So the two numbers can be represented as x and y
so x is first and y is second
y=2(x)-8
so y=2x-8
IF THEY ARE CONSECUTIVE
If they are consecutive numbers then
x+1=y
subtitute
x+1=2x-8
subtract x from both sides
1=x-8
add 8 to both sides and get
9=x
put it into the equation and get
y=2(9)-8
y=18-8
y=10
so x=9
y=10
IF X AND Y ARE CONSECUTIVE INTEGERS (1,2,3,4 not 2.3 or 1,3,5,8)
Answer:
7/4a + 1/3
1 3/4a + 1/3
Step-by-step explanation:
Answer:
JN = 32
Step-by-step explanation:
Δ JMN and Δ JKL are similar ( AA postulate )
then the ratios of corresponding sides are in proportion, that is
= 
( substitute values )
= 
= ( cross- multiply )
11 JN = 8(JN + 12)
11 JN = 8 JN + 96 ( subtract 8 JN from both sides )
3 JN = 96 ( divide both sides by 3 )
JN = 32
5 milk choc and 8 dark choc....total of 13 chocolates
P(1st pick is milk choc) = 5/13
do not replace
P(2nd pick is milk choc) = 4/12 which reduces to 1/3
P(both picks are milk choc) = 5/13 * 1/3 = 5/39 <== or 12.8%
