Answer:

k=3

Step-by-step explanation:

4.5+1.5k=18-3k

Subtract 4.5 to both sides

15k=13.5-3k

Add 3k to both sides

4.5k=13.5

Divide both sides by 4.5 to get k alone

\frac{4.5k}{4.5} =\frac{13.5}{4.5}

k=3

Hope this helps can pls do mark me brainliest:)

Answer:

k = 3

Step-by-step explanation:

Given

4.5 + 1.5k = 18 - 3k ( add 3k to both sides )

4.5 + 4.5k = 18 ( subtract 4.5 from both sides )

4.5k = 13.5 ( divide both sides by 4.5 )

k = 3

In a poll, 44% of the voters say they plan to reelect the mayor. The poll has a margin of error of ±3 percentage points. Use a m
Amanda [17]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Percentage of voters who plan to re-elect mayor = 44%

Margin of Error in measurement = ±3 % points

The absolute value inequality to find the lowest and greatest percent of points :

X = mid value

44% = estimated percentage

≤3 = error margin

Hence,

|mid value - estimate| ≤ error margin

|x−44|≤3

Hence,

-3 ≤ x - 44 ≤ +3

-3 + 44 ≤ x ≤ 3 + 44

41 ≤ x ≤ 47

Hence,

Least percentage point = 41

Greatesr percentage point = 47

<span><span>Corresponding angles are congruent (same measure)So in the figure above, the angle P=P',  Q=Q',  and R=R'.</span><span>Corresponding sides are all in the same proportionAbove, PQ is twice the length of P'Q'. Therefore, the other pairs of sides are also in that proportion. PR is twice P'R' and RQ is twice R'Q'.  
so the value of x :
x / 110 = 21.6 / 72
solve for x
x = 33</span></span>
