The answer is 2.7
I’m not an expert at this but i did some research so I hope I can help
It’s 2.7 because the formula for calculating density is to divide the mass by the volume and in you do that for each of them you get 2.7 every time
3=4m+ b
-1=3m+b
m=4
plug in to either equation,
3=16+ b
b=-13
Thus, C would be the answer.
Answer:
Step-by-step explanation:
<u>Use the Pythagorean theorem:</u>
<u>Verify this for each line:</u>
1.
- 28² + 45² = 53²
- 2809 = 2809
- Yes
2.
- 33² + 56² = 64²
- 4225 ≠ 4096
- No
3.
- 36² + 77² = 85²
- 7225 = 7225
- Yes
First, find a lowest common denominator. The lcd in this equation os 8 so your new fractions would be 4/8, 6/8, and 7/8. You add the numerators (top numbers), which equals 17/8. Then you simplify to 2 1/8 liters.
Answer:
x = -2
Step-by-step explanation:
3(-2 - 3x) = -9x - 4 (Given)
3(-2) + 3(-3x) = -9x - 4 (Distributive Property of Equality)
-6 + 9x = -9x - 4 (Simplify)
-6 + 4 -9x= -9x - 4 + 4 (Addition Property of Equality)
-2 + 9x = -9x (Simplify)
-2 + 
(Division Property of Equality)
-2 = x (Simplify)
x = -2 (Symmetric Property of Equality)
