Answer:

x=-2 and y=2

Step-by-step explanation:

Do simultaneous equations

-8x + 4y = 24 (multiply everything in the equation by -7)

-7x + 7y = 28 (multiply everything in the equation by 8)

56x - 28y = -168

-56x + 56y = 224

(add equations, ie add 'x' parts, 'y' parts, and numerical parts)

28y = 56

∴y = 2

-8x + 4y = 24

-8x + 4(2) = 24

-8x = 16

∴x=-2

Lemme know if you have questions :D

Consider this system of equations and the partial solution below.

Inga [223]

The first equation will turn into -18x -6y = -18, and the second equation will turn into 14x + 6y = 18. The y terms will cancel out when you add the equations together.

Answer:

D) 5985

Step-by-step explanation:

Total area: 150×100 = 15000

Area for stars: 6×6 = 36

Total area - area for stars = area for fans

15000-36= 14964

14964ft² for fans, each takes up 2.5 ft²

14964 ÷2.5 = 5985.6 fans

Since we can't have 0.6 of a person, we round down to 5985 fans

sixteen men working 9 hrs a day can complete a pice of work in 14 days .How many more men working 7 hrs a day would complete the

nordsb [41]

Answer:

8 more men are needed to complete the job

Step-by-step explanation:

Proportions

This problem can be solved by step-by-step reasoning applying proportions:

16 men working 9 hrs a day complete the job in 14 days
16 men working 1 hr a day complete the job in 14*9 days

The above statement stands because the fewer hours of work, the more time the job needs to be completed. Let's continue.

1 man working 1 hr a day complete the job in 14*9*16 days

The same reasoning applies here, fewer men=more days.

Now for the second condition. Increase the hours/day:

1 man working 7 hrs a day complete the job in 14*9*16/7 days

More hours/day=less days to complete the job

x men working 7 hrs a day complete the job in 14*9*16/(7*x) days

We know this last time is 12 days, thus:

$\displaystyle 12=\frac{14*9*16}{7*x}$

Solving for x:

$\displaystyle x=\frac{14*9*16}{7*12}=\frac{2016}{84}=24$

24 men are needed now, this is an increase of 24-16=8 more men

8 more men are needed to complete the job

Write an equation through the points (-3,7) and (1,-1)

Aliun [14]

The slope is -2.

The slope is the rise over the run. Because the line goes down from left to right, it makes the value negative. For every one the it moves to the right, the line goes down two units.
