Fill in the missing reasons (one for each step). Given: 3x – 6y = 27; x = 5 Prove: -2 = y
JulsSmile [24]

Answer:

a. Given,

b. Substitution

c. Subtraction of equality

d. Division of equality

e. Symmetric property of equality

Step-by-step explanation:

Given expression,

3x - 6y = 27; x = 5

By substituting x = 5,

3(5) - 6y = 27

15 - 6y = 27

By subtraction property of equality,

-6y = 12

Division property of equality,

y = -2

By symmetric property of equality,

-2 = y

3/7​% of a quantity is equal to what fraction of the​ quantity?
ANTONII [103]

Answer:

3/700

Step-by-step explanation:

Let

x = the quantity

3/7% of x

= 3/7 ÷ 100 * x

= 3/7 × 1/100 * x

= (3*1)/(7*100) * x

= 3/700 * x

= 3/700x

3/7​% of a quantity = 3/700 of the quantity

A project to build a new bridge seems to be going very well since the project is well ahead of schedule and costs seem to be run
Alecsey [184]

Answer:

Scheduled Variance = $850,000.00

Schedule Performance Index = 1.05

Cost Performance Index = 1.11

Step-by-step explanation:

Note: See the attached excel file for the calculations of Total Actual Cost to Date, Budgeted Cost of Work Scheduled (BCWS), and Budgeted Cost of Work Performed (BCWP).

From the attached excel file, we have:

Total Actual Cost to Date = $15,300,000

Total BCWS = $16,170,000

Total BCWP = $17,020,000

Therefore, we have:

Scheduled Variance = Total BCWP - Total BCWS = $17,020,000 - $16,170,000 = $850,000.00

Schedule Performance Index = Total BCWP / Total BCWS = $17,020,000 / $16,170,000 = 1.05

Cost Variance = Total BCWP - Total actual cost to date = $17,020,000 - $15,300,000 = $1,720,000

Cost Performance Index = Total BCWP / Total actual cost to date = $17,020,000 / $15,300,000 = 1.11
