Answer: \dfrac{7}{20}^{th}\ \text{Part}

Step-by-step explanation:

Given

George weeded \frac{1}{4} of the garden

When they both finish, \dfrac{2}{5} of the garden still needed to be weeded

Suppose Summer weeded  \dfrac{1}{x} part

\Rightarrow \dfrac{1}{4}+\dfrac{1}{x}=1-\dfrac{2}{5}\\\Rightarrow \dfrac{1}{4}+\dfrac{1}{x}=\dfrac{3}{5}\\\Rightarrow \dfrac{1}{x}=\dfrac{3}{5}-\dfrac{1}{4}\\\Rightarrow \dfrac{1}{x}=\dfrac{12-5}{20}=\dfrac{7}{20}

So, summer weeded \dfrac{7}{20}\ ^{th} part of the garden

Which equation(s) have x = –3 as the solution? log3(2x + 15) = 2 log5(8x + 9) = 2 log4(–20x + 4) = 3 logx81 = 4
baherus [9]

Answer:

log_3(2x+15)=2  and log_4(-20x+4)=3

Step-by-step explanation:

Plug it in and see!

log_3(2x+15)=2\\log_3(2(-3)+15)=2\\log_3(-6+15)=2\\log_3(9)=2\\\text{ This is a true equation because } 3^2=9\\\\\\log_5(8(-3)+9)=2\\log_5(-24+9)=2\\log_5(-15)=2\\\\\text{ Not true because you cannot do log of a negative number }\\\\log_4(-20(-3)+4)=3\\log_4(64)=3\\\text{ this is true because } 4^3=64\\\\\\log_x (81)=4\\log_{-3}(81)=4\\\text{ the base cannot be negative }\\\\\\\\\text{ There is only two options here} \\\\log_3(2x+15)=2 \text{ and } log_4(-20x+4)=3
