Option B:
Solution:
Take LCM of the denominators and Make the denominators same.
LCM of 16, 320, 1 = 320
All the denominators are same, so you can write in one fraction.
Do cross multiplication.
Add 9280 on both sides of the equation.
Subtract 20x on both sides of the equation.
Let y = f(x).
Hence Option B is the correct answer.
Answer:
x= 13
Step-by-step explanation:
−4/9(18x − 36) = −88
we need to solve the equation for x
First we remove the fraction -4/9
Multiply by -9/4 on both sides
18x -36 = 198
Now add 36 on both sides
18x = 234
Divide both sides by 18
x = 13
Answer:
n ≤ 4
Step-by-step explanation:
"The difference between a number and seven is less than or equal to -3" translates into n - 7 ≤ -3. To solve, isolate the variable n.
n - 7 ≤ -3
n ≤ -3 + 7
n ≤ 4
The best estimate would be D: 331 km
To find the volume of a box that would hold these nine cylinders, you would start with the formula for volume of a cylinder. V=pi x r^2 x h. Substitute in the known volume and the known Height. 9.425=pi x r^2 x 3. Divide both sides by three to get approximately 3.143 = pi x r^2. Divided by pi on both sides. This leaves you with one = r^2. So the radius is equal to one. If the radius equals one, the diameter is two. Assuming the cylinders are arranged in a 3 x 3 array, the length and width of the rectangle or box would be 6cm x 6cm. To find the volume of the box necessary, multiply the length of six by the width of six by the height of three. The volume would be 108 square cm.
