125 minutes, or 2 hours and 5 minutes.

\frac{5}7 = \frac{x}{175}
cross multiply
5*175=7x
875=7x
\frac{875}7=x
125=x

Set up a proportion pages/pages= minutes/ minutes
7/175=5/x 
Note: x is the unkown variable or how long it will take him to read a 175 page book.
--Now do the math-- or cross multiply-- 
7(x)=175(5) 
reduce it down
7(x)=875
divide both sides by 7 in order to get variable x alone
x=125 
So it will take Jose 125 minutes to read the entire 175 page book.

Given ab/bc = fe/ed find ac
zubka84 [21]
Well, you can cancel out the b and e, so a/c = f/d.

Then you cancel out a on the left side of the equation by multiplying both sides by 1/a which then gives you c = f/ad.

Hope this helps!

givi [52]

Answer:

Step-by-step explanation:

Equation for the linear function has been given as,

y = 26 - 4x

For x = 1,

y = 26 - 4(1)

  = 26 - 4

  = 22

For x = 2,

y = 26 - 4(2)

  = 26 - 8

  = 18

For x = 3,

y = 26 - 4(3)

  = 26 - 12

  = 14

For x = 6,

y = 26 - 4(6)

  = 26 - 24

  = 2

Therefore, table for the function will be,

x               y

1              22  

2              18

3              14

6               2

Given that f(x)=x2-1 and g(x)=2x+8 find (g-f)(10)
irga5000 [103]

Answer:

<h2>(g-f)(10) = - 71</h2>

Step-by-step explanation:

f(x) = x² - 1

g(x) = 2x + 8

To find (g-f)(10) first find ( g - f)(x)

To find ( g - f)(x) subtract f(x) from g(x)

That's

( g - f)(x) = 2x + 8 - ( x² - 1)

Remove the bracket

( g - f)(x) = 2x + 8 - x² + 1

Simplify

( g - f)(x) = - x² + 2x + 9

To find (g-f)(10) substitute the value in the bracket that's 10 into ( g - f)(x)

That is

(g-f)(10) = -(10)² + 2(10) + 9

= - 100 + 20 + 9

= - 100 + 29

= - 71

Hope this helps you
