Log x + log 8 = 2    ???

Answers

Answer 1
Answer: To start we will use the sum to product rule of logs to make logx + log 8 = 2 -> log8x = 2. now assuming that this is log base 10 we will get rid of the log by raising both sides to the power of ten.

8x = 10^2
8x = 100
x = 100/8
Answer 2
Answer:

The solution to the equationlog(x) + log(8) = 2 is x = 12.5.

To solve the equation log(x) + log(8) = 2, we can use the properties of logarithms.

The equation can be simplified using the logarithmicproperty:

log(a) + log(b) = log(ab)

log(x) + log(8) = 2

log(8x) = 2

Rewrite the equation in exponential form:

10^2 = 8x

100 = 8x

To solve for x, divide both sides of the equation by 8:

(100)/(8) = x

12.5 = x

Therefore, the solution to the equationlog(x) + log(8) = 2 is x = 12.5.

Twice the difference of a number and 5

Answers

Answer:

Step-by-step explanation:

To express "twice the difference of a number and 5" algebraically, we can follow these steps:

Step 1: Let's represent the unknown number as 'x'.

Step 2: The difference of a number and 5 is obtained by subtracting 5 from the number, which gives us 'x - 5'.

Step 3: To find "twice the difference," we multiply the difference by 2, resulting in '2(x - 5)'.

Therefore, "twice the difference of a number and 5" can be expressed algebraically as '2(x - 5)'.

What is a radius f a circle with diameter of
240mm

Answers

r=120 mm
diameter 240 
so your answer is 120mm
well if you have the diameter then this is simple.
the diameter divided by 2 is the radius..
so 240/2=120
so the radius of the circle should be 120

Three restaurants sell turkey sandwiches in a small town: Delicious Deli, Garden Fresh, and Uptown Eatery.Delicious Deli sells 5 turkey sandwiches for $20.00.
Garden Fresh sells 2 turkey sandwiches for $8.50.
Uptown Eatery sells 3 turkey sandwiches for $13.50.
The graph shows Delicious Deli’s turkey sandwich sales, where x represents the number of turkey sandwiches sold, and y represents the total cost.

Answers

Answer:

$4 per Turkey

Step-by-step explanation:

Look on the graph and follow every number to the cost:

2 Turkeys: $8

4 Turkeys: $16

5 Turkeys: $20

Notice how there is a Pattern:

8, 16, and 20 are all multiples of 4  

4 x 2 = 8

4 x 4 = 16

4 x 5 = 20

So, the constant of proportionality for the coast per sandwich and Delicious Deli is $4
