  • x = 13.5
  • y = 3.5

Step-by-step explanation:

  • Solving for x

7x + 30 = 11x - 24

30 + 24 = 11 - 7x

54 = 4x

54/4 = x

27/2 = x

<u>13.5 = </u><u>x</u>

  • Solving for y

5y + 38 = 17y - 4

38 + 4 = 17y - 5y

42 = 12y

42/12 = y

21/6 = y

7/2 = y

<u>3.5 = y</u>

QveST [7]

Answer:

x = 0.954

Step-by-step explanation:

We apply pythagorean to find x

(4-x)² = 1.2² + 2.8²

(4-x)² = 9.28

✓(4-x)² = ✓(9.28)²

4 - x = 3.046

- x = 3.046 - 4

- x = -0.954

x = 0.954

Help pls!!! The radius of a circle is 15 inches. Enter the area of the circle, in square inches. Round your answer to the neares
Bas_tet [7]

Answer:

706.5 inches squared

Step-by-step explanation:

The formula for the area of a circle is pi r^2. r being the radius. Because you have the radius, and pi is 3.14 in this case, your new formula is A=3.14(15)^2. 15 squared is 225, times 3.14 gives you 706.5

Your final answer is already in tenths so you don't need to round! Hope this helps :)) and brainliest is always appreciated
