5 0

Answer:

a = 3

b= -1  

c = 5

X = (-b +- sqrt [b^2 - 4ac]) / 2a

X = (--1 +- sqrt (1 - 4*3 * 5)) / 2* 3

x = (1 += sqrt (1 -60)) / 6

x1 = (1 + sqrt (-59)) / 6

x2 = (1 - sqrt (-59)) / 6

Find the perimeter of the triangle.​
IRISSAK [1]

Answer:

39

Step-by-step explanation:

Alll the sides equal each other because of that curve u see at each angle, that curve means that the angles are the same, having the same angles means same sides, so just pick two equations to do this:

21 - x = 2x -3

add 3 to both sides

24 - x = 2x

add x to both sides

24 = 3x

divide by 3

8 = x

Now input 7 into the equations:

21 - x = 21 - 8 = 13

2(8) - 3 = 16 - 3 = 13

x + 5 = 8 + 5 = 13

Now add: 13 + 13 + 13 = 26 + 13 = 39

Another way for u to save time is remember how i said all the sides were the same? you could just solve one equation, so it'll be 13 and multiply that with 3 to get the perimeter since ur adding 13 three times anyway

So just a simple: 13(3) = 39

Clarisa's annual gross pay as an account manager is $54,000. If the graduated state tax rate is 1% for the first $5,000 and 3% f
Hoochie [10]

Answer:

Total taxes = $1,520

Step-by-step explanation:

We have two separate calculations for the taxes:

The tax rate for the first $5,000 of Clarisa's gross pay is 1%, so the amount of tax paid in this case is

1% * 5000 = $50

The tax rate for the amount of value over $5,000 (that is, 54,000 - 5,000 = 49,000) is 3%, so the amount of tax is:

3% * 49,000 = $1,470

So, the total amount deducted for state taxes is:

Total taxes = 50 + 1470 = $1,520

How do I solve -15= -3n/5
xenn [34]

Answer:

<h2>n = 25</h2>

Step-by-step explanation:

-\dfrac{3n}{5}=-15\qquad\text{multiply both sides by (-5)}\\\\(-5\!\!\!\!\diagup^1)\left(-\dfrac{3n}{5\!\!\!\!\diagup_1}\right)=(-5)(-15)\\\\3n=75\qquad\text{divide both sides by 3}\\\\n=25
