Zoe claims that the expression - 4(m-2) is equivalent to - 4m-2. Which statement identifies and corrects the error in Zoe's work?

A.) A Zoe did not subtract 2 from – 4m; the equivalent expression is - 6m.
B.)Zoe did not subtract 2 from – 4; the equivalent expression is – 4m-6.
C.)Zoe did not find the product of - 4 and -2; the equivalent expression is -4m+8.
D.)Zoe did not keep the parentheses around -2; the equivalent expression is – 4m(-2).

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.

hope to and hope that my answer is brainliest.(follow me )

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

i hope this is what you were looking for.

see attached graph

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
