4x -6= 14
X=?
Answer:
5
Step-by-step explanation:
Given:
[tex]4x-6=14[/tex]
Add both sides by 6:
[tex]4x-6=14[/tex]
[tex]+6=+6[/tex]
[tex]4x=20[/tex]
Divide by 4:
[tex]\frac{4x}{4} =\frac{20}{4}[/tex]
Solve for x
[tex]x=5[/tex]
The value of x in the equation is 5.
Given is an equation 4x - 6 = 14, we need to find the value of x,
To find the value of x in the equation 4x - 6 = 14, we can follow these steps:
Add 6 to both sides of the equation to isolate the term with x:
4x - 6 + 6 = 14 + 6
4x = 20
Divide both sides of the equation by 4 to solve for x:
(4x)/4 = 20/4
x = 5
Therefore, the value of x in the equation 4x - 6 = 14 is 5.

The cost of 4 belts and 5 ties is $247. Each time costs 3 times as much as a belt. What us the total cost of 1 belt and 1 tie
Answer:
The total cost of 1 belt and 1 tie is $13 and $39 respectively.
Step-by-step explanation:
Given that,
The cost of 4 belts and 5 ties is $247.
Each tie costs 3 times as much as a belt.
Let the cost of a belt is x and that of a tie is y.
ATQ,
4x + 5y = 247 ...(1)
y = 3x ....(2)
Put the value of y from equation (2) in equation (1)
4x + 5(3x) = 247
4x + 15x = 247
19x = 247
x = 13
Put the value in equation (2)
y = 3x
= 3(13)
= 39
So, the total cost of 1 belt and 1 tie is $13 and $39 respectively.
A lion can run 18 mph faster than a giraffe. If a lion can run 50 mph how fast can the giraffe run?
Answer:
32
Step-by-step explanation:
its just 50 minus 18 and dont forget to borrow
Answer:
32mph
Step-by-step explanation:
So I think all you have to do is subtract 18 from 50 so 50 - 18 = 32mph
So in conclusion the giraffe can run 32mph if a lion is running at 50mph
Twelve is at least a number decreased by 7
Answer:
12 ≥ x - 7
Step-by-step Explanation:
When it says twelve is at least, it means that twelve is at least equal to something and it can also be greater. And when it says a number decreased by seven, it means a number, which is the variable x because it’s unknown, minus 7. All of this can be expressed as 12 ≥ x - 7, which is true because a number, which is x, minus 7, is the smallest “thing” that 12 can equal to.

PLEASE HELP!! Algebra 2
Answer:
No
Edit:
Yes, based on original equation. (Credit to greenpumpkin for correction)
Step-by-step explanation:
For this problem, we simply need to find the values of x that can make the equation true. So, let's begin by isolating the "x" variable.
sqrt(2x + 13) = x + 5
[sqrt(2x + 13)]^2 = (x + 5)^2
2x + 13 = x^2 + 10x + 25
0 = x^2 + 8x + 12
Note, we can remove the sqrt method by squaring both sides of the equation. Doing this, we see we have a quadratic equation meaning we can apply the quadratic formula to find solutions for x.
[-b +/- sqrt( b^2 - 4(a)(c) ) ] / 2a
Let a = 1, b = 8, and c = 12
[-8 +/- sqrt( (8)^2 - 4(1)(12) ) ] / 2(1)
= [-8 +/- sqrt( 64 - 48 ) ] / 2
= [-8 +/- sqrt(16) ] / 2
= [ -8 +/- 4 ] / 2
So, x = [ -8 + 4 ] / 2 and x = [-8 - 4 ] / 2
x = [-4] / 2 = -2 and x = [-12] / 2 = -6
Hence, the two values of x that can solve this quadratic equation are x = -2 and x = -6.
Therefore, we know that x = -6 is not extraneous, meaning it is a solution to our equation.
Cheers.
----------------------------------------------------
Edit:
Plugging the value of -6 back into the original equation, we get the following:
sqrt(2x + 13) = x + 5
sqrt(2(-6) + 13) = (-6) + 5
sqrt (1) = -1
1 != -1
Given that 1 cannot equal negative 1, we can say that x = -6 is an extraneous solution. (Credit to greenpumpkin for correction)
