Answer:
x ≤ 2
Step-by-step explanation:
We are given the inequality:
First, get rid of the denominator by multiplying both sides by 2:
Add both sides by 6 then subtract both sides by x:
Then divide both sides by 3:
Therefore, the answer is x ≤ 2
Answer:
Step-by-step explanation:
time = 49 hours
speed = 7 miles/hour
speed = distance / time
∴ distance = speed × time
= 7 × 49
= 343 miles
Answer:
first create a bracket:
then solve the first bracket:
then open the remaining bracket:
carryout the subtraction operation:
Answer:
x = 15
Step-by-step explanation:
Assuming 3x and x-60 are in degrees, you can use:
cos(a) = sin(a+90)
To rewrite the equation as:
sin(3x) = sin(x-60+90)
sin(3x) = sin(x+30)
3x = x+30
2x = 30
x = 15
But, solving 3x = x+30 which simplifies to x=15 is not the only solution to this equation, as you can see in below picture. Finding all solutions is a bit more work, but maybe that is not required in your case.
