By the knowledge and application of <em>algebraic</em> definitions and theorems, we find that the expression - 10 · x + 1 + 7 · x = 37 has a solution of x = 12. (Correct choice: C)

<h3>How to solve an algebraic equation</h3>

In this question we have an equation that can be solved by <em>algebraic</em> definitions and theorems, whose objective consists in clearing the variable x. Now we proceed to solve the equation for x:

  1. - 10 · x + 1 + 7 · x = 37     Given
  2. (- 10 · x + 7 · x) + 1 = 37   Associative property
  3. -3 · x + 1 = 37     Distributive property/Definition of subtraction
  4. - 3 · x = 36     Compatibility with addition/Definition of subtraction
  5. x = 12     Compatibility with multiplication/a/(-b) = -a/b/Definition of division/Result

By the knowledge and application of <em>algebraic</em> definitions and theorems, we find that the expression - 10 · x + 1 + 7 · x = 37 has a solution of x = 12. (Correct choice: C)

Anne and Willow are reading the copy of the same magazine for an assignment.
Kamila [148]

Answer:

Page number 74

Step-by-step explanation:

Let

x ---> the number of days

y ---> the number of pages read

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

we have

<em>Anne</em>

The slope is equal to

m=20\ \frac{pages}{day}

The y-intercept is equal to

b=14\ pages

substitute

y=20x+14 ----> equation A

<em>Willow</em>

The slope is equal to

m=22\ \frac{pages}{day}

The y-intercept is equal to

b=8\ pages

substitute

y=22x+8 ----> equation B

equate equation A and equation B

22x+8=20x+14

solve for x

22x-20x=14-8\\2x=6\\x=3\ days

Find the value of y

substitute the value of x in equation A or equation B

equation A

y=20(3)+14=74\ pages

equation B

y=22(3)+8=74\ pages

Rashawn puts $550 in an account earning 8% simple interest annually. How much will he have in his account after 6 years? i need
balandron [24]
It’s funny cause I have a friend named Rashawn
But y intercept would be 550 then multiply 8 by 6to get 48
So your answer should be $598 in 6 years

Solve the equation ?
Morgarella [4.7K]
6m+1=-23.  Do the inverse operation of adding 1 which is to subtract 1 to both sides =====> 6m+1-1= -23-1

You divide by 6 both sides  
6m/6=-24/6

m= -4
