The definite value for p is 9.
But how are 8, 7, or 6 the value of p?
I personally think that you should contact the teacher who made this question. He/She probably meant to say What IS the value for p?
You use algebra to get the value for p:
20p-45 = 9p + 5p
Start solving from there.
Answer: option a. 5.46
Explanation:
The side lengths of the golden rectangle are in the proportion:
1
--------------------
golden number
The golden numbrer is:
1 + √5
-----------
2
So, the ratio is:
1
--------------
1 + √5
---------
2
And, using the properties of the division of fractions, that is equivalent to:
2
-------------
1 + √5
Since you have the given side t = 9, you can set the proportion, to find the unknown lenght, s:
2 s
--------- = ---------
1 + √5 t
2 s
--------- = ---------
1 + √5 9
And you can solve for s:
s = 9 * 2 / (1 + √5) ≈ 18 / (1 + 2.236) = 18 / (3.236) ≈ 5.56.
Which is the option a. 5.56
Answer:
$176
Step-by-step explanation:
$200 x 12%
12% --> 0.12
200 x 0.12 = 24 --> discounted off amount
200 - 24 = 176
Answer: A
Step-by-step explanation:
Subtract 2 from both sides of the equation
,
Simplify
, Subtract the numbers
, 9x from both sides of the equation, Combine like terms, Divide both sides of the equation by the same term, then you get your solution! I hope this helps.
2(6y − 3) = 20 + 6y
Use the distributive property, which states a(b - c) = ab - ac
We should get:
2*6y - 2*3 = 20 + 6y
Which can be simplified to:
12y - 6 = 20 + 6y
That means the mistake was in step 2. The student didn't multiply the numbers and instead added the numbers.
Your answer is: <span>Step 2: 12y-6=20+6y</span>
