9

Answer:

[tex]x = 26 \frac{1}{3} \\ [/tex]

[tex]y = 13 \frac{2}{3} \\ [/tex]

Step-by-step explanation:

x = 2y - 1

x - 2y = -1 ________(1)

x + y = 40________(2)

(2) - (1)

[tex]x + y - (x - 2y) = 40 - ( - 1) \\ x + y - x + 2y = 40 + 1 \\ 3y = 41 \\ y = \frac{41}{3} \\ y = 13 \frac{2}{3} \\ [/tex]

y = 13 2/3

[tex]x + y = 40 \\ x + 13 \frac{2}{3} = 40 \\ x = 40 - 13 \frac{2}{3} \\ x = 40 - \frac{41}{3} \\ x = \frac{3(40) - 41}{3} \\ x = \frac{120 - 41}{3} \\ x = \frac{79}{3} \\ x = 26 \frac{1}{3} \\ [/tex]

Answer: 2 3/8

I got an A

Answer:

2 + 3/8

Step-by-step explanation:

Therefore we get 19 / 8 = 2 + 3/8 , which is written as 2 3/8 , called a mixed number. To convert 19/8 you do division; 8 into 19 goes 2 times with 3 left over; so 2 3/8.

Answer:

5:6

Step-by-step explanation:

when adding the two probabilities together, they should equal 6:6. So, 5:6 is the odds of winning.

The probability is the ratio of the favorable event to the total number of events. Then the probability that Bucksnot will win the race is 5/6.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

The odds against the horse Bucksnot winning the race are 1:6.

Then the probability that Bucksnot will win the race will be

[tex]\rm P = 1 - \dfrac{1}{6}\\\\P = \dfrac{5}{6}[/tex]

see photos for step to step solution

Step-by-step explanation:

9. a)

2•(-2) = 2 - 6

-4 = -4

-2 -2 = -2•2

-4 = -4

Yes, the ordered pair is the solution

9. b)

-1 = 3•(-2) +5

-1 = -6 +5

-1 = -1

3•(-2) +(-1) = -2

-6 -1 = -2

-7 ≠ -2

No, the ordered pair is not the solution

10. (-1, -1) and (3, -1)

11.

y = 6 +x

Now substitute it in the first equation:

3•(6 +x) = 5x

18 + 3x = 5x

18 = 2x

x = 18/2

x = 9

Now, substitute x = 9 in the second equation:

y -9 = 6

y = 6 +9

y = 15

Answer:c

Step-by-step explanation:i did it

The equation is y = 0.60x. Then the total cost of 9 lbs of bananas will be 5.4 lbs.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

The cost of bananas, y, is directly proportional to x, the pounds of bananas purchased. Then the relationship is given as,

y ∝ x

y = kx

Then the relationship between 'x' and 'y' will be linear.  If 2.5 lbs of bananas cost $1.50. Then we have

1.50 = k (2.5)

k = 0.60  

Then the equation is given as,

y = 0.60 x

Then the total cost of 9 lbs of bananas will be given as,

y = 0.60 (9)

y = 5.4 lbs

The equation is y = 0.60x. Then the total cost of 9 lbs of bananas will be 5.4 lbs.

Step-by-step explanation:

Adam's balance at the end of June is $627.27

The adjusting balance method is used to determine the interest that would be paid by a credit card owner. The interest that would be paid is determined at the end of a period after all transactions have been adjusted for.

For example, if I have $100 in my credit card. If I buy a shoe worth $50 and deposit $20. My balance at the end of the month would be ($100 + $50 - $20) = $130.

Adam's balance can be determined by adding the amount he spent on purchases to the beginning balance and subtracting the payments he made.

$626.45 + $37.41 + $44.50 - $65.5 +$24.89 - $104.77 +$23.60 + $15 + $51.85 = $605.23

The balance at the end of the month would be the sum of the interest and the amount in his balance

Interest earned = balance x interest rate

Interest rate = 14.63% / 4 = 3.66%

Interest earned = $605.23 x 0.0366 = $22.14

Balance = $22.14 + $605.23 = $627.37

$158,035.41 rounded to the nearest 10 dollars is $158,040

Step-by-step explanation:

Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place. If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is.

the value of roses is 4 dollars a pieces and that of daisies is 3 bucks a piece

Step-by-step explanation:

for part a just denote r for roses and rerecord the question in terms of a function of roses and daisies the right hand side should be the prices or cost

solve the two equations simultaneously or by substitution.

let's do simultaneous

multiply the secondequation by 5

[tex]5r + 4d = 32[/tex]

[tex]5r + 30d = 110[/tex]

subtracting the two,

[tex]26d = 78[/tex]

therefore

[tex]d = 3 dollars[/tex]

find the value of roses,

[tex]5r + 4(3) = 32 \\ 5r = 32 - 12 \\ r = 4[/tex]
