Alyssa has 8 times more dolls thsn Haley. They have 1,791 dolls in all. How many more dolls does Alyssa have than Haley?

2 answers:

8 0

The equation would be 8x+x=1791. You add like terms (8x+x)= 9x so it would be 9x=1791.

Then, you divide both sides by 9 to get the x by itself, so now it is x=199. That is the number of dolls Haley has. To get the number of dolls Alyssa has, multiply Haley's dolls by 8, making Alyssa have 1592 dolls.

To get the number of dolls Alyssa has more than Haley, subtract 199 from 1592, you will get 1393. That is your final answer!

Adjacent Angles:
Adjacent angles are two angles that share a common vertex point and a common side. They basically sit right next to each other.

Given right triangle jkl, what is the value of cos(l)? five-thirteenths five-twelfths twelve-thirteenths twelve-fifths

The value of the cosine ratio cos(L) is 5/13

<h3>How to determine the cosine ratio?</h3>

The complete question is added as an attachment

Start by calculating the hypotenuse (h) using

h^2 = 5^2 + 12^2

Evaluate the exponent

h^2 = 25 + 144

Evaluate the sum

h^2 = 169

Evaluate the exponent of both sides

h = 13

The cosine ratio is then calculated as:

cos(L) = KL/h

This gives

cos(L) =5/13

Hence, the value of the cosine ratio cos(L) is 5/13
