3/12x5 is the answer of your question.
To find 3x + 42 = 21, you have to subtract 42 from both sides of the equation.
3x + 42 - 42 = 21 - 42
3x = -21
Now, you have to divide 3 from both sides to get your desired answer.
= ![\frac{-21}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-21%7D%7B3%7D)
x = -7
The final answer is -7.
Answer:
117π or 367.56634047
Step-by-step explanation:
Volume = π × r² × h (r=radius and h=height)
Volume = π × 4² × 13
Volume = π × 9 × 13
Volume = π × 117
Volume = 117π
The correct answer is 110 cm
Explanation:
Fractions always include two values (one at the top and the other at the bottom) and they represent the proportion of something, for example, 1/2 of an apple means there is only half apple. Now, to calculate how much is 5/7 of 154 centimeters, simply divide the total number into the denominator (bottom number) and then multiply the result by the numerator (top number). This process is shown in detail below:
- 5 is the numerator and 7 is the denominator
5/7 of 154 cm
154 cm / 7 = 22
22 x 5 = 110 cm
