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

What is the measure of angle 4??? please help asap!!!
ArbitrLikvidat [17]
<h3>Answer: 80 degrees</h3>

===========================================================

Explanation:

Angle 3 and the 100 degree angle are corresponding angles. They are both in the southeast quadrant of their four-corner angle configuration. Assuming the lines that look horizontal are parallel, this would mean angle 3 is 100 degrees. Recall that corresponding angles are congruent when we have parallel lines.

Once we know that angle 3 = 100, we will use this to find angle 4.

Angles 3 and 4 add to 180. They form a straight angle or straight line.

(angle3)+(angle4) = 180

(100) + (angle4) = 180

angle4 = 180-100

angle4 = 80 degrees

ANSWER ASAP PLEASE FOR BRAINLIEST
PSYCHO15rus [73]

Answer:

<h2><em><u>11.2 - B to C</u></em></h2><h2><em><u>12 - B to A</u></em></h2><h2><em><u>8.8 - A to C</u></em></h2>

You have to multiply all the sides by 4.

B to C = 2.8*4

2.8 * 4 = 11.2

B to A = 3*4

3*4 = 12

A to C = 2.2*4

2.2*4 = 8.8

Hope this helped!
