Step-by-step explanation:
how could we get 30x^2?
6x × 5x
<em>so</em><em>,</em>
x^2 +6x+5x+30=0
x (x+6) +5 (x+6)=0
(x+6)(x+5)=0
(x+6)=0/(x+5)=0
x=-6 or x=-5
Step-by-step explanation:
The first thing we must observe is that the hourly rate for each candle is:
<em />
<em>scented candles:
</em>
(1/12) / (20/60)
Simplifying:
= (1/12) / (10/30)
= (1/12) / (5/15)
= (1/12) / (1/3)
= (3/12)
= (1/4) inches / hour
<em>Unscented candles:
</em>
(1/6) / (30/60)
Simplifying:
= (1/6) / (15/30)
= (1/6) / (3/6)
= (1/6) / (1/2)
= (2/6)
= (1/3) inches / hour
Answer:
The unscented candles burn faster at a rate of:
(1/3) inches / hour.
Answer:
5
Step-by-step explanation:
i dont see how you get 6 but it's 5
To find the value of X, simply know that for this parallelogram, the angles on each end that are diagonal with respect to each other are the same. And knowing that the angles in a parallelogram add up to equal 360 degrees. Simply make an algebraic expression equal to the value of 360 and then solve for x.
X + X + (X - 26) + (X - 26) = 360
2X + X - 26 + X - 26 = 360
4X - 52 = 360
4x = 412
X = 103.
The value for X, I believe would be 103 degrees. You can verify this by plugging in the value into both expressions, X and X-26 and see that if adding all the expressions together does it equal 360 degrees.
Answer:
Step-by-step explanation:
a) <u>Jamal spent:</u>
<u>Isaiah spent:</u>
<u>The equation is:</u>
b) <u>Solving the equation</u>
- 2x = 3x - 6.75
- 3x - 2x = 6.75
- x = 6.75
c) <u>Jamal's items cost </u>
<u>Isaiah's items cost </u>
- $6.75 - $2.25 = $4.50 each
