Q8 Q17.) Find the numbers.
Katarina [22]
Let x = the first number
      y = the second number
-------------------------------------
First: set up the equations.

Four times a first number: 4x
Decreased by a second number: - y
Is 4: = 4

4x - y = 4.

The first number increased by: x + 
three times the second number: 3y
is -25: = -25

x + 3y = -25.
------------------------
You can make your system of equations now.

4x - y = 4
x + 3y = -25

I would use substitution to solve these.

To do substitution, isolate a variable first, in one of the equations. I would probably isolate x in the second equation.

x + 3y = -25
x = -25 - 3y

Now, you can substitute -25 - 3y into 4x - y = 4, as x.

4x - y = 4
4(-25 - 3y) - y = 4

Now just solve for y.

-100 - 12y - y = 4
-13y = 104
y = -8

Now, you can put -8 as y into one of the original equations, I'll just use 4x - y = 4.

4x -  y = 4
4x - (-8) = 4
4x + 8 = 4
4x = -4
x = -1

So the first number is -1, and the second -2.

1/2(y+3)>1/3(4-y) with the steps
lys-0071 [83]

\frac{1}{2(y-3)}>\frac{1}{3(4-y)}=>3(4-y)>2(y-3)

12 - 3y > 2y - 6

12 + 6 > 2y + 3y

18 > 5y

y

y ∈ (-oo, \frac{5}{18})

Which sequence is represented by = 10 − 29 where x represents the term number and y represents the term?
lina2011 [118]

Answer:

X = 18

Step-by-step explanation:

Question: The sum of three numbers in order is 57. the equation that represents this is x (x 1) (x 2) = 57. which value of x from the set {16, 17, 18, 19} makes the equation true?

Answer: First you can use the equation to work out the value of x.

x + (x + 1) + (x + 2) = 57

Simplify the equation.

3x + 3 = 57.

Now solve the equation.

57 - 3 = 54

54/3 = 18

In short, The value of x is 18.
