4m-7)-2^3$

$\frac{1}{2}(10-8m+6m^2)-(3m^2+4m-7)-(2)(2)(2)$

$(\frac{1}{2})(10)+(\frac{1}{2})(-8m)+(\frac{1}{2})(6m^2})+(-)(3m^2)+(-1)(4m)+(-1)(-7)-8$

$5-4m+3m^2-3m^2-4m+7-8$

$(-3m^2-3m^2)+(-4m-4m)+(5+7-8)$

$-8m+4$

John joined a video game club. Newer games cost $5 to rent and older games cost $3 to rent John has $30 to spend each month. How

LUCKY_DIMON [66]

Answer:

6 newer games and 10 older games

Step-by-step explanation:

To find how many newer games John can purchase, we divide $30 by $5. If we do the simple math in our head, we will get the answer of 6. Therefore, the amount of newer games John can purchase is 6. Now to find the amount of older games John can buy, we apply the same strategy. We take $30 and we divide it by $3. This will get us the answer of 10. Therefore, the amount of older games John can purchase is 10.

Hope this helps and if it does, don't be afraid to rate my answer as well as maybe give it a "Thanks"? (Or even better a "Brainliest"). And if it’s not correct, I am sorry for wasting your time and good luck finding the correct answer :)

Which equation represents the distributive property?

Arte-miy333 [17]

Answer:

Step-by-step explanation:

Distributive property is when you use the number on the outside of the parenthesis to multiply to the inside. So, 36+9=3(12+3), in order to solve it on the parenthesis side you would take 3 and multiply it by 12, giving you 36. Then, you would take 3 and multiply it to the other 3 which gives you 9.
