Answer:
x = 45/7
Step-by-step explanation:
Write as an algebraic equation.
Look at each part in the word question : 0.7 of what number is 4 1/2
"0.7 of what number" can be written as 0.7x
The word "is" means equals.
0.7x = 4 1/2 <= The equation, using 'x' to represent the number.
To find the number, isolate 'x'.
0.7x = 
Convert mixed fraction to improper fraction
0.7x = 
Multiply the whole number by the denominator and add it to the numerator
0.7x = 
Now isolate 'x'
0.7x/0.7 = 
Divide both sides by 0.7
x = Simplify right side
x = 
Rewrite 0.7 as a fraction
x = 
To divide, you multiply a flipped fraction
x = 
Multiply across the top and across the bottom
x = 90/14 Reduce to lowest terms. Top and bottom are divisible by 2
x = 45/7 Answer
Answer:
B. 1395 sq. units
Step-by-step explanation:
Since the shape is an octagon, it is also composed of 8 triangles. If you solve the formula for the area of a triangle with those numbers and multiply it by the amount of sides you will have the total area.
Answer:
6s + 8c ≥ 900
Step-by-step explanation:
The library has <em>at least</em> 900 square feet available. It means <em>900 or more</em>.
If s is the number of study cubicles and c is the number of computer stations, the total space occupied by them is 6s+8c. That space is 900 or more square feet, so our inequality is 6s + 8c ≥ 900
Answer:
Well, there are four different colors in a pack of 52 cards. If one of the colors are green, depending on the card pack you have, I would say it is equal. Because 52/4 = 13 cards. Which is equal for every color.... So, the answer is probably equal, and close to 0. Because, it would be 1/4.
