Create your own system of 2 equations word problem. Answer it with full step by step explanation. Help and thank you. ​
mr_godi [17]

Answer:

<h2>30</h2>

Step-by-step explanation:

<h3>to understand the steps</h3><h3>you need to know about:</h3>
  • system of linear equation
  • word problems
  • PEMDAS

first step

let's create the equation word problem

<h3>my mother's current age is four times the sum of the ages of my two sisters. After 5 years, my mother's age will be double the sum of the ages of my two sisters. What is the current age of my mother? (imaginary problem)</h3>

let's solve

let my mother's and sister's age be x and y respectively

according to the first condition,x=4y....(I)

according to the 2nd condition,x+5=2(y+5×2).....(ii)

so the system of linear equations is

x=4y

x+5=2(y+5×2)

gets from the second equation

x+5=2(y+10)

x+5=2y+20

4y+5=2y+20 (as x=4y)

2y=15

y=7.5

so the age of mother is

x=4.(7.5)

x=30

Answer:

B:  (x - 4)² = 44

Step-by-step explanation:

Start with x^2 - 8x - 10  =  18.

Simplify the constants by adding 10 to both sides:  x^2 - 8x - 10 + 10 = 18 + 10.

Then x^2 - 8x = 28.

Now identify the coefficient of x.  It is -8.  

Take half of this, obtaining -4.

Square this result, obtaining 16.

Add 16, and then subtract 16, to x^2 - 8x:

x^2 - 8x + 16 - 16 = 28.

Add 16 to both sides:

x^2 - 8x + 16 = 28 + 16 = 44

Rewrite x^2 - 8x + 16 as (x - 4)², so that we have:

(x - 4)² = 44.  This is in the form (x - p)² = 44, and matches Answer B.

Note:  Please use " ^ " to indicate exponentiation:  (x - 4)^2 = 44
