The error is due to different bases of logarithmic value on both sides.
What is logarithmic equation ?In, mathematics a logarithmic equation is inverse of exponential equation. That means, we can easily convert the logarithmic equation into exponential equation and vice versa. The basic form of the logarithm function can be written as [tex]log_{a}x[/tex] .
where, a is the base of function or equation
x = expression
Mathematically, if [tex]a^x = N[/tex] is an exponential function then, this can be converted to logarithmic function as [tex]log_aN = x[/tex].
There are many formulas that are given to us for solving several simple and complex problems based on logarithmic functions and logarithmic equations.

Gil traveled 4. 5 miles and continues at a speed of 62. 5 miles per hour. Andy has traveled 29. 5 miles per hour and continues at a speed of 50 miles per hour. If the cars continue at the same speed, how many hours will it take for andy and gill to travel the same number of miles
If Gil traveled 4. 5 miles and continues at a speed of 62.5 miles per hour and Andy has traveled 29.5 miles and continues at a speed of 50 miles per hour, then the number of hours it will take for Andy and Gill to travel the same number of miles is equal to 2.
The number of hours it will take for Andy and Gill to travel the same number of miles can be determined by using an algebraic expression.
An algebraic expression to find the number of hours can be given as,
4.5 + 62.5(x) = 29.5 + 50(x)
Here, x is equal to the number of hours.
Solving to find the value of x,
62.5x - 50x = 29.5 - 4.5
12.5x = 25
x = 25 ÷ 12.5
x = 2
Hence, the number of hours it will take for Andy and Gill to travel the same number of miles is calculated to be 2.

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.
A pair of triangles are said to be similar if two pairs of corresponding angles in those triangles are congruent. We can conclude that the third pair must also be equal if the first two angle pairs are. When all three pairs of angles are equal, the sides of the three triangles must also be proportionate.

What two different stores offer a sale on the same item, but one offers a coupon savings and the other offers a percentage-off discount? How can you tell which offer is better?
Answer:
Personally, I think it depends on the amount of the product you’re buying. If the product is expensive, you should go the store with a percentage-off discount. If the product is not expensive, you should go to the store with coupon savings.
Step-by-step explanation:
For example, if you’re buying a $5 toy with a $1 coupon and 10% off, you should chose the coupon. Because if you chose the discount, it doesn’t change a lot of things. However, if you’re buying a million dollar airplane(just kidding), then you should definitely chose the discount. Because a million dollar minus 1 changes nothing. But a 10% discount can decrease the cost by 1 hundred thousand! Isn’t that surprising? Hope you understand it.

What is meant by the supplementary angles?The term "supplementary angles" refers to a pair of angles which always add up to 180°. These two angles are termed supplements of one another. In other words, because unless Angle 1 + Angle 2 = 180°, angles 1 and 2 are supplementary. Angles 1 and 2 are referred to as "supplements" in this case.Supplementary angles are classified into two types.supplementary angles adjacentNon-adjacent supplementary anglesFrom the stated question;
∠A = 2X +27 and ∠B = 5X -1.

Harry needs to pay $ 125.55 in total for the 9.0 pizzas he ordered at $ 13.95 each.
To calculate how much Harry needs to pay, multiply the number of pizzas (9.0) by the cost of each pizza ($ 13.95).
Total cost = Number of pizzas × Cost per pizza
Total cost = 9.0 × $ 13.95
To find the product, we can treat 9.0 as a whole number and then multiply:
Total cost = 9 × $ 13.95
Now, calculate the product:
Total cost = $ 125.55
Harry needs to pay $ 125.55 in total for the 9.0 pizzas he ordered at $ 13.95 each.

Given that angle E and angle F are supplementary, the numerical measure of angle F is 74°.
What is the numerical measure of angle F?Supplementary angles are angles that sum up to 180 degrees.
Given the data in the question;
E and f are supplementaryMeasure of angle E = ( 9x - 38 )°Measure of angle F = ( 2x + 42 )°Numerical measure of angle F = ?Since E and F are supplementary, it means they sum up to 180 degrees.
Measure of angle E + Measure of angle F = 180°
Plug in the given values and solve for x
( 9x - 38 ) + ( 2x + 42 ) = 180
9x + 2x - 38 + 42 = 180
11x + 4 = 180
11x = 180 - 4
11x = 176
Divide both sides by 11
11x = 176
11x/11 = 176/11
x = 16
Now, the numerical measure of angle F will be;
Measure of angle F = ( 2x + 42 )
Measure of angle F = 2( 16 ) + 42
Measure of angle F = 32 + 42
Measure of angle F = 74°
