4x + 15 = 6x + -11

Reorder the terms:
15 + 4x = 6x + -11

Reorder the terms:
15 + 4x = -11 + 6x

Solving
15 + 4x = -11 + 6x

Solving for variable 'x'.

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

Add '-6x' to each side of the equation.
15 + 4x + -6x = -11 + 6x + -6x

Combine like terms: 4x + -6x = -2x
15 + -2x = -11 + 6x + -6x

Combine like terms: 6x + -6x = 0
15 + -2x = -11 + 0
15 + -2x = -11

Add '-15' to each side of the equation.
15 + -15 + -2x = -11 + -15

Combine like terms: 15 + -15 = 0
0 + -2x = -11 + -15
-2x = -11 + -15

Combine like terms: -11 + -15 = -26
-2x = -26

Divide each side by '-2'.
x = 13

Simplifying
x = 13

X= 13 because you have to add the x all to the left side than minus eleven from both sides which would equal -2x=-26 then divide by -2 which would equal x=13

Evaluate the expression when q=5 and b=9.<br> a+4b
Ierofanga [76]

Step-by-step explanation:

a = 5

b= 9

a + 4b = ?

5 + 4×9 =

5 + 36 = 41

The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Multiply thru by 100:
15x + 10*5 - 10x = 11*5

---
5x = 5
x = 1 liter (amt. 15% oj needed)

Find the equation of the line with slope 3/7 and that passes through the point (14, 0). Write your answer in the form y = mx + b
Allushta [10]

Answer:

y = 3/7x - 6

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

Slope <em>m</em> = 3/7

Point (14, 0)

<u>Step 2: Find y-intercept </u><em><u>b</u></em>

  1. Substitute:                    0 = 3/7(14) + b
  2. Multiply:                        0 = 6 + b
  3. Isolate <em>b</em>:                       -6 = b
  4. Rewrite:                         b = -6

<u>Step 3: Write linear equation</u>

y = 3/7x - 6

Silvia buys 12 steaks that are each 34 of a pound. She spends a total of $90 on steaks. Complete each sentence. Silvia buys a to
scZoUnD [109]
I think in the first sentence, that should have been 3/4 instead of 34. Total amount of steak bought (lb)
                                        total amount = (3/4 lb/steak)(12 steak) = 9 lb
To find the total amount that Silvia spends for each pound of steak, we divide $90 by 9 and that will give us an answer of $10.
