Answer:

The solution is x=\frac{95}{4}=23.75.

Step-by-step explanation:

To solve the equation \log _{10}\left(4x+5\right)=2.

Use the logarithmic definition: \mathrm{If}\:\log _a\left(b\right)=c\:\mathrm{then}\:b=a^c

\log _{10}\left(4x+5\right)=2\quad \Rightarrow \quad \:4x+5=10^2

Simplify

4x+5=100

Next, solve for x

4x+5-5=100-5\\4x=95\\\frac{4x}{4}=\frac{95}{4}\\x=\frac{95}{4}

\text {Mass of earth =} 5.97 \times 10^{24} \text { kg}

\text {Mass of Venus =} 4.87 \times 10^{24} \text { kg}

\text {Difference = }5.97 \times 10^{24}  - 4.87 \times 10^{24}

\text {Difference = }(5.97 - 4.87) \times 10^{24}

\text {Difference = }1.1 \times 10^{24} \text { kg}


--------------- In Pure Text Format --------------
Mass of the earth = 5.97 x 10^{24} 
Mass of Venus = 4.87 x 10^{24}
Difference = (5.97 - 4.87) x 10^{24} = 1.1 x 10^{24} kg

Light bulbs usually cost 2$. They are on sale for 0.50 of the regular price. What is the sale price? Is this a better price than
Vinil7 [7]

Answer:

The sale price is $1

$1 is not a better price since there is a cheaper price of $0.7

Step-by-step explanation:

Original price is $2

The price now is 0.5 × $2 = $1

If the sale price was 0.35 of the original price;

It would be 0.35 × $2 = $0.7

$1 is not a better price since there is a cheaper price of $0.7
