The answer should be -4,
7x2=14
2x-9=-18
14+ -18= -4
Got me there but i think its 325500
Let that certain number be 'n'
50% (n) = 39
50% ⇒ 0.5
0.5 (n) = 39
Divide both sides by 0.5
0.5n = 39
/0.5 /0.5
n = 78.
So that certain number is actually <em><u>78! :)</u></em>
CROSS CHECK:
50% of 78
0.5 × 78
= 39
Hope this helps! :)
Answer:
g ≥ -4
Step-by-step explanation:
4g + 2 ≥ - 14
-2 -2 Subtract 2 from both sides
4g ≥ -16
g ≥ -4 Divide both sides by 4
In 1 minute, bison runs 3520 feet
In 60 minutes, the bison would run
3520*60 feet
211200 feet per hour.
These are equivalent to;
40 miles per hour since 1 mile is equivalent to 5280 feet.
The bison is faster by 10 miles per hour
