Answer:
Option D is correct
Step-by-step explanation:
From the question, we have:
Required
The tree diagram
The selection process is as follows:
-- i.e. we write sack 2 as a subset of 1
-- i.e. we write sack 3 as a subset of 2
<em>The only tree diagram that illustrates this is: option D</em>
Answer:
27KG
Step-by-step explanation:
Mouse- M , Cat - C, Dog - D
M + C = 10 ----- (1)
M + D = 20 -------(2)
C + D = 24 --------(3)
(1) - (2) => C - D = -10 ---- (4)
(3) + (4) => 2C = 14
=> C = 7
Substitute C in (1) => M + 7 = 10
=> M = 3
Substitute M in (2) => 3 + D = 20
=> D = 17
Therefore C + M + D = 7 + 3 + 17 = 27KG
Answer:
f(2)=67
Step-by-step explanation:
In order to evaluate the function f(x)=x^4+6x^3+3 for x=2, you must replace all of the x's with the number two and then simplify:
f(2)=2^4+6(2)^3+3
f(2)=16+6(8)+3
f(2)=16+48+3
f(2)=16+51
f(2)=67
3x-5=13
Move -5 to the right side and change the sign
3x=13+5
Add 13+5
3x=18
Divide both sides by 3
X=6
Answer:
Distribute the 3 to x + 2, and distribute the 5 to (2x – 3).
Step-by-step explanation:
Given
Required
Reasonable first step
The reasonable first step is to open the brackets; i.e. distribute 3 to its bracket and 5 to its bracket.
This gives:
<em>Then the solution can be continued</em>
