Point y is between x and z on xz, yz= 3x-10 , xy= 2x-8 xz=17 find all missing length

lions [1.4K]

Answer:

Distance xy is 6

Distance yz is 11

Step-by-step explanation:

Given that the full length between x and z, xz = 17

Point y is located along xz where :

yz = 3x-10

xy = 2x-8

A simple sketch to show the distance and points can be;

x----2x-8---------y------3x-10-----------z

-----------------------17-----------------------

So you can see from this sketch that;

(2x-8) +(3x-10) = 17

2x-8+3x-10=17

5x-18=17

5x=17+18

5x=35

x=35/5 = 7

x=7

Distance xy=2x-8 = 2(7)-8 = 14-8 = 6

Distance yz=3x-10 = 3(7)-10 = 21-10 =11

Kendra has $6.00 in dimes and quarters. If she has 2 times as many quarters as dimes, how many of each coin does she have?

r-ruslan [8.4K]

Make a system of equations.

$\sf0.10d+0.25q=6$
$\sf~q = 2d$

Plug in 2d for 'q' in the first equation:

$\sf0.10d+0.25q=6$

$\sf0.10d+0.25(2d)=6$

Multiply:

$\sf0.10d+0.50d=6$

Combine like terms:

$\sf0.60d=6$

Divide 0.60 to both sides:

$\sf~d=10$

Now plug this into any of the two equations to find 'q':

$\sf~q = 2d$

$\sf~q = 2(10)$

$\sf~q = 20$

So she has 10 dimes and 20 quarters.
