3x+4x+5x=90

combine like terms

12x = 90

divide by 12

x = 7.5

sides: 3(7.5) ,4(7.5) ,5(7.5)

    22.5, 30, 37.5

Help someone how do you solve this
Flauer [41]

Answer:

a = 10/3

Step-by-step explanation:

This can be written as:

x^{2} (x^{4})^{1/3}  = x^{a}

Anything to the power of 1/3 means to find the cube root. We can simplify this to:

x^{2} (x^{4/3}) = x^{a}

I just multiplied 4 and 1/3 (because of the second index law (a^{m})^{n}  = a^{mn}). Now, we can add the powers because the bases are the same and we are multiplying (first index law):

x^{10/3} = x^{a}

a = 10/3

Hope this helps!

x < -16, none of the solution sets are correct for the given equation.

Step-by-step explanation:

-1/4x > 4, multiply both sides by -4, don't forget when you multiply or divide by a negative you have to flip the sign.

x < -16
