If we take these numbers we can set it up in crops multiplication form to find the answer:

80. 180
—— = ——- then we cross multiply
100 x making 80x= 18000 then divide 18000 and 80 to get 225 meaning x=225 so Daniels book is 225 pages long

225 pages, its correct answer i did the math

180/80
x    /100
cross multiply;
180*100=18,000
divide with the amount left
18,000/80=225

5/6+2/9= in simplest form I NEED this plz help
tensa zangetsu [6.8K]

Answer: 1  1/18

Step-by-step explanation: 5/6 + 2/9 I know this might seem like common, but <em>the </em><em>Numerator is the top number of a fraction</em><em> and the </em><em>Denominator is the bottom a fraction.</em> When the numerator and the denominator are the same such as 5/5 the fraction equals one (I know its real fancy). When you're multiplying a fraction that equals on by another fraction its really just multiplying by a fancy looking 1 that's disguised as a fraction such as  5/5. If you simplify it it goes to the fraction it was as long it was simplified to the max  (5/5 x 1/2 = 5/10= 1/2)

  • First, you need to find a like denominator,  which is 18
  • Then, you got to multiply each fraction to make them have common denominators ...multiply 5/6 by 3/3  ( 3/3 is just  a fancy way of saying one) 5/6 x 3/3 = 15/18....multiply  2/9 by 2/2 (which is just another fancy way of saying one ) 2/9 x 2/2=4/18
  • Next you add them but only the numerator  15/18 + 4/18 = 19/18
  • Finally, you change the the fraction into a mixed number 1 and 1/18

Write the equation in slope intercept form y+4=-(x-7)/ Please help I don't get this and I have a final on thursday.​
frez [133]

Answer:

y=-x+3

Step-by-step explanation:

we have

y+4=-(x-7)

This is the equation of the line in point slope form

The equation of the line in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

Convert the equation to slope intercept form

remove the parenthesis right side

y+4=-x+7

subtract 4 both sides

y+4-4=-x+7-4

y=-x+3 ---> equation in slope intercept form

Which is an exponential decay function
Vikentia [17]

Answer:

Step-by-step explanation:

The last answer choice is the correct one.  The common ratio here is 0.7, which is between 0 and 1, an important criterion for recognizing an exponential decal function.  Every time x increases, f(x) will decrease.
