Answer:

<h2><u>(9, 76)</u></h2>

Step-by-step explanation:

y = 7x + 13

y = 3x + 49

================

We can solve this in either of two ways:  Mathematically and graphically.

<h2><u>Math</u></h2>

Set the equations equal to each other (after all, y does equal y).

7x + 13 = 3x + 49

4x = 36

x = 9

Then use x = 9 to solve for y:

y = 7x + 13

y = 7(9) + 13

x = 76

<h2><u>Graph</u></h2>

Plot the two equations.  I use Desmos - its online and free.  The intersection of the two lines reveals to answer:  (9,76).  See the attachment.

lara31 [8.8K]

Answer:

The correct answer is "1287.02 ft"

Step-by-step explanation:

Given that:

T = 1200 ft

PI = 145+00

\Theta = 29.86°

or,

  = 0.5211 rad

As we know,

The radius of curve is:

⇒ T = R \ tan\frac{\Theta}{2}

1200=R \ tan(\frac{0.5211}{2} )

1200=R \ tan(0.267)

    R = 4494.38 \ ft

The length of curve will be:

⇒ L=R \Theta

       =449.38\times 0.5211

       =2342.01 \ ft

hence,

Station PT will be:

= PI-T+L

= 145-1200+2341.01

= 1287.02 \ ft

There were 3 times as many boys as girls in a museum. After 75 boys left and 25 girls entered, there were 2 times as many girls
Black_prince [1.1K]

Answer:

3x=y

3x-y=0

(y-75)+(X+25)=90

X+y=90+50

X+y=140

3x-y+X+y=0+140

4x=140

X=35(girls)

y=105(boys)

children were in the museum at first? *=35+105

<em>=140</em>

Write each number in expanded form one
andreev551 [17]
We need the numbers but here's an example.

Expanded form is:

100+20+4
So if you do it in simple form it's 124. Because there's 100, 20, and 4.
