Answer: x = 2
Step-by-step explanation:
-6 + x = -4
Add 6 to each side
x = 2
Now, if you plug that into the equation, you can check it.
-6 + 2 = -4
Answer:

Step-by-step explanation:
Given:
Charges of one hour swimming class = $5
Maximum amount that parents are willing to spend for swimming = $100
To find: inequality representing the possible number of hours, a student could take swimming lessons
Solution:
An inequality compares two values such that either one value is less than, greater than, or not equal to another value.
Let x represents number of hours spend by a student in swimming class.
As maximum amount that parents are willing to spend for swimming is $100 and charges of one hour swimming class is $5,

Writing and solving an equation of ratios would seem to be the best way to go.
0.045 sec 3 sec

1 image x
Then 0.045x = 3, and x = 66 2/3 images, best rounded down to 66 images.
6.51 - 9.32h = 1.02
9.32h = 6.51 - 1.02 = 5.49
h = 5.49/9.32 = 0.589
Answer:
The height is 5 units
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the base and h is the height
30 = 1/2 (12) h
30 = 6h
Divide each side by 6
30/6 = 6h/6
5 = h
The height is 5 units
