The equation is 23.30 + 2.20x = 55.00
First you subtract 23.3 from 55 which is 31.7 and divide that by 2.2 which is 14.4090909 or 14ccd
Answer:
Let y represents the dog and x represents the Cat.
As per the Statement:
A total of 34 dogs and cats participated in the pet store’s adoption event.
⇒ x+y = 34 ......[1]
It is also given that the number of dogs that were adopted was 7 more than twice the number of cats.
"Twice times the number of cats" means 2x
"7 more than twice the number of cats means 2x + 7
⇒
Then, system of equations are;
x +y = 34
y = 2x + 7
Now, plot the graph of these equation as show below:
The point intersection is, (9, 25) which represents 9 cats and 25 dogs are participated in the pet store's adoption event.
Answer:
39
Step-by-step explanation:
1. (2(4)-5)(2(4)+5)
2.(3)(13)
3.39
22 in long left cause if you just subtract it<span />
2(3x+7)-5(x+3)=0
6x+14-5x-15=0
x-1=0
x=1
