Answer:
x > 15
Step-by-step explanation:
So here we have to find the value of x
So, Subtract 5 from both sides;
-10x < -5 - 145
Now collect like terms,
-10x < -150
Divide both sides by -10
x > 15
The sign changes because if an equality is divided by a negative number the sign automatically changes.




The constant of proportionality is thus
45; the unit rate is
45 miles per hour.
The relationship between the time t (in hours) and the distance d (in miles) is thus
Answer:
Step-by-step explanation:
You have to use Pythagorean theorem
12^2+20^2 = x^2
sqrt(144*400) = x^2
sqrt(544) = x
X = 4 sqrt(34)
