One number is four times another, and the sum of the two numbers is 155. What are the two numbers?
Rus_ich [418]

Answer:

A) N1 = 4*N2   OR N1 -4*N2 = 0

B) N1 + N2 = 155 multiplying B) by -1

B) -N1 -N2 = -155 then adding equation A)

A)  N1 -4*N2 = 0  adding the 2 equations

-5*N2 = -155

The numbers are N2 = 31  N1 = 124

What’s the square root of 8
kirill [66]

It's none of those, but the last is quite close to the exact value. You can find approximate square roots by trial and error: for sqrt(8), 2 is too small and 3 is too big, so try 2.5, 2.6, 2.7, 2.8, and 2.9. You'll find the answer is between 2.8 and 2.9.

Brianna spots an airplane on radar that is currently approaching in a straight line,

Using the slope concept, it is found that the distance the plane traveled from point A to point B is of 14,475 feet.

<h3>What is a slope?</h3>
  • The slope is given by the <u>vertical change divided by the horizontal change</u>.
  • It's also the tangent of the angle of depression.

At point A:

  • Altitude of 6700 feet, which is the vertical change.
  • The horizontal position we want to find is x_A.
  • The angle is of 16º.

Hence:

\tan{16^{\circ}} = \frac{6700}{x_A}

x_A = \frac{6700}{\tan{16^{\circ}}}

x_A = 23365.7

At point B:

  • Altitude of 6700 feet, which is the vertical change.
  • The horizontal position we want to find is x_B.
  • The angle is of 37º.

Hence:

\tan{37^{\circ}} = \frac{6700}{x_B}

x_B = \frac{6700}{\tan{37^{\circ}}}

x_B = 8891.2

Then, the distance is of:

d = x_A - x_B = 23365.7 - 8891.2 \approx 14475

Answer:

substitution method

x = 7

y = 2

Step-by-step explanation:

2x - 2y = 10

x = 7

substitute for x:

2(7) - 2y = 10

14 - 2y = 10

subtract 14 from each side of the equation:

-2y = -4

divide both sides by -2:

y = 2
