7. The difference of Grandma Annie's age and twice Carl's is 22. Gran
OlgaM077 [116]
<h2>Systems of Equations Word Problems</h2>

To solve these questions, we can translate key words into operations:

  • <em>Difference</em> = subtract
  • <em>Twice</em> = double
  • <em>Less than</em> = subtract

<h2>Solving the Question</h2>

We're given:

  • Difference of Annie's age and twice Carl's age is 22
  • Annie's age is 13 less than 3 times Carl's age

There are two variables given two us: Annie's age and Carl's age.

  • Let Annie's age be equal to <em>x.</em>
  • Let Carl's age be equal to <em>y</em>.

Translate the given information into two equations:

  • Difference of Annie's age and twice Carl's age is 22
    ⇒ x-2y=22
  • Annie's age is 13 less than 3 times Carl's age
    ⇒ x=3y-13

Now, we can substitute the fist equation into the second one to solve for <em>y</em>:

(3y-13)-2y=22\\3y-13-2y=22\\y-13=22\\y=35

Now, substitute <em>y</em> back into the second equation to solve for <em>x</em>:

x=3y-13\\x=3(35)-13\\x=105-13\\x=92

<h2>Answer</h2>

Therefore, Grandma Annie is 92 years old.

What is an equation of the line that passes through the points (-3,-1) and
NARA [144]

The equation of line that passes through the points (-3,-1) and

(-6,3) is:

y=-\frac{4}{3}x-5

Step-by-step explanation:

Given points are:

(-3,-1) =(x1,y1)

(-6,3)=(x2,y2)

The slope-intercept form of equation of line is:

y=mx+b

We have to find the slope first

m=\frac{y_2-y_1}{x_2-x_1}\\=\frac{3-(-1)}{-6-(-3)}\\=\frac{3+1}{-6+3}\\=\frac{4}{-3}

Putting the value of slope in the slope intercept form

y=-\frac{4}{3}x+b

To find the value of b, putting the point (-3,-1) in the equation

-1=-\frac{4}{3}(-3)+b\\-1= 4+b\\b=-4-1\\b=-5

Putting the values of b and m

y=-\frac{4}{3}x-5

The equation of line that passes through the points (-3,-1) and

(-6,3) is:

y=-\frac{4}{3}x-5

Keywords: Equation of line, slope intercept form
