Answer:
-4.3, -3.4, -0.43, -0.34, -0.043
Answer:
i dont really know the answer
Step-by-step explanation:
Number of surface = 5
Surface 1: 8 x 5 = 40 . [The left side]
Surface 2: 15 x 5 = 75 . [The bottom side]
Surface 3: 17 x 5 = 85 . [The slanted side]
[Surface 4 and 5 are triangles and they have the same surface area]
Surface 4 : 1/2 x 15 x 8 = 60
Surface 5 : 60
Total : 40 + 75 + 85 + 60 + 60 = 320 square units
You are correct for the first part, you would be 16 and your Mom would be 44. After 8 years, you would be 24 and your mother would be 52. You solve the second part by adding 8 to 16 which equals 24. Then multiply 24 times 3 which equals 72. Lastly, subtract 20 from 72 to find your mother's new age. Which would be 52.
Hope this helps !
Answer:
x = -8
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
-1x = -8 - 2x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Simplify: -x = -8 - 2x
- Add 2x on both sides: x = -8
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: -1(-8) = -8 - 2(-8)
- Multiply: 8 = -8 + 16
- Add: 8 = 8
