Is the equation 8x12x5 =- 8x(12x5) an associative property or distributive property equation?

Answers

Answer 1

Answer: well it is distributive but you don't but the multiplication sign by the 8 with the parenthesis so it would be 8(12*5) and then you do 8*12 which is 96 and then 8*5 which is 40 and then add 96+40

Answer 2

Answer: This is an Associative property equation

Mr. Conrad's pecan pie recipe calls for 1 3/4 cups of pecans. He plans to make 6 pies for his family reunion. How many cups of pecans will Mr. Conrad need

Answers

According to my calculations the answer is 19.5 or 19.50 you can pick either one but your teacher will probably want the first.

$1 (3)/(4)$ x 6 (or $(6)/(1)$

Change 1 3/4 to an improper fraction = $(7)/(4)$

$(7)/(4)$ x $(6)/(1)$ = $(42)/(4)$ = 10 $(2)/(4)$ cups
Reduce the answer and get 10 $(1)/(2)$ cups

The formula V=lwh is used to calculate the volume of a rectangular prism. What is the equation solved for h?A)Vlw=h
B)lw/v=h
C)V/lw=h
D)Vh=lw
10 points!!! Please help!!

Answers

(h is multiplied with l and w. The opposite of multiplication is division. divide lw from each side)

$V=lwh$

$(V)/(lw) = (lwh)/(lw)$

$(V)/(lw) =h$

The answer is C) V/lw = h

You have said that V = l w h

Divide each side by ' l w ' : V / l w = h

Ron bought 8 pencils and 2 erasers for $1.66. Sarah bought 12 pencils and 5 erasers for $3.19. What is the cost for 1 pencil and 1 eraser?

Answers

p=price of 1 pencil
e=price of 1 eraser

1.66=8p+2e
divide by 2 for simplification
0.83=4p+e

3.19=12p+5e

0.83=4p+e
multiply by -5 and add to obht eration

-4.15=-20p-5e
3.19=12p+5e +
-0.96=-8p

divide by -8
0.12=p
sub back

0.83=4p+e
0.83=4(0.12)+e
0.83=0.48+e
minus 0.48 both sides
0.35=e

1e+1p=0.12+0.35=0.47

cosst is $0.47
