What is the algebraic expression for 3 more than a number?
The algebraic expression for "3 more than a number" can be written as x + 3, where x represents the unknown number. In this expression, the variable x is being increased by 3. This expression can be simplified further if needed, but the basic form is x + 3.
Oh, dude, that's like basic math. So, if you have x minus 7 equals 8, you just add 7 to both sides to get x equals 15. Easy peasy lemon squeezy. Math, man, it's like magic but with numbers.
3x times 2y = 3x2y
In a system of equations, you can only solve for a system if there are the same amount of variables as equations. Since there is only one equation (actually, it is a monomial, but considering 3x2y=0) and there are two variables, x and y, we cannot solve for the variables. The simplest form is 3x2y.
How do you write 420 in standard form?
4.2 x 10 with a little 2 next to the ten.
i did this because in standard form , the decimal needs to be below 10 so i reduced it to 4.2. it then needs to be timesed by 10 twice in order to return it to 420.
Yes. To convert from yards to feed, you need to multiply by 3.
What is the perimeter of a square that is 72 centimeters?
72 centimeters of what.
im gonna assume the area is 72 cm. so it would be 72 sq cm
your perimeter would be around 33.94
you need to take the squared root of 72. this gives the length of one side. then multiply this number by 4 since there are four sides to a square.
How many feet are in 16 decimals?

What is a symmetrical numbers?
Oh, dude, symmetrical numbers are like those cool numbers that read the same forwards and backwards, you know, like 121 or 1331. It's like math's way of playing with mirrors, making numbers all balanced and stuff. So, yeah, symmetrical numbers are basically the numbers that are too cool to only be read in one direction.
How do you separate 17 Greek goats by drawing six straight lines?
Oh, dude, separating goats now, are we? Well, you can totally do that by drawing six straight lines in a way that creates separate pens for the goats. Just make sure the lines intersect in a way that forms distinct areas for the goats to chill in. It's like a goat maze, but with lines instead of walls.
How Long is each side of the triangle if the perimeter is 234 cm?
If the perimeter of a triangle is 234 cm, then the sum of the lengths of all three sides is 234 cm. Since a triangle has three sides, each side would be one-third of the perimeter. Therefore, each side of the triangle would be 234 cm divided by 3, which equals 78 cm.
To calculate 44 x 99, you can use the method of multiplication by breaking down the numbers into their components. You can break down 44 as 40 + 4 and 99 as 90 + 9. Then, multiply each component of 44 by each component of 99 and add the results together. This gives you (40 x 90) + (40 x 9) + (4 x 90) + (4 x 9), which simplifies to 3600 + 360 + 360 + 36, resulting in 4356.
