Answer 1

Answer:

2y + 12

Step-by-step explanation:

Combine like terms. The terms are numbers with a y, & then numbers without.

So combine the y's, leave the 12.

5y - 3y + 12

5 - 3 = 2

2y + 12

Hope this helps. :0)

James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply. 7 x + 4 and 3 x + 5 + 4 x minus 1 When x = 2, both expressions have a value of 18. The expressions are only equivalent for x = 4 and x = 6. The expressions are only equivalent when evaluated with even values. The expressions have equivalent values for any value of x. The expressions should have been evaluated with one odd value and one even value. When x = 0, the first expression has a value of 4 and the second expression has a value of 5. The expressions have equivalent values if x = 8.

Step-by-step explanation:

On monday, your bank account balance was -$12.58. Because you didn't realize this, you wrote a check for $30.72 for groceries. a) What is the new balance in your checking account? b) The bank charges a $25 fee for playing a check on a negative balance. What is the balance in your checking account after this fee? c) How much money do you need to deposit to bring your account balance back up to $0 after the fee?

Answers

Answer:

a) The new balance in your checking account is -$12.58 - $30.72 = -$43.30.

b) After the bank charges a $25 fee for overdrafting, the balance in your checking account will be -$43.30 - $25 = -$68.30.

c) To bring your account balance back up to $0 after the fee, you will need to deposit $68.30.

Step-by-step explanation:

Answer:

First, you subtract the 30.72 from the -12.58 which is -43.03 which is therefore how much you have in your account. Then we subtract another 25 for the fee. -68.03 Is how much you have after paying the fee.

Therefore, to get to 0, you need to pay 68 dollars and 3 cents.

Two lines meet at a point that is also the vertex of an angle. Set up and solve an appropriate equation for and .

Answers

Answer:

Y=74, x=106.

Step-by-step explanation:

First, if you will notice, that 16+Y=90. Why? Because there is a square instead of a semicircle at the angle, which means that 16+Y=90. 90-16=74, so Y is 74. Then, we see that 90 plus an unknown angle equals x. But, using a rule of geometry, we know that the unknown angle is 16. So, x=90+16, and since 90+16 is 106, we get Y=74, X=106.
