18= +5+x
x=3
If you do 3•5, you get 15.
Then do 3+15, you get 18.
Answer:
2x+5
Step-by-step explanation:
The answer is in the question.
2 and x is 2x and plus 5 is +5.
Equation:
89.50=2.35c+5.50d
If theres 22 dogs and cats in total you can plug in number less than 22 for c(# of cats) and d(# of dogs).
So we try pats numbers 8 cats and 14 dogs so
89.50=2.35(8)+5.50(14)
89.50=18.8+77
89.50=95.8
So pats numbers were wrong so we try different numbers
So i started pluging in numbers from under 22 so i got c is 10 and d is 12 lets try it with the equation
89.50=2.35(10)+5.50(12)
89.50=23.5+66
89.50=89.50 so it works the answer to how many number of dogs and cats is 12 dogs and 10 cats
Hint: Try using the Pythagorean thereom to solve it.
