First, write a statement to define your unknown variable. This is technically not essential to solving the problem, but many teachers prefer to see it.
Example: Let w = the manatee's weight in pounds.
Next, decide what the variable needs to be multiplied by. 12% is equal to 0.12. Usually when a problem says "of," it wants you to multiply. Therefore, 12% of the body weight equals 0.12w. Since the problem already says that this is how much the manatee eats every day, that is your answer.
y = 0.12w
Answer:
<em>n </em>+ 17 = 26
Step-by-step explanation:
<u>Let's replace the sentence with mathematical terms:</u>
17 more than a number is 26
More than means addition. The answer will also be a sum.
17 + a number is 26
Since the number is not specified, it will be represented by a variable. In this instance, the variable is <em>n</em>.
17 + <em>n</em> is 26
The equal sign will replace the word "is".
17 + <em>n</em> = 26
<u>Now, we can use the associative property of addition.</u>
17 + <em>n</em> = 26 into <em>n </em>+ 17 = 26
Answer:
x² + x - 12 = 0
Step-by-step explanation:
If x = -4 and x = 3 are solutions to a quadratic equation, then
(x + 4)(x - 3) = 0
Expand the brackets: x² - 3x + 4x - 12 = 0
Combine like terms: x² + x - 12 = 0
Answer:
Look DB
Step-by-step explanation:
Since the 1+2=180, m<1=21
Using the angles rule, m<4=159, and m<3=21
