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?

Evaluate the expression for a 4 and b 3.?
Unfortunately there is no expression to evaluate!
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.
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.
What does it mean by evaluate the expression when n equals 7 and when n equals 0.4?
To evaluate the expression when ( n ) equals a specific value, you substitute that value into the expression in place of ( n ). For example, if the expression is ( f(n) = n^2 + 3n ), you would calculate ( f(7) ) by substituting 7 for ( n ), resulting in ( 7^2 + 3(7) ). Similarly, for ( n = 0.4 ), you would substitute 0.4 into the expression and compute the result. This process allows you to find the numerical value of the expression for those specific values of ( n ).
