Answer: x = 94.5
Explanation: By using PEMDAS you can see there is no parentheses, exponents, or multiplication, so you start with dividing.
You can go ahead and combine the two x’s so you have 2x. So our equation now looks like:
2x + 2 ÷ 4 = 189
Divide first.
2 ÷ 4 = .5
Subtract from both sides.
.5 - 189.5 = 189
Divide by two to isolate the variable.
2x ÷ 189 = 94.5
so X =94.5
check your answer by plugging in the final number.
94.5 + 94.5 + 2 ÷ 4 = 189.5
Answer: 9 inches
Step-by-step explanation:
Let x be the longest side of the acute triangle having other sides 5 inches and 8 inches,
Since, for the acute triangle,
![(\text{longest side})^2< \text{ sum of the square of the other sides}](https://tex.z-dn.net/?f=%28%5Ctext%7Blongest%20side%7D%29%5E2%3C%20%5Ctext%7B%20sum%20of%20the%20square%20of%20the%20other%20sides%7D)
![\implies x^2 < 5^2 + 8^2](https://tex.z-dn.net/?f=%5Cimplies%20x%5E2%20%3C%205%5E2%20%2B%208%5E2)
![\implies x^2< 25 + 64](https://tex.z-dn.net/?f=%5Cimplies%20x%5E2%3C%2025%20%2B%2064)
![\implies x^2 < 89](https://tex.z-dn.net/?f=%5Cimplies%20x%5E2%20%3C%2089)
![\implies x < 9.43398113\approx 9.434](https://tex.z-dn.net/?f=%5Cimplies%20x%20%3C%209.43398113%5Capprox%209.434)
Thus, the largest value of x ( whole number ) is 9.
Answer:
2.4
Step-by-step explanation:
Add -3.6 and 2 inside the bracket. Then multiply the result by -1.5.
![-3.6 + 2 = -1.6\\-1.5(-1.6) = 2.4](https://tex.z-dn.net/?f=-3.6%20%2B%202%20%3D%20-1.6%5C%5C-1.5%28-1.6%29%20%3D%202.4)
Note: Two negatives make a positive.
The answer is B) Exponentially, shows a constant percentage in sales per month
