Answer:
b = 10
-2d = -38
x = -1.2
Step-by-step explanation:
b = 10 and x = -1.2 only have one variable. You can divide -2 to both sides for -2d = -38 getting d = 19.
0.1 = 0.1 have no variable meaning that any number can be correct in the equation
1/3 ≠ 1/3 has a cross in the equal sign meaning that there is no correct answer for the equation.
Use tan because you are dealing with the opposite and adjacent sides
Identify the opposite, adjacent, and hypotenuse based on the 15 degree angle. From there plug in the variable x and 14 into your tangent equation which would be tan15=x/14. Solve for x using a calculator and your answer would be rounded to 3.8.
Answer:
Let the two numbers be x and y.
Then x + y = 20, and y = 20 - x.
Their product is what you get when you multiply the two numbers together, in other words xy, or x(20 - x). You can expand this out to get 20x - x².
The product of the two numbers will be maximum at the value

Answer:
- c) Four times x over four equals four over four; Division Property of Equality
===========================
Given equation and steps to solve it:
- 4(x + 1) = 8
- 4x + 4 = 8
- 4x + 4 - 4 = 8 - 4
- 4x = 4
- 4x/4 = 4/4 <u>This is the missing step</u>
- x = 1
All steps given above including the missing one. As we can see, we divided both sides by 4, so the justification for this step is Division Property of Equality.
Hence, the correct choice is C.
