Answer:
16.65
Step-by-step explanation:
15 percent of 111 is the same as 15 per hundred of 111. We can therefore make the following equation:
15/100 = X/111
To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 111, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:
15/100 = X/111
X/111 = 15/100
X*111/111 = 15*111/100
X = 1665/100
X = 16.65
or
The work above shows the long way to explain how to calculate 15 percent of 111 in order to give you a foundation and better understanding of how to calculate percentage. In the future, you could use this simplified formula:
(Y * P)/100
In our problem "What is 15 percent of 111?", Y is 111 and P is 15:
(111 * 15)/100 = 16.65
And once again you see that the answer is 16.65.
Answer:
x = 3
y = -3
Step-by-step explanation:
We have two equations and are asked to solve for x and y.
y = -3x + 6
3y = -2x - 3
Substitute the y in the first equation in the second equation :
3(-3x + 6) = -2x - 3
Distribute :
-9x + 18 = -2x - 3
Solve for x by isolating it :
Subtract 18 from both sides :
-9x = -2x - 21
Add 2x to both sides :
-7x = -21
Divide -7 from both sides :
x = 3
Replace x in the first equation :
y = -3(3) + 6
y = -9 + 6
-9 + 6
y = -3
Answer:
Your question was very confusing but I tried...
Step-by-step explanation:
Area = 8,100 square feet
area of a square = a²
8,100 square feet = a²
√8,100 square feet = √a²
90 feet = a
total length each row of bookshelf is 4/5 of the length of the storage space.
90 feet * 4/5 = (90*4)/5 = 360/5 = 72 feet.
Area = (72 ft)²
Area = 5,184 square feet.
Hope this helped :)
1) 3/4-1/4=2/4=1/2
2)3/10-1/10=2/10=1/5
Answer:
x= 1/22 and y=-1/4 (I'm assuming that the equal signs are the only separators of the equation sequence, since there is no indicator that the so-called "sentences" are actually apart.
