Name the property that is illustrated by the statement below: 2 + 7 + 3 = 2 + 7 + 3
The property illustrated by the statement is the commutative property of addition.
Evaluate the expression 3b−ac when a = −2, b =3, and c=0.5.
To evaluate the expression 3b−ac, we substitute the given values of a, b, and c into the expression.
Substituting a = -2, b = 3, and c = 0.5, we get:
3(3) - (-2)(0.5)
Simplifying the expression:
9 + 1
Final answer:
10
Evaluate the expression 5x2+2y when x = −3 and y =0.25.
To evaluate the expression 5x^2+2y, we substitute the given values of x and y into the expression.
Substituting x = -3 and y = 0.25, we get:
5(-3)^2 + 2(0.25)
Simplifying the expression:
5(9) + 0.5
45 + 0.5
Final answer:
45.5
Evaluate the expression 3mn −2p when m = 1 3, n =−3,and p=3.
To evaluate the expression 3mn - 2p, we substitute the given values of m, n, and p into the expression.
Substituting m = 1/3, n = -3, and p = 3, we get:
3(1/3)(-3) - 2(3)
Simplifying the expression:
-3 - 6
Final answer:
-9
Which expression is equivalent to 3xy − 2xz + yz + 2xy − 4xz − 5yz?
To simplify the given expression, we group the like terms together:
(3xy + 2xy) + (-2xz - 4xz) + (yz - 5yz)
Simplifying each group:
5xy - 6xz - 4yz
The expression that is equivalent to 3xy − 2xz + yz + 2xy − 4xz − 5yz is 5xy - 6xz - 4yz.
