Answer:
-13
Step-by-step explanation:
5x − 3y − z
substitute x = −2, y = 2, and z = −3
5(-2) -3(2) - (-3)
multiply
-10 -6 +3
-16 +3
-13
It’s 23 because i did the calculation and i also did a little bit of this alit tule bi tof that and done

Answer:
C. 4.5 inches
Step-by-step explanation:
Given the following data;
Force, F = 10 pounds
Extension, e = 3 inches
First of all, we would determine the spring constant (k) using the following formula;
Force = spring constant * extension
10 = spring constant * 3
Spring constant = 10/3
Spring constant = 3.33 pounds per inches.
Next, we would find the extension of the spring when a force of 15 pounds is applied;
F = ke
15 = 3.33 * e
Extension, e = 15/3.33
Extension, e = 4.5 inches.
Answer:
112 hours and 50 mins
Step-by-step explanation:
Numbers of mins worked in a day = 7×60+30 =450 mins
Now number of mins worked in 15 days = 450×15
= 6750 mins
to convert mins into hours divide by 60
6750÷60 = 112.50
that means total number of hours worked in 15 days = 112 hours and 50 mins
