Answer:1:10 is the ratio
Step-by-step explanation:if 7 are red then there are only 70 green left so there are 7 red to every 70 green or reduced is 1:10
Answer:
10:1
Step-by-step explanation:
70 green apples were sold, and 7 red apples were. So, the ratio of green to red would be 70:7. Reduce it and you get 10:1
In 2x + In 2=0
The solution to the equation log(2x) + log(2) = 0 is x = 1/4.
An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the liketerms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Using the properties of logarithms,
We can simplify the given equation as follows:
log (2x) + log (2) = 0
Combining the logarithms using the product rule of logarithms.
log((2x)2) = 0
Simplifying inside the logarithm.
log(4x) = 0
Using the definition of logarithms,
We can rewrite this equation as:
= 4x
Simplifying the left side.
1 = 4x
Dividing both sides by 4,.
x = 1/4
Therefore,
The solution to the equation log(2x) + log(2) = 0 is x = 1/4.

Answer:
x=1/4 or x=0.25
Step-by-step explanation:
Answer:
x = - 3, x = 1
Step-by-step explanation:
Given
n(x) = (x - 1)(x + 3)
To obtain the zeros, equate n(x) to zero, that is
(x - 1)(x + 3) = 0
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
Answer:
20,602 ft.
Step-by-step explanation:
We have been given that in the United States, the point of lowest elevation is 282 ft below sea level (Death Valley, California) and the point of highest elevation is 20,320 ft above sea level (Mount McKinley, Alaska).
To find the distance between the given points, we will subtract the lowest elevation from the highest elevation as:
Therefore, the distance between these points is 20,602 feet.
