4 hours is 8 half hours
8*2 is 16 so the answer is d
Hope this helps :)
Answer:
Yes, they are congruent
Step-by-step explanation:
Two figures are congruent if they have the same side lengths and the same angles, all in the same order. (I mean "same order" by you couldn't have a rectangle and a kite with different orders of the sides being congruent). Now, if we use this, we can compare the sides and angles to find out that they are indeed congruent.
You could make them have the same denominator, making it 7/10-5/10=2/10.
The answer is 2/10, or simplified, 1/5.
16 - 12x = 4y
First, divide both sides by 4. / Your problem should look like: \frac{16-12x}{4} = y
Second, factor out the common term 4. / Your problem should look like: \frac{4(4-3x)}{4} = y
Third, cancel 4. / Your problem should look like: 4 - 3x = y
Fourth, switch sides. / Your problem should look like: y = 4 - 3x
Answer: y = 4 - 3x
Answer:
aₙ = 4(-1)ⁿ⁻¹(3)ⁿ⁻¹
Step-by-step explanation:
The formula for the nth term of a geometric sequence is
aₙ = a₁rⁿ⁻¹
We can get the value for r by dividing aₙ by aₙ₋₁.
a₄/a₃ = -108/36
a₄/a₃ = -3
r = -3
aₙ = 4(-3)ⁿ⁻¹
aₙ = 4(-1)ⁿ⁻¹(3)ⁿ⁻¹
The (-1)ⁿ⁻¹ term makes even-numbered terms negative.
