wrote this expression on the board: 2 12 ÷ 34 She asked her students to write a word problem that could be solved using the expression she wrote on the board. Which word problem could be solved using the expression?
Step-by-step explanation:
The equation equation looks incomplete. However assuming it to be 212÷34.
This becomes a simple case of division. Now forming a world problem on this equation.
Consider there are 212 chocolates to be distributed among 34 children, such that each child gets equal number of chocolates. Find how many chocolate does each child got.
Simply divide 212 by 34 to get the answer =212/34

Subtract equation two 3 digit numbers with different hundreds digits and a difference of less than 100
Answer:
690 - 595
Step-by-step explanation:
As we know that representation of a 3 digit number = xyz
where x [tex]\neq[/tex] 0
z is at ones place
y is at tens place
x is at hundred place
As, we have to subtract two 3 digits numbers with different hundred digits
So, Let
The hundred digit of first number be 6
The hundred digit of second number be 5
∴
Assume first number with hundred digit 6
Let the number be - 690
Now,
Assume second number with hundred digit 5
Let the number be - 595
Now,
We will check that the difference between both the numbers are less than 100 or not
Now,
690 - 595 = 95 < 100
It satisfies the condition
So, the equation becomes 690 - 595

Simplify (2x - 6)2
????
Answer:
4x-12
Step-by-step explanation:
just distribute the 2 over to the 2x and the -6. That means multiply 2, to everything in the parentheses. Hope that's helpful
The simplified form of the expression [tex](2x - 6)^2[/tex] is [tex]4x^2 - 24x + 36.[/tex]
To simplify the expression[tex](2x - 6)^2[/tex] expand the square.
The square of a binomial follows the formula:
[tex](a - b)^2 = a^2 - 2ab + b^2.[/tex]
The binomial is 2x - 6.
Applying the formula, we have:
[tex](2x - 6)^2 = (2x)^2 - 2(2x)(6) + (-6)^2[/tex]
Simplify each term:
[tex](2x)^2 = 4x^2[/tex]
[tex]2(2x)(6) = 24x[/tex]
[tex](-6)^2 = 36[/tex]
Substituting these simplified terms back into the expression:
[tex](2x - 6)^2 = 4x^2 - 24x + 36[/tex]
Therefore, the simplified form of [tex](2x - 6)^2[/tex] is [tex]4x^2 - 24x + 36.[/tex]

A is directly proportional to B squared
When A= 500, B = 10.
Find A when B= 20.
Answer:
A = 2000.
Step-by-step explanation:
A = kB^2 where k is a constant to be found, so substituting:
500 = k * 10^2
100k = 500
k = 5.
So we have
A = 5B^2
When B = 20:
A = 5 * 20^2
= 5 * 400
= 2000.

Point (7,12) is rotated 1260° counterclockwise about the origin. What is the X-coordinate of the point after this rotation?
Given:
Point (7,12) is rotated 1260° counterclockwise about the origin.
To find:
The x-coordinate of the point after this rotation.
Solution:
If a point is rotated 360 degrees then its coordinates remains unchanged.
If a point is rotated 180 counterclockwise about the origin degrees, then
[tex](x,y)\to (-x,-y)[/tex]
We know that,
[tex]1260^\circ=1080^\circ+180^\circ[/tex]
[tex]1260^\circ=3\times 360^\circ+180^\circ[/tex]
After [tex]3\times 360^\circ[/tex] rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.
[tex](7,12)\to (-7,-12)[/tex]
The point (7,12) becomes (-7,-12) after rotation of 1260° counterclockwise about the origin.
Therefore, the x-coordinate of the required point is -7.
