Answer:

176 books

Step-by-step explanation:

Let's call the number of fiction books 'F', and the number of non-fiction books 'N'. Then, we can write the following system of equations:

eq1:

$F = 3N$

eq2:

$2*(F - 122) = (N - 24)$

$2F - 244 = N - 24$

$2F = N + 220$

Using the 'F' value from the first equation, we have:

$6N = N + 220$

$5N = 220$

$N = 44\ books$

$F = 3N = 132\ books$

The total number of books is:

$F + N = 132 + 44 = 176\ books$

Use substitution to solve<br>y=2x+1 <br>y=x-5

nirvana33 [79]

2x+1 = x-5
-x -x
X+1 = -5
-1 -1

X = -6

2(-6) +1= y
-12+1= y

-11 = y

-11 = -12+1
-11 = -6-5

A truck driver travels at 59 miles per hour. The truck tires have a diameter of 30 inches. What is the angular velocity of the w

Misha Larkins [42]

Answer:

$661.4\ rpm$

Step-by-step explanation:

we know that

1 mile=63,360 inches

step 1

Find the circumference of the wheels

$C=2\pi r$

we have

$r=30/2=15\ in$ -----> the radius is half the diameter

substitute

$C=2\pi(15)$

$C=30\pi\ in$

assume

$\pi =3.14$

$C=30(3.14)=94.2\ in$

Remember that

The circumference of the wheels represent one revolution

Convert 59 miles per hour to inches per minute

$59\ mi/h=59*63,360/60=62,304\ in/min$

using proportion find the number of revolutions

$\frac{1}{94.2}\frac{rev}{in}=\frac{x}{62,304}\frac{rev}{in}\\ \\x=62,304/94.2\\ \\x=661.4\ rev$

therefore

substitute

$62,304\ in/min=661.4\ rev/min=661.4\ rpm$

Solve the system of equations. \begin{aligned} & -5x+13y = -7 \\\\ & 5x+4y=24 \end{aligned} −5x+13y=−7 5x+4y=24 x= e

riadik2000 [5.3K]

Answer:

The solution of the given equations

x =4 , y = 1

Step-by-step explanation:

<u>Explanation</u>:-

<u>Step(l</u>):-

Given the system of equations -5x+13y = -7 ..(l)

5x+4y=24 ..(ll)

<u>Step(ll)</u>

Adding (l) and (ll) equations and cancelling '5x' terms we get

13y+4y = -7 +24

17y = 17

dividing '17' on both sides, we get

y=1

<u>Step(lll):-</u>

Substitute y=1 in equation (l) , we get

-5x+13y = -7

-5x + 13(1) = -7

subtracting '13' on both sides, we get

-5x +13 -13= -7 -13

-5x = -20

Dividing '-5' on both sides, we get

$x = \frac{-20}{-5}$

x = 4

<u>Conclusion</u>:-

The solution of the given equations

x =4 , y = 1
