5x - 9 ≤ 21
5x ≤ 21 + 9
5x ≤ 30
x ≤ 30 ÷ 5
x ≤ 6
Answer:
Consider this: factors that are the same that are in the numerator and denominator of a fraction cancel out.
e.g. 20/30 = [2(10)]/[3(10)] = 2/3 This is because the 10 present in the numerator exactly equals the 10 present in the denominator.
We can use the above principle for these types of problems!
If the projectile is fired at 422 mi/hr, and we want to convert this speed into m/s, we just need to go through the following process:
422 mi/hr * 1610m/1mi * 1hr/60min * 1min/60s = 189 m/s
Step-by-step explanation:
Answer:
x=47
Step-by-step explanation:
We can use the triangle bisector theorem
TK TV
----------- = -----------
YK YV
Substituting what we know
87.5 77
----------- = -----------
x-22 22
Using cross products
87.5 * 22 = 77 *(x-22)
Distribute
1925 =77x - 1694
Add 1694 to each side
1925 + 1694 =77x - 1694+1694
3619 = 77x
Divide by 77
3619/77 = 77x/77
47=x
