What value of x makes this equation true?
6x=3x+18
Answer:
x= 6
Step-by-step explanation:
To find the value of x that makes the equation true, first shift all the x terms to one side of the equation.
6x -3x= 18
Simplify:
3x= 18
Divide both sides by 3:
x= 18 ÷3
x= 6

What value of x makes the equation [tex]\large\textit{6x=3x+18}[/tex] true?
[tex]\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}[/tex]
[tex]\dagger[/tex] When solving an equation, we need to make sure that variables are on one side of the equation, which is usually the left-hand side, and numbers are on the other side, which is usually the right-hand side, of the equation.
[tex]\bigstar[/tex] Since we have variables on the right-hand side as well as the left-hand side, we need to move all of them to the left-hand side, with the opposite operation:-
[tex]\sf{6x-3x=18}[/tex] Subtract 6x-3x:-
[tex]\sf{3x=18}[/tex] Now, divide by 3 on both sides:-
[tex]\boxed{\boxed{\sf{x=6}}}\checkmark[/tex]
We've found the value of x, but we also need to make sure our solution is correct.
We can do that by substituting 6 for x (into the original equation)
and seeing whether or not we have a true statement:-
[tex]\implies\sf{6(6)=3(6)+18}[/tex]
[tex]\implies\sf{36=18+18}[/tex]
[tex]\implies\sf{36=36}[/tex]
[tex]\bigstar[/tex] Since the LHS equals the RHS, our solution (x=6) is correct.

What value(s) of x will make x2 = 9 true?
.............................................................................
A. 81 and -81
B. V3
C. 3 and -3
D. 3
Thank you to anyone who answers !! :-)
Answer:
C.) 3 and -3
Step-by-step explanation:
The question is asking: "Which numbers can be multiplied by themselves and equal 9?" You can formally find this answer by taking the square root of 9, the opposite of squaring a number. Or, in this case, you can try the guess-and-check method. Remember, multiplying two negative numbers together results in a positive answer.
A.) is incorrect because 81 x 81 = 6561 and -81 x -81 = 6561.
B.) I'm assuming this answer is [tex]\sqrt{3}[/tex] (if it's not, there is still a better answer). This answer is incorrect because [tex]\sqrt{3}[/tex] x [tex]\sqrt{3}[/tex] = 3.
C.) is correct because 3 x 3 = 9 and -3 x -3 = 9.
D.) is incorrect because -3² also equals 9.

What is integer exponent?Exponents that should be integers are known as integer exponents in mathematics. It could be either a positive or negative integer. The positive integer exponents specify how many times the base number should be multiplied by itself in this case.
We have:
[tex]=\rm y^5y^3-(y^{-2})^4[/tex]
[tex]= \rm y^{5+3}-(y^{-2\times4})[/tex]
[tex]= \rm y^{8}-(y^{-8})[/tex]
[tex]= \rm y^{8}-\dfrac{1}{y^{8}}[/tex]
[tex]\rm y^5y^3-(y^{-2})^4 = y^{8}-\dfrac{1}{y^{8}}[/tex]
Similarly,
[tex]\rm (y^{-2})^4 + \dfrac{y^3}{y^{5}} = \rm \dfrac{1}{y^{8}} + \dfrac{1}{y^{2}}[/tex]
Thus, for the expression y5y3−(y−2)4 the correct value is in the first tile, and for the expression (y−2)4+y3y5 the correct value is in the fifth tile.

Answer:
B) d=4t
Step-by-step explanation:
let's look at two points
1. t=0, d = 0
2. t = 1, d = 4
slope = change in vertical axis (d)/ change in horizontal axis (t)
change in d = 4 = d₂-d₁
change in t = 1 = t₂-t₁
slope = 4/1 = 4
vertical variable = slope * horizontal variable + horizontal axis intercept
d = 4 * t + horizontal axis intercept
horizontal axis intercept is the vertical axis variable (d) when the horizontal axis variable (t) is at 0. at t=0, d=0
thus, d = 4 * t + 0
d = 4t (B)

Answer: The side highlighted is 6.3 units long
Step-by-step explanation:
You can use Pythagorean therum to solve this problem
a² + b² = c²
We already know the length of two of the sides, a and b. So we will replace those variables with the given values
2² + 6² = c²
And now we solve
2² + 6² = c²
4 + 36 = c²
c² = 40
√40 = 6.3
