Answer:
x = 27
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define equation</u>
4x + 10 = 3x + 37
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 3x on both sides: x + 10 = 37
- Subtract 10 on both sides: x = 27
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 4(27) + 10 = 3(27) + 37
- Multiply: 108 + 10 = 81 + 37
- Add: 118 = 118
And we have our final answer!
Answer:32
Step-by-step explanation: 4 bikes every hour so multiply 4 times 8 which is 32
The new surface area will be 9 times the old surface area.
So A or #1
Answer:
7(2+3x)-3x and 4(3+3x)+2(1+3x)
Step-by-step explanation:
7(2+3x)-3x
= 14 + 21x - 3x
= 18x + 14
2(6x+7)+10x
= 12x + 14 + 10x
= 22x + 14
4(3+3x)+2(1+3x)
= 12 + 12x + 2 + 6x
= 18x + 14
7(2+3x)-3x and 4(3+3x)+2(1+3x) are equal expressions.
You would likely benefit far more from learning the definitions of "domain" and "range" than from being given the domain and range in each of these cases.
The domain of a function includes all values of the independent variable for which the function is defined (that is, for which there is a graph). In Case 1, x can have any real value, and so the domain is (-infinity, infinity).
The range of a function includes all values that the dependent value can have (that is, for which there is a graph). In Case 1, y can take on any real value, and so the range is (-infinity, infinity).
Contrast this case to Case 2. Here, y has only ONE value, so the range is simply y=2, or {2}. x can take on any value, so the domain is (-infinity, infinity).
