<em>Step 1: Subtract x from both sides. </em>
1/3x +4− x =x −2− x
= -2/3 x +4 = -2
<em>Step 2: Subtract 4 from both sides</em>.
-2/3x + 4− 4 =−2− 4
-2/3x = -6
<em>Step 3: Multiply both sides by 3/(-2).</em>
( 3/-2 ) * (-2/3x ) = (3/-2) * (-6)
= 9
So , X=9
Answer:
48. Correct
49. Los Altos = 48
Westmoreland = -48
48 - ( -48)
48 + 48
96
The difference in elevation is 96 meters
50. Imperial = -18
Holtville = -3
(-18) ÷ (-3)
6
Imperial is 6 times as far below sea level than Holtville
Answer:
(0, -3)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
x - 4y = 12
x - 5y = 15
<u>Step 2: Solve for </u><em><u>y</u></em>
<em>Elimination</em>
- Subtract 2 equations: y = -3
<u>Step 3: Solve for </u><em><u>x</u></em>
- Define original equation: x - 4y = 12
- Substitute in <em>y</em>: x - 4(-3) = 12
- Multiply: x + 12 = 12
- Subtract 12 on both sides: x = 0
<u>Answer </u><u>:</u>
This figure consists of two shapes that are a rectangle and a square . We will first find the area of rectangle then the square then add them . Let's work on this together ,
- Breadth of rectangle = 4 cm
- Length of rectangle = 4 + 5 + 3
- Length = 12 cm
- Area of rectangle = 12 × 4
- 48 cm²
Area of square ,
Total area of the figure ,
6:5 it's basically just like a fraction that you're reducing.
