The formula to start with is (DC +CE) * CE = (AB + BE) * BE
Replace the letters with the numbers and equations:
(1 + x+4) * x+4 = (11 + x+1) * x+1
(x+5) * (x+4) = (x+12) * (x+1)
x^2 + 9x +20 = x^2 +13x +12
x^2 = x*x = 2x
11x+20 = 15x+12
20 = 4x+12
8 = 4x
x = 8/4
x = 2

please mark me brainliest so I can get to Ace rank
<span> At the beginning there are 3 dimes out of 10 coins:
P(first coin is a dime) = 3/10
After that there are 3 nickels out of 9 remaining coins:
P(second coin is a nickel) = 3/9 = 1/3
P(dime, then nickel) = P(first coin is a dime) x P(second coin is a nickel)
= 3/10 x 1/3
= 1/10
Answer:
1/10 . if im wrong im sorry </span>

Answer:
if you're talking about which number is in between 9 and 45 there's only one number 27
Answer:
Step-by-step explanation:
Generally equation of a line is given as
y=mx+c
Then given the point (x, y)=(0,2)
Therefore x=0 and y=2
y=mx+c
2=m×0+c
2=0+c
Then, c=2
Then intercept is 2
Also given the point (x, y)=(3,4)
x=3 and y=4 and c=2
y=mx+c
4=m×3+2
4=3m+2
4-2=3m
2=3m
Then, m=2/3
Then, the slope of the graph is 2/3
y=mx+c
Now, m=2/3 and c=2
The general equation of the line becomes
y=2/3x+2
Multiply through by 3
3y=2x+6
Then this is the equation of the line
