Answer:
40
Step-by-step explanation:
In word problems, the word "of" usually means multiply. Thus, for example, 10% of $50 is $5. This is because we can write 10% as 0.10 or as 10/100 (which is 1/10) and then multiply: (1/10)(50) = 5
So, we often see equations like:
R = (1/2)D meaning R is 50% of D, or R is half of D
Let x = the number we want to find
This problem says:
"12 is 30% of what number?"
12 = (30/100) * x
12 = (3/10)x
(10/3)12 = x [multiply both sides by (10/3)]
40 = x
Checking (very important):
Is 12 = (3/10)(40) ?
12 = (3)(4) ?
12 = 12 ? yes
Hi again! I'm assuming that the straight line, which I believe is for y = -2 doesn't belong because everything else has two lines, I mean like it reflects off a certain point on the x or y axis but b) [as I like to call it] doesn't reflect on another axis.
Answer:
35/100
Step-by-step explanation:
P(green or black) = 3/20 + 4/20 = 7/20
7/20 = 35/100
<em>when </em><em>both </em><em>l </em><em>and </em><em>m </em><em>are </em><em>parallel</em><em> </em><em>then </em>
<em>(</em><em>4</em><em>x</em><em>+</em><em>7</em><em>)</em><em> </em><em> </em><em>=</em><em> </em><em>(</em><em>6</em><em>x</em><em>-</em><em>6</em><em>3</em><em>)</em>
<em>-2x </em><em>=</em><em> </em><em>-</em><em>7</em><em>0</em>
<em>-</em><em>x </em><em>=</em><em> </em><em>-</em><em>7</em><em>0</em><em>/</em><em>2</em>
<em>-x </em><em>=</em><em> </em><em>-</em><em>3</em><em>5</em>
<em>x </em><em>=</em><em> </em><em>3</em><em>5</em>
<em>hope </em><em>it </em><em>helps</em><em> </em><em>and </em><em>ur </em><em>day </em><em>will </em><em>full </em><em>of </em><em>happiness</em>
