Answer:
The number of cats are 23 and the number of dogs are 10 at the shelter on tuesday .
Step-by-step explanation:
Let us assume that the number of cats be x .
Let us assume that the number of dogs be y .
As given
An animal shelter spends $1.50 per day to care for each cat and $8.50 per day to care for each dog.
Levi noticed that the shelter spent $119.50 caring for cats and dogs on Tuesday.
Equation becomes
1.50x + 8.50y = 119.50
Simplify the above
150x + 850y = 11950
Levi found a record showing that there were a total of 33 cats and dogs on Tuesday.
Equation becomes
x + y = 33
Two equations are
150x + 850y = 11950
x + y = 33
Multiply x + y = 33 by 150 and subtracted from 150x + 850y = 11950 .
150x - 150x + 850y - 150y = 11950 - 4950
700y = 7000
y = 10
Putting value of y in the equation x + y = 33 .
x + 10 = 33
x = 33 - 10
x = 23
Therefore the number of cats are 23 and the number of dogs are 10 at the shelter on tuesday .
Answer:
The Answers Are:
B. The variable h is the independent variable.
C. The number of hours worked causes a change in the number of dollars earned.
D. The variable d is the dependent variable.
Step-by-step explanation:
As you can see on the picture, the more hours you work, the more dollars you get.
d=19h
380 - 18% of 380
= 380 - (18/100)×380
= 380 - 68.4
= 311.6
First you have to order the set of values:
1, 1, 1, 2, 3, 3, 5, 7, 8, 8, 9
Now you just have to look for the middle value, which is 3.
Therefore your final answer is 3 :)
First, let's set up the equation:
"29 more than" is just
29+
"t" is
t
"equal to one" is
=1
put it all together to get
29+t=1
subtract 29 from both sides to get your answer:
t=-28
