Answer: 10%
First off, you need to divide 1200 with 1080.
1200 - 1080 = 120.
Next, divide 120 with the original number.
120 / 1200 = 0.1
Then, multiply 0.1 with 100.
100 x 0.1 = 10
Finally, add a % at the end.
10 -> 10%
So in summary, your answer is 10%
Answer:
1) f(x) = x/8 - 7
2) f(x) = 1 - x/3
3) f(x) = 20 - 0.25x
4) f(x) = x + 7
Step-by-step explanation:
f^-1 = 8(x + 7)
x + 7 = y/8
x = y/8 - 7
f(x) = x/8 - 7
f^-1 = -3(x - 1)
y/-3 = x - 1
x = 1 - y/3
f(x) = 1 - x/3
f^-1 = 4(20 - x)
y/4 = 20 - x
x = 20 - y/4
f(x) = 20 - x/4
f(x) = 20 - 0.25x
f^-1 = x - 7
y = x - 7
x = y + 7
f(x) = x + 7
Here we have one large triangle with two smaller triangles drawn inside. The two smaller triangles are similar.
Thus, a/12 = 12/16, or a/12 = 3/4, or 4a=36, or a = 9.
Find b in the same way: b/20 = 9/12 (and so on).
Hello!
We will just do the math as shown below. We will use 4 7/7 to make the subtraction a bit easier.
4 7/7-4/7=4 3/7
Therefore, our answer is A) 4 3/7.
I hope this helps!
Answer:
C and B
Step-by-step explanation:
(6)
× 
← cancel 3x - 7y on numerator and denominator
= 
× 
= 
= 
→ C
(7)
÷ 
Factorise the denominators of both fractions
x² - 9 = x² - 3² = (x - 3)(x + 3) ← difference of squares
4x - 12 ← factor out 4 from each term
= 4(x - 3)
Then rewrite as
÷ 
← cancel 8 and 4 by 4
= ÷ 
• leave first fraction, change ÷ to × , turn second fraction ' upside down'
= × 
← cancel x - 3 on numerator and denominator
= 
× 
← cancel 2 and 6 on numerator and denominator
= 
→ B
