Answer:

7 fiction and 23 non- fiction

Step-by-step explanation:

The number of non-fiction read was 5 less than 4 times the number of fiction books.

Assume fiction books are x.

An equation representing this would be:

x + (4x - 5) = 30

5x - 5 = 30

5x = 30 + 5

x = 35 / 5

x = 7 fiction books

Non-fiction books:

= 4x - 5

= 4 * 7 - 5

= 23 non - fiction books

Answer:

Line $y=-2x+3$ intersects line $y=x-5$

Step-by-step explanation:

We are given that

$y=-2x+3$

$y=x-5$

Subtract one equation from other then we get

$-3x+8=0$

$3x=8$

$x=\frac{8}{3}$

Substitute the value of x in first equation then we get

$y=-2(\frac{8}{3})+3=-\frac{16}{3}+3=-\frac{-7}{3}$

Hence, the solution $(\frac{8}{3},-\frac{7}{3})$ is the intersection point of two line equations .

Answer:Line $y=-2x+3$ intersects line $y=x-5$

Please really need the correct answer for this or I'll fail algebra 3

Answer:

$4\pi$

Step-by-step explanation:

S = Arc Lenth

θ = Radians

R = Radius

S = θR

So, now that we understand the formula, we will convert 72° into radians by introducing the equation $x*\frac{\pi }{180}$ , x = 72

S = $72*\frac{\pi }{180} * R$

given that R = 10

S = $\frac{72*10*\pi }{180}$

S = $\frac{720*\pi }{180}$

We simplify 720 as 180 goes into 720 4 times and we get

S = $4\pi$

Hope this helps
