Answer:
x = -5/2
Step-by-step explanation:
3 ^ ( 4x-5) = (1/27) ^( 2x+10)
Rewriting 1/27 as 3^-3
3 ^ ( 4x-5) = (3^-3) ^( 2x+10)
We know that a^b^x = a^(b*c)
3 ^ ( 4x-5) = (3) ^(-3*( 2x+10))
3 ^ ( 4x-5) = (3) ^( -6x-30)
The bases are the same so the exponents are the same
4x-5 = -6x-30
Add 6x to each side
10x -5 = -30
Add 5 to each side
10x -5+5 = -30+5
10x = -25
Divide each side by 10
10x/10 = -25/10
x = -5/2
Answer:
Thomas has 45
Emma 30+45=75 pound
Step-by-step explanation:
Ratio is 3/5
Tomas receives x money
Emma receives x+30
3/5=x/30+x
3(30+x)=5x
90+3x=5x
90=5x-3x
90=2x
x=90/2=45
Thomas has 45
Emma 30+45=75 pound
45/75=3/5
