Answer:
E) 31
Step-by-step explanation:
0 x 2 + 1 = 1
1 x 2 + 1 = 3
3 x 2 + 1 = 7
7 x 2 + 1 = 15
15 x 2 + 1 = 31
Answer:
x=5
Step-by-step explanation:
x-3x can be simplied to -2x and 3-9 can be simplied to -6
-2x+4=-6
Substract 4 from both sides
-2x=-10
Divide both sides by -2
x=5
Answer:
B-(x-1)
Step-by-step explanation:
You have to make them have a common denominator which is 12 then to solve for z you subtract 9/12from10/12 and you get 1/12 z=1/12
Answer:
Starting with the smallest, we will have; D , C, A, B
Step-by-step explanation:
Given;
A = 3/4
B = 5/6
C = 16/25
D = 9/15
Convert the fractions to decimal, to determine their sizes;
A = 3/4 = 0.75
B = 5/6 = 0.833
C = 16/25 = 0.64
D = 9/15 = 0.6
From the decimal form of the fractions, it be observed that,
B > A > C > D
Starting with the smallest, we will have; D , C, A, B
