X-4y=6. 5x+y=8

minus X from both sides

4y=6. 4x+y=8

minus y from both sides

3y=6. 4x=8

y=2

X=-2

I need to find the value of X
nirvana33 [79]

Answer:

17.7

Step-by-step explanation:

This figure is a pentagon - a shape with 5 sides. In a pentagon, the figure's angles add to 540.

100 + 7x-4 + 3x + 23 + 9x - 6 + 90 = 540

190 +19x + 13 = 540

203 + 19x = 540

19x = 337

x = 17.7

Wazma bought some new pants, but the 34 inch inseam was too long. If he wants the inseam to be 3013 inches long, how much length
KiRa [710]

The length of the inseam to be removed from the pant is 3 2 / 3 inches.

<h3 /><h3>How to find the length to be removed?</h3>

The length of the pant he bought is 34 inches and it was too long.

He wants the length to be 30 1 / 3 inches long.

Therefore, the amount of length to be removed can be calculated as follows;

34 - 30 1 / 3

30\frac{1}{3}  = \frac{91}{3}

Hence,

34-\frac{91}{3}=\frac{102-91}{3} =\frac{11}{3}=3\frac{2}{3}  inches

Therefore, the number to be removed is 3 2 / 3 inches

How long will it take $5500 to grow to $7400 at an interest rate of 5% it the interest is compounded continuouslyRound the numbe
Thepotemich [5.8K]

Answer:

 5.93 years

Step-by-step explanation:

The continuous compounding formula tells you the amount after t years will be ...

  A = Pe^(rt) . . . . principal P compounded continuously at annual rate r for t years

  7400 = 5500e^(0.05t)

  ln(7400/5500) = 0.05t . . . . divide by 5500, take natural logs

  t = 20×ln(74/55) ≈ 5.93

It will take about 5.93 years for $5500 to grow to $7400.

Owen’s bedroom has a perimeter of 46 feet. If the length of the bedroom is 11 feet, what is the width
AnnyKZ [126]

Perimeter of a rectangle is given by (2 × Length(l)) + (2 × Width(w)) = 2l + 2w

l= 11 feet

2(11) + 2w = 46

2w = 46 - 22 = 24

w = 24/2 = 12 feet

Width = 12 feet.
