Answer:
x = - 1/2
Step-by-step explanation:
-3(x-4) = -9(x - 1)
1. Distributive Property
-3 * x -3 *-4 = -9 * x -9 * -1
-3x + 12 = -9x + 9
Hint: 2 negatives make a postive
-3x + 12 = -9x + 9
2. Subtract 12 on both sides
-3x + 12 - 12 = -9x + 9 - 12
-3x = -9x + -3
3. Add 9x on both sides
-3x + 9x = -9x + 9x + -3
6x = -3
4. Divide both sides by 6 to isolate the variable
6x/6 = -3/6
x = - 1/2
Check:
-3(-1/2-4) = -9( -1/2- 1)
3/2 + 12 = 9/2 + 9
3/2 + 12 ( we need a common denominator so...lets make it 2 )
3/2 + 12*2/1*2
3/2 + 24/2 = 27/2 = 13 1/2 = 13. 5
Now...
9/2 + 9 ( we need a common denominator so..lets make it 2 )
9/2 + 9*2/1*2
9/2 + 18/2 = 27/2 = 13 1/2 = 13.5
13.5 = 13.5 CORRECT!
27/2 = improper fraction
13 1/2 = mixed number
13.5= decimal form

What is 365 divide by 3
Answer:
121.666667
Step-by-step explanation:
When 365 is divided by 3 the result or quotient is 121.66.
To calculate 365 divided by 3, we can perform long division:
Set up the division problem.
Determine how many times 3 can fit into the first digit of the dividend (3). The answer is 1.
Bring down the next digit (6) to the right of 3.
Determine how many times 3 can fit into the new number (36). The answer is 12.
Now, bring down the next digit (5) to the right of 12.
Determine how many times 3 can fit into the new number (53). The answer is 17.
Since there are no more digits to bring down, the division is complete.
The final result is: 365 ÷ 3
= 121.666...
Hence, 365 is divided by 3 to get 121.66.

If the 2 in 506,092 moved 2 places to the right what would it b
Answer:
The two will retain its unit place value
Step-by-step explanation:
We are given the number 506,092
Which is stated in words as
"Five hundred and six thousand and ninety two"
2 represents 2 units in the number
When we shift 2 by two places to the right, the number becomes
50,609,002
We can still see that "two" still retains it unit place value and the whole number now reads fifty million six hundred and nine thousand and 2

van purchased a DVD player on sale the original price was $171.50 the sale price was $149.37 what is the first step finding the percent markdown find the percent markdown
Answer:
12.90%
Step-by-step explanation:
Given ;
Original price = 171.50
Sale price = 149.37
To find the % markdown :
Markdown = Purchase price - sale price
171.50 - 149.37 = 22.13
(Markdown / purchase price) * 100%
(22.13 / 171.50) * 100%
0.1290379 * 100%
= 12.90%

-10 is the difference between 7 and
another number. Find the two possible
numbers.
Answer:
-3 and 17
Step-by-step explanation:
Let the number be = x
x - 7 = -10
x = -10 + 7
x = -3
OR
7 - x = -10
- x = -10 - 7
- x = -17
x = -17/-1
x = 17
The two possible numbers are -3 and 17

m∠ABC=(6x+8)° and m∠DEF=(12x-8)°.
If ∠ABC and ∠DEF are supplementary,what
is the measure of each angle?
Answer:
m∠ABC = 68°
m∠DEF = 112°
Step-by-step explanation:
Supplementary angles are angles that add up to 180 degrees (they form a straight line).
If ∠ABC and ∠DEF are supplementary, that means that they add up to 180. We can write this in an equation:
(6x + 8) + (12x - 8) = 180Combine like terms.
18x = 180Divide both sides by 18.
x = 10Find the measure of each angle by substituting 10 for x into both expressions for the angles.
m∠ABC = (6x + 8)°
6(10) + 8 = 68°m∠DEF = (12x - 8)°
12(10) - 8 = 112°→ (6x + 8) + (12x - 8) = 180°
→ 6x + 8 + 12x - 8 = 180°
→ 18x = 180°
→ x = 180 ÷ 18
→ x = 10°
Now, we are given that m∠ABC = (6x+8) just subsitute the value of x in it .
→ m∠ABC = (6x + 8)
→ m∠ABC = (6 × 10 + 8)
→ m∠ABC = 60 + 8
→ m∠ABC = 68°
Similarly, subsitute the value of x in m∠DEF = (12x - 8)° we get :
→ m∠DEF = (12x - 8)°
→ m∠DEF = (12 × 10 - 8)
→ m∠DEF = 120 - 8
→ m∠DEF = 112°

Hari's weekly allowance varies depending on the number of chores he does. He received $22 in allowance the week he did 16 chores, and $16 in allowance the week he did 4 chores. Write an equation for his allowance in slope-intercept form.
9514 1404 393
Answer:
y = 0.5x +14
Step-by-step explanation:
If we let x and y represent the number of chores and Hari's allowance, respectively, then we have the two points (16, 22) and (4, 16). We can use the 2-point form of the equation for a line to find the equation.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (16 -22)/(4 -16)(x -16) +22 . . . . substitute
y = -6/-12(x -16) +22 . . . . simplify
y = 1/2x -8 +22 . . . . eliminate parentheses
y = 0.50x +14
