Step-by-step explanation:
base b = 11 cm
Height h = 6 cm
= 11 * 3
= 33 cm²
Answer:
12.42 -(-4.8) = 17.22
Step-by-step explanation:
1. The most important thing to note is the double negative signs, separated by the paranthesis. When 2 signs, numbers, variable, etc... are separated by a ( ) or simply beside each other, such as 2x or 4(6), you would multiply the 2 numbers.
2. In this equation, note that the negative sign is directly beside the (4.8):
(-)(-4.8) This means that you would multiply the negative sign or -1 by the -4,8. Remember multiplication rules with signs: a negative (-) number x a negative (-) number = a POSITIVE number.
3. Therefore, (-)(-4.8) is looking at the problem as (-) x (-4.8) = +4.8.
4. Note that at this point, the equation becomes an addition problem:
12.42 + 4.8 = x
5. Use your calculator to solve or the CORRECT way of simply lining up the decimals, and, there's your answer:
12.42 + 4.8 = 17.22
Answer:
the solution of the equation is:
Step-by-step explanation:
we are given the expression as
=
we will use the number line rule for inequalities(first by making the coefficients of x positive then taking the roots on the number line and depending on the sign in the equation we start taking alternate signs and depending on the inequality take the desired region)
we get .
Answer:
Nicholas pulls 5 blue marbles from the bag.
Step-by-step explanation:
Since Nicholas performs an experiment in which he pulls a marble from a bag, and in his experiment, he finds that he is twice as likely to pull a red marble as a blue marble, to determine, if Nicholas pulls 10 red marbles, how many blue marbles does he pull, the following calculation must be performed:
10/2 = X
5 = X
Therefore, Nicholas pulls 5 blue marbles from the bag.
