Answer:

-7

Step-by-step explanation:

You use the quadratic formula of [tex]ax^{2} +bx+c = 0[/tex] to get:

a = 1

b = 7

c = -13

then you plug that into x= (-b ± √b²-4ac)/(2a) :

x= ( -7 ± √7²- 4(1)(-13) )/(2(1))

[tex]x=-\frac{7}{2} + \frac{\sqrt{101}}{2} \\\\x=-\frac{7}{2} - \frac{\sqrt{101}}{2}[/tex]

The sum of these two x values turns out to be:

[tex]x=-\frac{7}{2} + \frac{\sqrt{101}}{2}+( -\frac{7}{2} - \frac{\sqrt{101}}{2} )= -\frac{14}{2} = 7[/tex]

Draw out a number line. Make sure -28 is on the number line, along with other optional values (such as 0 perhaps). At -28, plot an open circle or hole. This indicates this value is not part of the solution set. This is because there is no "or equal to" as part of the inequality sign. Then shade to the left to indicate values smaller than -28.

So in summary, you'll have an open hole at -28 and shading to the left.

Answer:

what is the word called for angles that form a straight line and are supplementary

Answer:

1/2pi

Step-by-step explanation:

Since the formula for circumference is 2*pi*r and we know the R=1 so the of the whole circle is 2pi. This is a quarter of a circle so the answer is 1/2pi

Answer:

This is the specific answer: 31.7515

Answer: 31.5

Step-by-step explanation:

To solve this ratio problem, you need the common ratio. Divide the amount of pounds by the amount of kilograms.

Step 1: Divide 100 pounds by 45 kilograms

100 ÷ 45 = 2.2

This is the common ratio

Step 2: Divide 70 pounds by 2.2

70 ÷ 2.2 = 31.5

This is the amount of kilograms in a 70 pound object

Answer:

D. x>7

Step-by-step explanation:

Multiply - and -3

x+3>10

Subtract 3 on both sides

x>7

(Remember you can only switch the symbol if you divide or multiply by negative it does not apply on addition or subtraction)

Hope this helps!

Answer:

It is D.

Step-by-step explanation:

Remove parentheses: x + 3 > 10

Subtract 3 from both sides: x > 10 - 3

Simplify 10 - 3 to 7: x > 7

40 + 15 + 0.25x = 45 + 0.35y

55 + 0.25x = 45 + 0.35y The only way you can do this is to assume that x and y are equal

subtract 45 from both sides

55 - 45 + 0.25x = 0.35x

10 + 0.25x = 0.35x Subtract 0.25x from both sides.

10 = 0.35x - 0.25x

10 = 0.1x Divide by 0.1

10/0.1 = x

x = 100 So if each car goes 100 miles, it should turn out to be the same no matter which company gets the rental.

Let's see if that is true.

Cost for the first company = 40 + 15 + 0.25x = 55 + 25 = 80 dollars.

Cost for the second company = 45 + 0.35x = 45 + 35 = 80 dollars.

Conclusion

Both rentals charge the same total amount when each car is driven 100 miles.

The charge is 80 dollars.

Answers:

1)10.80/12 =0.90

0.90+0.75=1.65

2)252/7=36 units

3)cost price = $9.25*225

= $2081.25

Selling price = $15.75*225

= $3543.75

Profit = Selling price - cost price

Profit = $3543.75 - $2081.25

=$1462.50

5) FV = L*(1 + rt),

Where FV is the amount to repay;  L is the borrowed amount (the loan amount) and "r" is the annual interest as decimal; t is the time.

In your case  L = 2400 dollars;  r = 8% = 0.08 (as decimal) and t = 0.5 of a year (6 months).

Therefore,

   FV = 2400*(1 + 0.08*0.5) = 2496.

In 6 months, Della Rilley must repay $2496

4) 654miles/55mph=11 hours, 53 minutes, 27 seconds ANS: ap.12 hours

time = distance/speed

6) 60*3=180mins

180/45=4

Ans: 4 days

7) This is a decrease of 8

a decrease of 28.57% rounded to two decimals

The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.

Answer:

First Question: 63 coins are not nickels.

Second Question: 63+n=91

Step-by-step explanation:

For your first question: 29+21=50 and 50+13=63. 63 coins are not nickels.

For your second question: You can do 29+21+13+n=91, I just simplified and said 63+n=91. You can choose.

Hope that this helps! Good luck with what you're working on!

Answer:

63 coins are not nickels.

Equation to find n:

91 - 63

Or

91 - n
