3a + 3b-2c-2d
a= number of hearts
b= number of diamons
c= number of clubs
d= number of spades
if you draw 3hearts, 2 diamonds, and 1 spade, just replace a=3, b=2, c=0, d=1
3(3) + 3(2)-2(0)-2(1)
Multiply each term and add the results:
9+6-0-2 = 13
13 points
Answer:
X<-5
Step-by-step explanation:
1) open the brackets
2) take -35 to the other side with -10
where it turns to be -5X<-10+35
3) work out to find -5X<25
4) divide both sides by -5
to find X<-5
Answer:X=-15
Step-by-step explanation:
-4x/5=12
5x-4x/5=5x12
-4x=5x12
-4x=60
-4x/-4=60/-4
x=-15
For the sequence 2, 6, 18, 54, ..., the explicit formula is: an = a1 ! rn"1 = 2 ! 3n"1 , and the recursive formula is: a1 = 2, an+1 = an ! 3 . In each case, successively replacing n by 1, 2, 3, ... will yield the terms of the sequence. See the examples below.
