Remember, "mean" means the average of the numbers.
In order to find an average, add all the numbers together, then divide by the amount of numbers.
So:
1+5+7+9+11+16+18+20+30+35=153

Since there are 10 numbers in the sequence, divide by 10.
153/10=15.3

Solve the equation for x by combining like terms first. <br> 3x-10+5x=2x-13
diamong [38]

Step-by-step explanation:

\tt{3x - 10 + 5x = 2x - 13}

Combine like terms on left hand side. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.

⟼ \tt{3x + 5x  - 10 = 2x - 13}

⟼ \tt{8x - 10 = 2x - 13}

Transpose 2x to left hand side and change it's sign.

Similarly , Transpose 10 to right hand side and change it's sign.

⟼ \tt{8x - 2x =  - 13 + 10}

⟼ \tt{6x =  - 3}

Divide both sides by 6

⟼ \tt{ \frac{6x}{6}  =  -  \frac{3}{6}}

⟼ \tt{x =  -  \frac{1}{2}}

\red{ \boxed{ \boxed{ \tt{Our \: final \: answer :  \boxed{ \underline{ \tt {x =  -  \frac{1}{2}}}}}}} }

Hope I helped ! ♡

Have a wonderful day / night ! ㋡

Decimals and fractions are alike because all decimals are fractions and all fractions are decimals. As an example: 1/2, which is one-half, is the same as 0.5.
