Andre tried to solve the equation 1/4 ( x + 12 ) = 2. What was his mistake? Explain.
1/4x = -10
x = -40
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]

Rewrite 4x9 as addition.
Answer:
9+9+9+9
or
4+4+4+4+4+4+4+4+4
Picture Attached: 9 + 9 + 9 + 9 = 36 or 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 = 36
To find 4x9 we can stack and align the numbers by place value columns!
- Put the 6 in Ones place
- Carry the 3 to Tens place
- Answer 36!
Long addition is a process for adding numbers together:
- Stack your numbers and align the columns by place value.
- Add all numbers column by column from right to left.
- Record the sum in the answer space for each column.
- If the sum of any one column is greater than nine, carry the additional digits to the next highest column.

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?
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?
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

Answer:
0.3440
Step-by-step explanation:
16 *0.215 = 80 = 160 = 32
80+160+32 = 3440
The solution of the product of the two numbers 1.6 and 0.215 will be 0.344.
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.
