Answer:
-7/24 = r
Step-by-step explanation:
3/8 = r + 2/3
Subtract 2/3 from each side
3/8-2/3 = r + 2/3-2/3
3/8 - 2/3 = r
Get a common denominator or 24
3/8 *3/3 - 2/3 *8/8 =r
9/24 - 16/24 =r
-7/24 = r
Prove that sin 2x cos 2x=sin 3xx sin of the equation
3(x^2+10x+5)-5(x-k)=
3x^2+30x+15-5x+5k=
3x^2+25x+15+5k
for this to be divisible by x every term must include x or get eliminated
the problematic terms are 15 and 5k
to eliminate them they must equal 0 when added:
15+5k=0
5k=-15
k=-3
so A) -3 is the solution
-2x + x/4 + 1 = 5
-2x + x/4 = 4
-7x/4 = 4 (By using the same denominator)
x = -16/7
Answer:
The volume is 878.625
Step-by-step explanation:
First you can convert the mixed numbers and fractions into decimals to make life so much easier. 4 1/2 = 4.5 and 71/4 =17.75
Then simply mulitply 4.5 x 11 x 17.75 and get 878.625
