Find the value of x.

ruslelena [56]

Answer:

Step-by-step explanation:

(10 - x ) / x = 3/2 Cross Multiply

2*(10 - x) = 3x Remove the brackets

20 - 2x = 3x Add 2x to both sides

20 = 3x + 2x

5x = 20 Divide both sides by 5

x = 20/5

x = 4

Alex

Answer: 12 miles

Step-by-step explanation:

Hi, to answer this question we have to write a growth equation.

Total miles = 8 (1 +0.05)^9 = 12.41 =12 miles

Where 8 is the initial miles she run, since is increasing each week by 5% we have to multiply it by 1+ percent increase rate in decimal form (1+0.05) to 9th power (number of weeks)

She will run 12 miles in 9 weeks.

kupik [55]

Answer:

Solution given;

<M=5x+10

<R=55

<M+<R=90°

5x+10+55=90°[is a required equation]

now solving it

5x=90-65

5x=25

x=25/5

x=5is your answer.
