is their any way I can get some more info on this problem
Step-by-step explanation:
Answer:
−1/3y+−4/3
Step-by-step explanation:
We need to solve for x.
How? Easy! :D
Step one: Flip the equation. (In class we call it the 'flip-flop'.) When you do this, you should have your equation look like this:
−3x−4=y
Step two: Add 4 to both sides of the equation. When you do this step, your problem should look like this:
−3x−4+4=y+4
−3x=y+4
Step three: Divide both sides by -3.
-3x/-3 = y+4/-3.
Step four: Wrap-up. What the answer is.
x = -1/3y + -4/3
Final step: OUR ANSWER!
x = -1/3 + -4/3
Hope this helped! :D

the 4th one
Step-by-step explanation:
37% out of 87% equals to 42.5
Answer:
Step-by-step explanation:
r is the common ratio.
Third term minus first term is 48.
a₃ - a₁ = 48
a₃ = a₁r²
a₁r² - a₁ = 48
a₁(r²-1) = 48
r²-1 = 48/a₁
Fourth term minus second term is 144.
a₄ - a₂ = 144
a₂ = a₁r
a₄ = a₁r³
a₁r³ - a₁r = 144
a₁r(r²-1) = 144
r²-1 = 144/(a₁r)
48/a₁ = 144/(a₁r)
r = 3
:::::
r²-1 = 48/a₁
a₁ = 6
:::::
a₆ = a₁r⁵ = 1458
