Answer:
(-21)/20
Step-by-step explanation:
Simplify the following:
-(2 + 1/4) - 2/3 (1/5 - 2)
Put 2 + 1/4 over the common denominator 4. 2 + 1/4 = (4×2)/4 + 1/4:
-(4×2)/4 + 1/4 - 2/3 (1/5 - 2)
4×2 = 8:
-(8/4 + 1/4) - 2/3 (1/5 - 2)
8/4 + 1/4 = (8 + 1)/4:
-(8 + 1)/4 - 2/3 (1/5 - 2)
8 + 1 = 9:
-9/4 - 2/3 (1/5 - 2)
Put -2 + 1/5 over the common denominator 5. -2 + 1/5 = (5 (-2))/5 + 1/5:
-9/4 - 2/3 1/5 + (5 (-2))/5
5 (-2) = -10:
-9/4 - 2/3 ((-10)/5 + 1/5)
-10/5 + 1/5 = (-10 + 1)/5:
-9/4 - 2/3 (1 - 10)/5
-10 + 1 = -9:
-9/4 - 2/3×(-9)/5
-2 (-9) = 18:
(-9)/4 + 18/(3×5)
3×5 = 15:
(-9)/4 + 18/15
The gcd of 18 and 15 is 3, so 18/15 = (3×6)/(3×5) = 3/3×6/5 = 6/5:
(-9)/4 + 6/5
Put (-9)/4 + 6/5 over the common denominator 20. (-9)/4 + 6/5 = (5 (-9))/20 + (4×6)/20:
(5 (-9))/20 + (4×6)/20
5 (-9) = -45:
(-45)/20 + (4×6)/20
4×6 = 24:
(-45)/20 + 24/20
-45/20 + 24/20 = (-45 + 24)/20:
(-45 + 24)/20
-45 + 24 = -21:
Answer: (-21)/20
X > 9 is the answer. This is the correct answer because you would subtract 4 from each side of the equation, which would leave X on one side and nine on the other. The inequality remains the same since you are not dividing at all by any negative numbers
Answer:
3/32
Step-by-step explanation:
One approach to doing this probelm is to evaluate all three functions F, G and H at x = 2:
F(2) = 2(2) - 1 = 3
G(2) = 3(2) + 2 = 8
H(2) = (2)^2 = 4
3/8
Then (F/G)(2) = (3/8), and (F/G/H) = -------- = 3/32

Answer:
(a) -23
Step-by-step explanation:
The sequence is arithmetic with first term 3 and common difference -2. Then the general term is ...
an = a1 +d(n -1)
an = 3 -2(n -1)
and the 14th term is ...
a14 = 3 -2(14 -1) = 3 -2(13) = 3 -26
a14 = -23
Answer:
B. x = 14
Step-by-step explanation:
1. Add 9 to both sides of the equation
x - 9+9 = 5+9
x = 14
hope this helps :)
