Answer:
C and D are correct in my calculations, I'm confused.. ;w;
Step-by-step explanation:
4x + 9 + 79 - x + y = 180
4x - x + y + 79 + 9 = 180
3x + y + 88 = 180
3x + y = 180 - 88
3x + y = 92
y = 92 - 3x
A.) x = 64, y = 50
y = 92 - 3x
(50) = 92 - 3(64)
50 = 92 - 192
50 ≠ - 100
B.) x = 14, y = 152
y = 92 - 3x
(152) = 92 - 3(14)
152 = 92 - 42
152 ≠ 50
C.) x = 23.3, y = 22.1
y = 92 - 3x
(22.1) = 92 - 3(23.3)
22.1 = 92 - 69.9
22.1 = 22.1
D.) x = 14, y = 50
y = 92 - 3x
(50) = 92 - 3(14)
50 = 92 - 42
50 = 50
Answer:
assume z is equal to 5.
log(z^4/5) equals log(5^4/5) equals log(5^3) equals 2.096910013.
4 * log(5) - log(5) equals 2.096910013.
they give you the same answer.
this means they're equivalent.

Answer:
<u>[x] ≥ x</u>
Step-by-step explanation:
- The absolute value of a number is greater than or equal to itself
- Therefore, the correct answer is :
- ⇒ <u>[x] ≥ x</u>
Answer:
The number of DVD's is 6.
Step-by-step explanation:
Given:
Grace bought a television for $329.
Some DVDs for $5.75 each.
She spent total of $363.50
Now, to find out the number of DVD's Grace bought.
Let the number of DVD's be 
So, cost of DVD's =
Cost of television = $329.
Total amount spent = $363.50.
According to question:
Now, putting the equation to solve:

<em>Subtracting with 329 on both sides we get:</em>

<em>Dividing both sides by 5.75 we get:</em>

Therefore, the number of DVD's is 6.
