Step-by-step explanation:
102
105
108
<u>111</u>
The function is add 3 or count by 3 from 102.
103
106
109
<u>112</u>
The function is add 3 or count by 3 from 103.
A)
you square both sides
by squaring the left side, you get rid of the square root leaving only x one that side. But you also need to square the other side because whatever you do to one side you have to do to the other.
Answer: x=o/a^2
b)
To get o on its own on one side you multiply a. You basically do the opposite of what a originally does to cancel it out. So originally, a is dividing o so if you do the opposite, a will multiply on both sides.
a X o cancels out the a, leaving only o.
But whatever you do to one side, you have to do to the other. so Vx (square root of x) has to also be multiplied by a.
Answer: Vx X a=o
c) this is basically the same as b).
apply what i said in b) to this and you will get your answer
to cancel out o, you multiply both sides by o.
because o is getting divided, you will have to do the opposite which is multiply o.
Answer: Vx X o=a
A = bh/2
12= bh/2
bh = 24
We need to find pairs that multiply to 24
Answer: b=3 and h=8
, b=6 and h=4, b=12 and h=2
Answer:
Zander starts with 7,000; Carly starts with 5,000
Step-by-step explanation:
1 - Visually solving
Looking at the final value (31,000) one could interpret the sums of the numbers tripled and doubled respectively would need to equate to 31,000.
Taking off the additional zeros could also prove beneficial. To get 31, one of the numbers tripled or doubled would need to either be 11 or 21. 11 is a prime number, so that can be cancelled out. 7 multiplied by 3 (triple) produces 21.
12 - 7 = 5. Solving for the leftover 5 which would be doubled, you would get 10.
10 + 21 = 31.
2 - Algebra
x - Zander; y - Carly
To begin with you should need the initial formula.
x + y = 12,000
Your second formula would then take into consideration the changes made to x and y
3x + 2y = 31,000.
Using process of elimination or substitution, (either method works), you will find x = 7,000 and y = 5,000
The answer is 5.5 because 66/12= 5.5, hope this helps..
