Let's see it...
-x+0+(-x)=0 ???
There is a + before the parenthesis, the sign is the same.
-x+0-x = 0
Since the x have equal sign, we add them to get -2x
We have 2x - 0 = 0
Move the zero to the right, so 2x = 0
Divide both for 2...
x = 0
Substitute 0 to x, so -0+0+(-0) = 0
0 = 0 the statement is true
Answer:
∠A = 88°
∠B = 92°
∠C = 88°
∠D = 92°
Step-by-step explanation:
∠A + ∠B = 180°
(2x + 4) + (3x - 34) = 180
reduce:
5x - 30 = 180
5x = 210
x = 42
∠A = 2(42) + 4 = 88°
∠B = 3(42) -34 = 92°
∠C = ∠A = 88°
∠D = ∠B = 92°
.t=50 +d so the answer is d
Answer:
5% compounded quarterly equals (1.0125)^4 -1=0.0509453369140625 or 5.09453369140625 % APR
250*(1.0125)^20=$320.51 at the end of 5 years
Step-by-step explanation:
Answer:
11.95 g / 6 hours
Step-by-step explanation:
drug dosage = 460 mg per kg per day
to be administered every 6 hours to a person who weighs 229 pounds
1 pound = 0.453592 kg
229 pounds = 229 × 1 pound = 229 × 0.453592 kg = 103.873 kg
dosage of drug needed for 103.873 kg
460 mg is to 1 kg per day
103.873 kg = 103.873 × 460 mg per 1 kg per day = 47781.58 mg per 103.873 kg per day
number of 6 hours in a day = 24 hours ÷ 6 hours = 4 times per day
dosage needed per 6 hours
47781.58 ÷ 4 = 11945.395 mg for every 6 hours = 11.95 g / 6 hours
