Answer:

3)5x-4y=-3

6x+4y=14

Step-by-step explanation:

The system of equations is given

5x-4y=-3

3x+2y=7

Multiplying both sides of the lower equation by 2, we get

6x + 4y = 14

That means your answer 3)

If x = 45, y = 63, and the measure of AC = 4 units, what is the difference in length between segments AB and AD? Round your answ

brilliants [131]

Answer:

1.17 units

Step-by-step explanation:

From the definition of the sine of an angle, you know ...

sin(45°) = AC/AB = 4/AB ⇒ AB = 4/sin(45°) ≈ 5.6569

sin(63°) = AC/AD = 4/AD ⇒ AD = 4/sin(63°) ≈ 4.4893

Then the difference AB-AD is ...

AB -AD = 5.6569 -4.4893 = 1.1676

AB -AD ≈ 1.17 units

Find m<SPT in degrees

koban [17]

Answer: 60°

<u>Step-by-step explanation:</u>

∠UQR = 180°

∠UQR = ∠UQ + ∠QR

180° = 115° + ∠QR

65° = ∠QR

∠QRT = 180°

∠QRT = ∠QR + ∠RS + ∠ST

180° = 65° + ∠RS + 55°

180° = 120° + ∠RS

60° = ∠RS
