Let's simplify step-by-step.9(2x−1)−9x−18

Distribute:=(9)(2x)+(9)(−1)+−9x+−18=18x+−9+−9x+−18

Combine Like Terms:=18x+−9+−9x+−18=(18x+−9x)+(−9+−18)=9x+−27

Answer:

RC = 40

Step-by-step explanation:

Note that the circumcentre is equally distant from the triangle's 3 vertices.

That is : PC = RC = QC

Equate any pair and solve for x

Using RC = PC, then

5x - 15 = 3x + 7 ( subtract 3x from both sides )

2x - 15 = 7 ( add 15 to both sides )

2x = 22 ( divide both sides by 2 )

x = 11

Hence

RC = (5 × 11) - 15 = 55 - 15 = 40 units

On Monday you sent x number of text messages. On Tuesday you sent twice as many. On Wednesday you sent 12 more texts than you se

kykrilka [37]

Answer: Expression represents the number of text messages you sent on Tuesday = 2x

Expression represents the number of text messages you sent on Wednesday = 12+2x

Expression represents the number of text messages you sent on Thursday = x+6

Step-by-step explanation:

Given:

Number of text messages sent on Monday = x

On Tuesday, Number of text messages sent = 2 (Number of messages sent on Monday)

= 2 x

On Wednesday, Number of text messages sent = 12+ (Number of messages sent on Tuesday)

= 12 +2x

On Thursday, Number of text messages sent = $\dfrac12(2x+12)$

= x+6

Expression represents the number of text messages you sent on Tuesday = 2x

Expression represents the number of text messages you sent on Wednesday = 12+2x

Expression represents the number of text messages you sent on Thursday = x+6
