What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the two numbers are 1.6 and 0.215. The solution of the numbers will be,
P = 1.6 x 0.215
P = 0.344
Therefore, the solution of the product of the two numbers 1.6 and 0.215 will be 0.344.

His mistake is that he does not open the bracket first. The value of the x is negative of 4.
What is a BODMAS rule?BODMAS rule means for the Bracket, Order, Division, Multiplication, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Andre tried to solve the equation 1/4 ( x + 12 ) = 2.
First, open the bracket, then we have
[tex]\dfrac{x}{4} + \dfrac{12}{4} = 2[/tex]
On simplifying, we have
[tex]\dfrac{x}{4 } + 3 = 2[/tex]
Subtract 3 from both sides, we have
[tex]\dfrac{x}{4} = -1[/tex]
Multiply the equation by 4, we have
[tex]x = -4[/tex]

A box contains 6 red marbles, 4 green marbles, 3 blue marbles, and 2 yellow marbles. If Greg chooses one marble at random 300 times, how many times would he expect the marble to be blue?
Answers
Answer:
[tex]60[/tex] times
Step-by-step explanation:
There are [tex]6+4+3+2=15[/tex] marbles in total. Out of those, [tex]3[/tex] are blue, so the probability of pulling a blue marble is [tex]\frac{3}{15}=\frac{1}{5}[/tex]. However, this is only the probability of pulling a blue marble when [tex]1[/tex] marble is pulled at random. Therefore, we can expect a blue marble to be pulled [tex]\frac{1}{5}*300=60[/tex] times if [tex]1[/tex] marble is pulled [tex]300[/tex] times at random. Hope this helps!

A supermarket marks down the price of a $3.00 loaf of bread by 20%. What is the discount and the new price of the loaf of bread?
Answers
Answer:
new price= $2.40
Step-by-step explanation:
20%= 20/100= 1/5
$3.00/5= 00.60
1/5 of the price is being subtracted from $3.00
$00.60 is 1/5
3.00-.60= 2.40
Answer:
The discount is 20% off (you only have to pay 80% of the original price)
The new price of the bread is $2.40 (60 cents off)
Step-by-step explanation:
Because 20 goes into 100, 5 times I did 3.00/5
3.00/5= 0.6
Subtract 0.60 from the 3 dollars and that's it!
3.00-0.60= 2.40
