Answer:

Step-by-step explanation:

5 - 3(x - 4) use the distributive property: a(b + c) = ab + ac

= 5 + (-3)(x) + (-3)(-4)

= 5 - 3x + 12 combine like terms

= -3x + (5 + 12)

= -3x + 17

Describe the relationship between n and 4 that will make the value of the expression 6 x n/4 greater than 6.

KatRina [158]

Answer:

n is greater than 4

Step-by-step explanation:

We have to find the relation between n and 4 for which $(6\times \frac{n}{4})$ is greater 6.

Converting this verbal expression into algebraic expression,

$(6\times \frac{n}{4})>6$

$(6\times \frac{n}{6\times 4})>\frac{6}{6}$

$\frac{n}{4}>1$

$\frac{n}{4}\times 4>1\times 4$

n > 4

Therefore, relation between n and 4 is "n is greater than 4".

Help me ASAP!!!!!!!!

larisa [96]

Step-by-step explanation:

a) The rule is multiply the previous term by 6 then add 13. So if the 1st term is n0 = -2, then the next term n1 is

n1 = 6n0 + 13

= 6(-2) + 13

= 1

n2 = 6n1 + 13

= 6(1) + 13

= 19

So the sequence goes like

-2, 1, 19

b) Now the sequence is reversed so let's write the terms as follows:

19, 1, -2

The new rule now is subtract 13 then divide by 6. You can check this as follows:

n0 = 19

n1 = (n0 - 13)/6

= (19 - 13)/6

= 1

n2 = (n1 - 13)/6

= (1 - 13)/6

= -2

Pam ate 9 nuts in 6 minutes . if she continued eating at the same rate,how many would she eat in:

Lemur [1.5K]

Answer:

18 nuts in 12 minutes, 13.5 nuts in 4 minutes and 90 nuts in one hour

Step-by-step explanation:

12 min :

12/6 = 2

2 x 9 = 18 nuts in 12 minuts

4 min:

6/4 = 1.5

1.5 x 9 = 13.5 nuts in 4 minutes

(round to 13 if whole nuts only)

1 hour:

1 hour = 60 mins

60/6 = 10

9 x 10 = 90 nuts in one hour
