The ages of four sisters are consecutive even integers. two times the age of the youngest sister exceeds the oldest sister's age by 30 years. the equation 2x − (x + 6) = 30 models the age, x, of the youngest sister. what is the age of the oldest sister?

Alright, lets get started.

The ages of all four sisters will be = x, x+2, x+4, x+6

As per given in question, two times of youngest sister age exceeds the oldest sister age by 30 means

Simplifying the equation

So this is the age of youngest sister.

So, age of oldest sister will be

Hene the age of oldest sister is 42 years.   :  Answer

Hope it will help :)

7 is the median   7.875 is the mean

step-by-step explanation:

3,4,5,6,8,11,13,13

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
