Answer:

  • -6y + 4

Step-by-step Solution:

  • -2x - 4y + 10 + 2x - 2y - 6
  • => (-2x + 2x) + (-4y - 2y) + (10 - 6)
  • => (-6y) + (4)
  • => -6y + 4

Hence, the simplified result is -6y + 4.

Ryan's tennis club membership, which is $11, is deducted automatically from his bank account every month. Which expression shows
Solnce55 [7]
(-$11) x 12. That would be the equation because there are 12 months, so you would multiply -11 from 12 to get -132 every year for the tennis club membership.

State the property that justifies the statement: If 4x + 9 = 15 and X=2y + 1,
GREYUIT [131]

Answer:

Substitution property of equality

Step-by-step explanation:

Given

4x + 9 = 15 and x = 2y + 1

Then

4(2y + 1) + 9 = 15

Required

State the property

From the list of options, (d) answers the question.

This is so because:

Substitution property of equality states that

If a = b then b = a

In other words, both can replace one another.

So if x = 2y + 1, then 2y + 1 can be substituted for x in 4x + 9 = 15

So:

4x + 9 = 15  becomes

4(2y + 1) + 9 = 15

<em>Hence, it is substitution property of equality</em>

The sum of two numbers is 30. the first number is twice the second number. what are the numbers?
Fudgin [204]
Let the numbers be x and y.

by the first statement of the question, we get , x + y = 30.,,..(1)

by the second satement, we get , x = y+ y => x=2y... (2)

from equation (2), let us put the value of x in equation (1),
x + y = 30
=> 2y + y = 30
=> 3y = 30
=> y =30/3
=> y = 10

and x=2y => x = 2*10 = 20

in short, the numbers are 10 and 20
