Simplifying
1.8 + -3.7x = -4.2x + 0.3

Reorder the terms:
1.8 + -3.7x = 0.3 + -4.2x

Solving
1.8 + -3.7x = 0.3 + -4.2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4.2x' to each side of the equation.
1.8 + -3.7x + 4.2x = 0.3 + -4.2x + 4.2x

Combine like terms: -3.7x + 4.2x = 0.5x
1.8 + 0.5x = 0.3 + -4.2x + 4.2x

Combine like terms: -4.2x + 4.2x = 0.0
1.8 + 0.5x = 0.3 + 0.0
1.8 + 0.5x = 0.3

Add '-1.8' to each side of the equation.
1.8 + -1.8 + 0.5x = 0.3 + -1.8

Combine like terms: 1.8 + -1.8 = 0.0
0.0 + 0.5x = 0.3 + -1.8
0.5x = 0.3 + -1.8

Combine like terms: 0.3 + -1.8 = -1.5
0.5x = -1.5

Divide each side by '0.5'.
x = -3

Simplifying
x = -3

Rewrite the function by completing the square <br> f(x)=x^2-14x+63
Veseljchak [2.6K]

Answer:

f(x) = (x - 7)² - 14

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

  • Standard Form: ax² + bx + c = 0
  • Vertex Form: f(x) = a(bx - c)² + d
  • Completing the Square: (b/2)²

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = x² - 14x + 63

<u>Step 2: Rewrite</u>

  1. Separate:                              f(x) = (x² - 14x) + 63
  2. Complete the Square:         f(x) = (x² - 14x + 49) + 63 - 49
  3. Simplify:                                f(x) = (x - 7)² - 14

The sum of a students three scores is 217. If the first is 30 points more than the the second, and the sum of the first two is 1
nekit [7.7K]

Answer:

First score is 90

Step-by-step explanation:

Let A represent the first score

Let B represent the second score

Let C represent the third score

A+B+C=217 equation 1

If the first score A is 30 points more than the second,B

A=B-30  equation 2

Lastly,sum of A&B is 16 more than 2C

A+B=2C+16 equation 3

From equation 1

A+B=217-C equation 4

substitute for A+B in equation 3

217-C=2C+16

217-16=2C+C

201=3C

C=67

substituting C in equation 4

A+B=217-67

A+B=150

if the first score more than the first,then the first 90 while second 60 since A+B=150
