three times the sum of a number and 4 is 8 less then one-half the number .write and solve an equation to find the number

Answers

Answer 1

Answer:

3(x + 4) = x/2 - 8

First, we can multiply both sides by 2:

6(x+4) = x - 16

6x + 24 = x - 16

Isolate x:

5x = -16 - 24

5x = -30

x = -6

Kenny is planning to plant a rectangular garden that is 10 feet longer than it wide. Kenny wants to find its width if its area is 200 square feet. Write an equation that models this problem?

Answers

Let the width be x, then the length is x + 10.
Area = length x width = x(x + 10) = 200
$x^(2) +10x = 200$
Solving the quadratic equation, we have that
x = 10 feet
i.e. the width is 10 feet.

Write and solve a system of equations to find the value of each variable

Answers

Answer:

Step-by-step explanation:

2x+5y=12

3x+4y=11

---------------

3(2x+5y)=3(12)

-2(3x+4y)=-2(11)

-----------------------

6x+15y=36

-6x-8y=-22

-----------------

7y=14

y=14/7=2

2x+5(2)=12

2x+10=12

2x=12-10=2

x=2/2=1

x=1, y=2. (1, 2)

---------------------

I just provided you an example of a system of equations and I already solved it for you.
