3 (2x + 1) = 21
6x + 3= 21
-3 -3
6x = 18
Divide each side by 6, and x equals 3.
3 (2(3) + 1) = 21
3 (6 + 1) = 21
18 + 3 = 21
Hope this helps! Can I please have brainliest so I can level up? Thank you!
Answer:
\frac{-177}{286}
Explanation:
Given,
\left(\frac{3}{11}\times\frac{5}{6}\right)-\left(\frac{9}{12}\times \frac{4}{3}\right)+\left(\frac{5}{13}\times \frac{6}{15}\right)
ft(\frac{5}{22}\right )-\left(\frac{36}{36}\right)+\left(\frac{2}{13}\right)
{5}{22}\right )-1+\left(\frac{2}{13}\right)
{5\times 13-286+2\times 22}{286}
{65-286+44}{286}
{109-286}{286}
{-177}{286}
23.
Work:
5(6)-7
5(6)=30
30-7=23
Answer:
Option B
Step-by-step explanation:
Speed is distance moved per unit tine and is expressed as s=d/t
Making d the subject then
d=st
Where d is distance, s is speed and t is time taken in time.
Conversion
1 hour has 60 minutes hence 45 mins converted to hours will be 45/60=0.75
Substituting 0.75 hours for t and 170 mph for s then
d=0.75*170=127.5 miles due North
However, tge plane had initially moved 12.5 miles hence the relative distance due North will be 127.5-12.5=115 miles due North
