Answer:
The value of x is approximately 0.3684.
Step-by-step explanation:
Given:
We need to solve the proportion.
Solution:
Now we can see that;
In given equation one number is fraction and other number is whole number.
Now To make whole number into fraction we will divide by 1.
hence the whole number will be equal to;
Now the new equation will be;
Now by cross multiplication we get;
Now dividing both side by 19 we get;
Hence the value of x is approximately 0.3684.
1. Answer:
C. 1050
Step-by-step explanation:
To find the area of a rectangle, it is length * width * height
25 * 7 = 175
175 * 6 = 1050
2. Answer:
C. 8
Step-by-step explanation:
To find the missing dimension of a rectangle, you can easily just divide the total by each dimension
540 divided by 7.5 = 72
72 divided by 9 = 8
3. Answer:
D. 31,400
(31,415.9)
Step-by-step explanation:
The radius of the cylinder is 20
The height of the cylinder 25
πr2h is the formula used to find the volume of a cylinder
Dividing by a fraction is the same as multiplying by its reciprocal. (flipped version)
6 and 9 are both divisible by 3, so we can simplify 6/9 = 2/3.
We can multiply across right now, but we might as well cross cancel.
Look at the numbers diagonal from one another...-3 and 3 are both divisible by 3, so we can change them to -1 and 1...2 and 2 are both divisible by 2, so we can change them to 1 and 1...
Any fraction over 1 can just be expressed as a whole number.
Our final answer...
If you were to multiply across, (maybe you don't like cross cancelling, idk?) you'd get the same answer, of course.
Answer:
y=3
Step-by-step explanation:
y + 3 = –y + 9
Add y to each side
y+y + 3 = –y+y + 9
2y+3 = 9
Subtract 3 from each side
2y+3-3 = 9-3
2y = 6
Divide by 2
2y/2 = 6/3
y =3
