Let x = amount for dog
let 2/3x-5 = amount for cat

x + 2/3x-5 = 195   combine x's
1 2/3x or 5/3x
5/3x-5 =195   add 5 to both sides
5/3x = 200   multiply both sides by 3
5x = 600   divided both sides by 5
x = 120

the cost of the dog is $120.00

How t solve polynomials????? HELPPPP EXAM TMRW!!!!
Alecsey [184]

Answer:

B) 1296 D) 729

Step-by-step explanation:

It's pretty straight forward, just put the values into your calculator. The question is asking to evaluate instead of simplifying, so this works. If you don't have a calculator, here are some tricks. Do them step by step in your head slowly if you have to, for fractions do them alone, and then divide them. Also in D, don't let the second value of (3)3)0 scare you, any exponent with a 0 in it is automatically 1! Hope I could help.

Suppose you drop a ball from 120 feet. The ball will bounce to 25 of its previous height. What is the total distance the ball tr
tamaranim1 [39]

Answer:

277.1 feets

Step-by-step explanation:

Drop height = 120 feets

Ball bounces 2/5 of previous height

Height after 1st bounce :

120 * 2/5 = 48 feets

Return distance = 48 feets

Height after second bounce :

48 * (2/5) = 19.2 feets

Return distance = 19.2 feets

Height after 3rd bounce :

19.2 * (2/5) = 7.68 feets

Return distance = 7.68 feets

Height after 4th bounce :

7.68 * (2/5) = 3.072 feets

Return distance = 3.072 feets

Height after 5th bounce :

3.072 * (2/5) = 1.2288 feets

(120 + (2*48) + (2*19.2) + (2*7.68) + (2*3.072) + 1.2288) = 277.1328

= 277.1 feets
