Answer:
1/2(6n - 12) = 3/4(4-8n)
3n - 6 = 3 - 6n
+6n +6n
9n - 6 = 3
+6 +6
9n = 9
n = 1
That means:
First step: Distributive property
Second step: Add 6n to both sides
Third step: Add 6 to both sides
Answer:
B. 20x larger
Step-by-step explanation:
3x10^5 = 300000
6x10^6 = 6000000
6000000/300000 = 20
So y=mx+b where m=the slope and b the y intercept is the equation you need to think about..
Now look at the equ. you have, y=254-40x, notice a similarity???
a.slope (m)=-40
y-intercept (b)= 254
b. To graph this, put a dot at (0,254) --this is the y-intercept remember, so thats where we are marking the y-axis at 254, then go down(b/c it's neg.) 40 over 1 (this is your slope remember, -40/1 or -40 over 1 ---which would =-40) and place another dot, connect the dots a voila! You've graphed it!!
c. So lets think, the y-intercept (254) is the <em>starting point</em>, when we've read zero hours we have 254 pages left. So the slope (-40) is the amount that we can read per hour, <em>for every hour we read, we subtract 40 pages.</em>
6 2/5 - 3 1/4 = 63/
20
= 3 3/
20
= 3.15
Answer:3.15
Hope this helps :)
Hello! I believe the answer is x = 320 ?
Here's how I got this :
Since 16 = x/20, why don't we multiply 16(20)? That way, we figure out what you divided by 20 to get 16.
16 (20) = 320
320/16 = 20 and 320/20 = 16!
