Answer:
x = -7
Step-by-step explanation:
5-x=12
To solve for x, you must first make the equation equal to x (to make x alone on one side).
5 - x = 12
-5         -5
-x = 7
-x(-1)=7(-1)
x = -7
 
        
             
        
        
        
Answer:
1)- Variable utilities cost per machine hour = 1.6 per machine hour
2)- Fixed cost = 1740
3)-Total cost on 1220 Machine hour will be
= 3692
Step-by-step explanation:
1) CALCULATE VARIABLE UTILITIES COST PER MACHINE HOUR :
Variable utilities cost per machine hour = Change in cost/high machine hour-low machine hour
=4076-3388/1460-1030
Variable utilities cost per machine hour = 1.6 per machine hour
2) Fixed cost = Total cost-variable cost
= 3388-(1030*1.6)
Fixed cost = 1740
3) Total cost on 1220 Machine hour will be (1220*1.6+1740) = 3692
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Since opposite and adjacent is given, we will use tan as trigonometric ratio.
Hence,
opposite = x , adjacent = 14 and  = 28
 = 28
So,

tan 28 = x / 14

The first answer is B because the bottom half of the proportions are how many km/minutes he CAN run, while the top half of the proportion is how many he WILL run.
He will run 60km in 285 minutes.
        
             
        
        
        
Answer:
60 seconds
Step-by-step explanation:
step 1.) find how many meters it falls per second
           40m / 4sec = 10m/s
step 2.) use the equation above to find in terms of the question
           10m/s for 6sec = 10 x 6 ====> 60 seconds
