Answer:
15 have only a dog
5 have a dog and a cat
9 have only a cat
Step-by-step explanation:
20 + 14 = 34, there there are only 29 students, so 34 - 29 or 5 have both a dog and a cat
15 have only a dog
5 have a dog and a cat
9 have only a cat
Step-by-step explanation:
<u>to show how many tickets were sold:</u>
x = upper floor tickets
y = main floor tickets
x + y = 2000
<u>to show total amount of revenue:</u>
25x + 40y = 62,000
<u>Finding answer using both equations:</u>
x + y = 2000
multiply each side by 25
25x + 25y = 2000 × 25
25x + 25y = 50,000
25x + 40y = 62,000
-
25x + 25y = 50,000
-----------------------------------
15y = 12,000
^ this is column subtraction
<em>^ this column subtraction is done to isolate y so we can work with one value rather than 2</em>
15y = 12,000
divide each side by 15
12,000 ÷ 15 = 800
y = 800
x + y = 2000
x + 800 = 2000
x = 1200
Therefore 1200 upper-level tickets were sold
800 main floor tickets were sold
Answer: x=3
Step-by-step explanation:
7+5(x-2)=12
Open bracket
7+5x-10=12
Collect like terms
5x-3=12
5x=12+3
5x=15
X=15/5
X=3
Answer:
48
Step-by-step explanation:
Here we will show you how to calculate 8 divided by 1/6. We will give you the answer in fraction form and in decimal form.
Here is 8 divided by 1/6 displayed mathematically in colors:
8
÷
1
6
The numbers in 8 divided by 1/6 are labeled below:
8 = whole number
1 = numerator
6 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
8 x 6
1
=
48
1
Thus, the answer to 8 divided by 1/6 in fraction form is:
48
1
To make the answer to 8 divided by 1/6 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
48 / 1 = 48
The answer is rounded to the nearest two decimal points if necessary.
48/1 is an improper fraction and should be written as 48.
X=2.85
it simplifies to 5x=14.25, and then 14.25/5=2.85
