Answer 1

associative

Answer 2

evaluate the expression 3b-ac when a=-2, b=3, and c=0.5

Answer 3

When a = -2, b = 3, and c = 0.5, we can substitute these values into the expression 3b - ac:

3b - ac = 3(3) - (-2)(0.5)
= 9 + 1
= 10

Therefore, when a = -2, b = 3, and c = 0.5, the value of the expression 3b - ac is 10.

Answer 4

evaluate the expression 5x^2+2y when x=-3 and y =0.25

Answer 5

When x = -3 and y = 0.25, we can substitute these values into the expression 5x^2 + 2y:

5x^2 + 2y = 5(-3)^2 + 2(0.25)
= 5(9) + 0.5
= 45 + 0.5
= 45.5

Therefore, when x = -3 and y = 0.25, the value of the expression 5x^2 + 2y is 45.5.

Answer 6

evaluate the expression 3mn/-2p when m=1/3, n=-3, and p=3

Answer 7

When m = 1/3, n = -3, and p = 3, we can substitute these values into the expression 3mn/-2p:

3mn/-2p = 3(1/3)(-3)/(-2)(3)
= 1(-3)/(-2)(3)
= -3/(-6)
= 1/2

Therefore, when m = 1/3, n = -3, and p = 3, the value of the expression 3mn/-2p is 1/2.

Answer 8

which expression is equivalent to: (3xy-2xz+yz)+(2xy-4xz-5yz

Answer 9

To simplify the given expression, we can combine like terms:

(3xy - 2xz + yz) + (2xy - 4xz - 5yz)

Combining like terms:
3xy + 2xy - 2xz - 4xz + yz - 5yz

Rearranging the terms:
(3xy + 2xy) + (-2xz - 4xz) + (yz - 5yz)

Simplifying further:
5xy - 6xz - 4yz

Therefore, the expression that is equivalent to (3xy - 2xz + yz) + (2xy - 4xz - 5yz) is 5xy - 6xz - 4yz.

Answer 10

which expression is equivalent to: 5x^2 +3x-2x^2+4x

Answer 11

To simplify the given expression, we can combine like terms:

5x^2 + 3x - 2x^2 + 4x

Combining like terms:
(5x^2 - 2x^2) + 3x + 4x

Simplifying further:
3x^2 + 7x

Therefore, the expression that is equivalent to 5x^2 + 3x - 2x^2 + 4x is 3x^2 + 7x.

Answer 12

which expression is equivalent to: -3(2x+5)+7

Answer 13

To simplify the given expression, we can use the distributive property:

-3(2x + 5) + 7

-3 * 2x + (-3) * 5 + 7

-6x - 15 + 7

-6x - 8

Therefore, the expression that is equivalent to -3(2x + 5) + 7 is -6x - 8.

Answer 14

simplify 12(x+4)

Answer 15

To simplify 12(x + 4), we use the distributive property:

12(x + 4) = 12 * x + 12 * 4

Simplifying further:

12x + 48

Therefore, the simplified form of 12(x + 4) is 12x + 48.

Answer 16

simplify -2(2x-5)

Answer 17

To simplify -2(2x - 5), we can use the distributive property:

-2(2x - 5) = -2 * 2x + (-2) * (-5)

Simplifying further:

-4x + 10

Therefore, the simplified form of -2(2x - 5) is -4x + 10.

Answer 18

simplify 1/2(6x+10)

Answer 19

To simplify 1/2(6x + 10), we can use the distributive property:

1/2(6x + 10) = (1/2) * 6x + (1/2) * 10

Simplifying further:

3x + 5

Therefore, the simplified form of 1/2(6x + 10) is 3x + 5.

Answer 20

simplify 3(8-5x)+2x

Answer 21

To simplify 3(8 - 5x) + 2x, we can use the distributive property:

3(8 - 5x) + 2x = 3 * 8 - 3 * 5x + 2x

Simplifying further:

24 - 15x + 2x

Combining like terms:

-13x + 24

Therefore, the simplified form of 3(8 - 5x) + 2x is -13x + 24.

Answer 22

simplify 5x-4(2+3x)

Answer 23

To simplify 5x - 4(2 + 3x), we can use the distributive property:

5x - 4(2 + 3x) = 5x - (4 * 2) - (4 * 3x)

Simplifying further:

5x - 8 - 12x

Combining like terms:

-7x - 8

Therefore, the simplified form of 5x - 4(2 + 3x) is -7x - 8.

Answer 24

is -7+9=-9+7 true false or open

Answer 25

The expression -7 + 9 = -9 + 7 is true.

Answer 26

is 4x-3=19 true false or open

Answer 27

To determine if the equation 4x - 3 = 19 is true, we need to solve it:

4x - 3 = 19

Adding 3 to both sides:

4x = 22

Dividing both sides by 4:

x = 5.5

The equation is true when x = 5.5. Therefore, the statement 4x - 3 = 19 is false.

Answer 28

slove 16=4x-4

Answer 29

To solve the equation 16 = 4x - 4, we need to isolate the variable x.

Adding 4 to both sides:

16 + 4 = 4x - 4 + 4
20 = 4x

Dividing both sides by 4:

20/4 = 4x/4
5 = x

Therefore, the solution to the equation 16 = 4x - 4 is x = 5.
