Consider this option:
1. rule: the equation will be the same if the both its parts are multiplied by one number ('0' is not included!).
2. using the rule, described upon:
-3x-2y=-7 (*(-1));
6x+4y=14 (*2);
-6x-4y=-14 (*(-2)).
Note, that not all the ways are described.
It took him 12 mins to bike the trail because it implies that you bike faster than jogging so the time should be shorter hence bike twice as fast as jogging
An equation is formed of two equal expressions. The value of x in the given exponential equation is 10. The correct option is 10.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
In the given exponential equation 
, It can be observed that the base of both the sides of the equation is the same, therefore, 5. Therefore, the equation can be written as,
Since the base on both the sides are the same, comparing the exponential values on both sides,
x - 2 = 8
x = 8 + 2
x = 10
Hence, the value of x in the given exponential equation is 10.

Answer:
4:5
Step-by-step explanation:
since there are 4 oranges bought for every 5 apples, the ratio of oranges to apples sold is 4:5
Answer:
7x + 5.6z
Step-by-step explanation:
To simplify any expression we use PEMDA ( order of operation)
Parenthesis
Exponents
Multiplication and division
Addition and subtraction
7x + (5.6) z
Here we have 5.6 inside the parenthesis
We multiply 5.6 with z
so it becomes 5.6z
7x + 5.6 z
Both terms 7x and 5.6z have different variable so they are not like terms
We cannot combine unlike terms, so we leave as it is
7x + 5.6z
