Yes, they both are 2/7
Proof: Left-hand side
Simplify the following:
12/42
The gcd of 12 and 42 is 6, so 12/42 = (6×2)/(6×7) = 6/6×2/7 = 2/7:
Answer: 2/7
Right-hand side:
Simplify the following:
10/35
The gcd of 10 and 35 is 5, so 10/35 = (5×2)/(5×7) = 5/5×2/7 = 2/7:
Answer: 2/7
= <span>(-8x - 9)(-9x2 + 7x - 9)
= 72x</span>³ - 56x² + 72x + 81x² - 63x + 81
= 72x³ + 25x² + 9x + 81
In short, Your Answer would be: Option D
Hope this helps!
To answer this item, we are first to determine the common factor between the amounts of the cement, sand, and gravel.
If we let x be this factor, the amount of the cement would be x. Similarly, the amount of sand is 3x, and lastly the amount of gravel is 4x. Then, we establish the equation that would let us relate the amounts.
x + 3x + 4x = 480
Simplifying,
8x = 480
x = 60
Hence, the amount of cement is 60 kg, that of sand is 180 kg. Lastly, the amount of gravel is 240 kg.
Answer
Find out the how many comic books does Jim have.
To proof
Let us assume that comic books Jim have be u.
Let us assume that comic books Charlie have be v .
Let us assume that comic books bob have be w .
As given
jim has three times as many comic books as Charlie
thus
u = 3v
Charlie has two thirds as many books bob.
Thus
bob has 27 books .
i.e w = 27
Put this in the equation
Solving
v = 18
thus
comic books Charlie has be 18 .
Put v = 18 in the u = 3v
u = 3 × 18
= 54
comic books Jim has be 54 .
Hence proved
