What is the expression for x equals 3 and y equals 6?
A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.
What is 2x 5?
-3
What is the value of the expression x-y squared when x equals 7 and y equals negative 2?
If the expression is (x - y)2, the solution is (7 - -2)2 = (7+2)2 = 92 = 81. If the expression is x - y2, the solution is 7 - (-2)2 = 7 - 4 = 3.
How do evaluate the expression x to the second power plus 3x for x 1.7?
The idea is to replace "x" by "1.7" in this case, then do all the indicated calculations.
Substitute 4 for x and evaluate the expression 3x - 5 - 10?
3x actually means 3 * x.So we are going to follow BODMAS rule... 3x-5-10 =3*4-5-10 =12-5-10 =7-10 =-3 Here's your answer..
Evaluate the variable expression for x equals 3?
Take 3 and substitute into the expression given to you but not mentioned in the question here and evaluate the expression. "Sub and Solve" I say.
How do you evaluate expression 0.2 x n for n equals 3 and n equals 6?
3 6
Evaluate this expression for these numbers abc a equals 2 b equals 4 c equals 3?
2*3*4 = 24
How do you Evaluate the expression 7d-5c if d equals 7 and c equals 3?
(7 x 7) - (5 x 3)
Evaluate the expression for the given value of the variable 5y - 1 for y equals 3?

What does evaluate 7a means?
"Evaluate 7a" typically means to calculate the value of the expression by substituting a specific value for the variable "a." For example, if "a" is given as 3, you would substitute it into the expression to get 7 * 3, which equals 21. If no value for "a" is provided, the expression remains as 7a.
How would you evaluate 15k when k equals 3?
To evaluate 15k when k equals 3, you would substitute the value of k into the expression. Therefore, 15k becomes 15(3), which simplifies to 45. So, when k equals 3, 15k equals 45.
Evaluate the expression for a 4 and b 3.?
Unfortunately there is no expression to evaluate!
What Evaluate this exponential expression?
To evaluate an exponential expression, you need to substitute the values into the expression and perform the necessary calculations. For instance, if the expression is (2^3), you would calculate it as (2 \times 2 \times 2), which equals 8. If you provide a specific exponential expression, I can help with the evaluation.
What expression is 9c - 3 when c 10?
To evaluate the expression (9c - 3) when (c = 10), substitute 10 for (c): [9(10) - 3 = 90 - 3 = 87.] So, when (c = 10), the expression (9c - 3) equals 87.
What is the degree of the polynomial -2xy3 plus 3x2y?
I will assume that you mean -2xy3+3x2y. Then by "degree" is usually meant the total degree--the maximum sum of exponents of all variables. Here the first term has degree 1+3=4 and the second term has degree 2+1=3, so the degree of the entire expression is 4. It is also a 2nd degree expression in x and a 3rd degree expression in y.
What is the value of 3xy plus 4y3 and y equals 2 the expression below when x equals 5?
To evaluate the expression (3xy + 4y^3) when (y = 2) and (x = 5), substitute the values into the expression. This gives: [ 3(5)(2) + 4(2^3) = 30 + 4(8) = 30 + 32 = 62. ] Thus, the value of the expression is 62.
