<span>Four times a number plus 3 is 11
</span>
$4 * n + 3 = 11$

$4n + 3 = 11 -3$

$4n = 8$

$4n/4=8 / 4$

$n = 2$

Hence solved

N - the number

4 · n + 3 = 11
4n + 3 = 11 |subtract 3 from both sides
4n = 8 |divide both sides by 4

n = 2

Luke buys a certain brand of cereal that costs $11 per box. Luke changes to a super-saving brand of the same size. The equation

Mkey [24]

Answer:

Part A:

Luke's original box of cereal costs $2 more than the super-saving brand.

y=9(1)

y=9

11-9=2

Part B:

y=9(6)

y=54

11x6=66

66-54=12

Luke saves $12 each month if he buys 6 boxes of the super-saving brand.

Complete the set of ordered pairs for the relation.

Nonamiya [84]

The set of ordered pairs are $(-2,18),(-1,20),(0,22),(1,24),(2,26)$

Step-by-step explanation:

Given that the relation $\{(x, y): y=2(x+11) \text { and } x \in(-2,-1,0,1,2)\}$

To find the set of ordered pairs, let us substitute the value for x in the relation $y=2(x+11)$

For $x=-2$ ,

$\begin{aligned}y &=2(-2+11) \\&=2(9) \\y &=18\end{aligned}$

The ordered pair is $(-2,18)$

For $x=-1$ ,

$\begin{aligned}y &=2(-1+11) \\&=2(10) \\y &=20\end{aligned}$

The ordered pair is $(-1,20)$

For $x=0$ ,

$\begin{aligned}y &=2(0+11) \\&=2(11) \\y &=22\end{aligned}$

The ordered pair is $(0,22)$

For $x=1$ ,

$\begin{aligned}y &=2(1+11) \\&=2(12) \\y &=24\end{aligned}$

The ordered pair is $(1,24)$

For $x=2$ ,

$\begin{aligned}y &=2(2+11) \\&=2(13) \\y &=26\end{aligned}$

The ordered pair is $(2,26)$

Thus, the set of ordered pairs is $(-2,18),(-1,20),(0,22),(1,24),(2,26)$
