This is the result of solving an equation to find a value(s) for the variable(s)which make the equation true.

Answers

Answer 1

Answer:

How the equation becomes true is given below.

Step-by-step explanation:

In an equation with one variable, the variable has a solution, or value, that makes the equation true.

An equation is a mathematical statement that asserts the equivalence of two expressions.
When an equation contains a variable, such as x, the variable is considered an unknown value.
The values of the variables that make the equation true are the solutions of the equation and can be found by solving the equation.
A solution of an equation can be verified, or checked, by substituting in its value for the variable in the equation.

For example, the assertion that “two plus five equals seven” is represented by the equation 2+5=7.

In many cases, an equation contains one or more variables. These are still written by placing each expression on either side of an equals sign (=). For example, the equation x+3=5, read “x plus three equals five”, asserts that the expression x+3 is equal to the value 5.

When an equation contains a variable such as x, this variable is considered an unknown value. In many cases, we can find the possible values for x that would make the equation true. For example, consider the equation we were talking about above: x+3=5. You have probably already guessed that the only possible value of x is 2, because you know that 2+3=5 is a true equation. We use an equals sign to show that we know the value of a given variable. In this case, we write x=2 (read as “x equals two”).

The values of the variables that make an equation true are called the solutions of the equation. In turn, solving an equation means determining what values for the variables make the equation a true statement.

The equation above was fairly straightforward; it was easy for us to identify the solution as x=2

If B1 = 3 m and B2 = 4m and the area is 7 m squared, what is the height?

Answers

the height is 1, because it's A=(b1 + b2)*h, the equation is this now 7=3 + 4)*h, you add 3 + 4 then that will give you 7, so now it should look like this 7=7*h, you do a fraction line under the 7 and 7*h each, and put a 7 as the denominator, so it kind of looks like this now 7 = 7*h

7 7 then you cancel the 7*h which leaves you to just h, so 7 divided by 7 will give you 1 so it looks like 1=h, PHEW

4 15/16 as a decimal

Answers

Hey there, 15/16 as a decimal is 0.9375, and all you do is add the 4 to 0.9375 and the decimal will become 4.9375. Therefore, 4 15/16 as a decimal is 4.9375

Final answer:

To convert a mixed number to a decimal, divide the fraction part and add it to the whole number.

Explanation:

To convert a mixed number to a decimal, you need to convert the fraction part to a decimal and then add it to the whole number. In this case, the mixed number is 4 15/16. To convert the fraction 15/16 to a decimal, divide the numerator (15) by the denominator (16). The result is approximately 0.9375.

Next, add the decimal 0.9375 to the whole number 4. The sum is 4.9375.

Therefore, 4 15/16 as a decimal is approximately 4.9375.
