The trick is to get the X all alone on one side. Start by subtracting 2 from both sides. This wqould give you -1/2X+2-2=-x+7-2 or simplified to -1/2x=-x+5. Next, add x to both sides to give you -1/2x+x=-x+5+x. This simplifies to +1/2x=5. Multiplying by 2 on both sides will get rid of the fraction. Therefore 2*1/2x=5*2. This simplifies to your final answer of x=10.

How are a common denominator and a common multiple alike and different?

grigory [225]

The Common Denominator is the bottom part of a fraction which has been matched to 2 or more fractions. For example 1/2 + 1/4 is easier if you use 2/4 + 1/4 = 3/4. You can also use it for 3/5 + 1 2/3 Becomes 3/5 + 5/3 (Improper fraction) and you change that to 9/15 + 25/15 = 34/15 = 2 4/15

hich uses the high-low method to analyze cost behavior, has determined that machine hours best predict the company's total ut

Crank

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
