You have $15.00 to buy watermelon for a picnic. A watermelon costs $3.75. Which inequality represents the number 3 of watermelons you can
buy? PLEASE HELP !!!

Answer:

x=2  y=−1 so (2,-1)

Step-by-step explanation:

2x+y=3

x=3y+5

​Consider the second equation. Subtract 3y from both sides.

x−3y=5

To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the results for that variable in the other equation.

2x+y=3,x−3y=5

Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.

2x+y=3

Subtract y from both sides of the equation.

2x=−y+3

Divide both sides by 2.

x=1/2(−y+3)

Multiply 1/2  times −y+3.

x=−1/2y+3/2

Substitute y+3/2  for x in the other equation, x−3y=5.

−1/2y+3/2−3y=5

Add −y/2 to −3y.

−7/2y+3/2=5

Subtract 3/2 from both sides of the equation.

−7/2y=7/2

Divide both sides of the equation by −7/2, which is the same as multiplying both sides by the reciprocal of the fraction.

y=−1

Substitute −1 for y in x=−1/2y+3/2. Because the resulting equation contains only one variable, you can solve for x directly.

x=−1/2(−1)+3/2

Multiply −1/2 times −1.

x=1+3/2

​Add 3/2 to 1/2  by finding a common denominator and adding numerators. Then reduce the fraction to the lowest terms if possible.

x=2

The system is now solved.

x=2,y=−1

Answer:

34

Step-by-step explanation:

A triangle will add up to a degree of 180, so if you add those 2 angles then subtract it from 180 you will get the answer. So, 115+31=146 then 180-146=34

So the answer is 34

Answer:

b = 34 degrees

Step-by-step explanation:

*triangles have an interior angle of 180 degrees

to find b, take the known angles (115 and 31) add them together and subtract the sum from 180:

⇒ 180 - (115 + 31)

solve:

⇒ 180 - 146 = 34

b = 34

Answer:

J

Step-by-step explanation:

Since the final tempurature means the final point of the line, you can see the point that ends is on (7, 0). The order for coordinate points is (x, y) and the point ends on 7 on the x-axis and 0 on the y-axis. Hope this helped!

Answer:

A=166 in²

Step-by-step explanation:

A=2(wl+hl+hw)

A= 2(5x7+4x7+5x4)

A=2(35+28+20)

A=2(83)

A=166 in²

Answer: Not possible

Step-by-step explanation:

Given

The length of Jaylen's bed is [tex]6\ ft\approx 72\ in.[/tex]

The length of his desk is [tex]3\ ft\approx 36\ in.[/tex]

The total length along the wall is [tex]125\ in.[/tex]

Jaylen wants [tex]2\ ft \approx 24\ in.[/tex] gap between bed and desk

the combined length of bed and desk is

[tex]\Rightarrow 72+36=108\ in.[/tex]

The remaining length after placing the bed and desk is

[tex]\Rightarrow 125-108=17\ in.[/tex]

As the remaining length is less than the required length

Therefore, it is not possible to leave a gap of two-foot between the bed and desk

Answer:

80°

Step-by-step explanation:

42° + 58° + x = 180° [Angle sum property of triangle]

=> 100 + x = 180

=> x = 180 - 100

=> x = 80 (Ans)

Step-by-step explanation:

58° + 42° + x = 180° -- (Δ sum property)

100° + x = 180°

x = 180° - 100°

x = 80°

Answer:

Not a solution

Step-by-step explanation:

y=x-5

Plug in the point (6,11)

11=6-5

11=1

11≠1

Because the left side of the equation and the right side aren't equal, the ordered pair (6,11) is not a solution to the equation y=x-5.

I hope this helps!

Answer:

It isn't a solution of the equation.

Step-by-step explanation:

(x, y) = (6, 11)

You replace the values ok the equation:

11=6-5

11=1 Which is FALSE so it isn't a solution of the equation.

Answer:

Step-by-step explanation:

use  SOH CAH TOA

Sin = Opp / Hyp

Cos = Adj / Hyp

Tan = Opp / Adj

then we know the adjacent side and the angle, and want to find the Hyp, so use  CAH

Cos(60) = ( 8[tex]\sqrt{3}[/tex]  / 3 ) / Hyp       ( cos(60) = 1/2 )

Hyp = (8[tex]\sqrt{3}[/tex] / 3) / (1/2)

Hyp = 2 ((8[tex]\sqrt{3}[/tex] / 3)

Hyp = 16[tex]\sqrt{3}[/tex] / 3

x =  16[tex]\sqrt{3}[/tex] / 3

Now use SOH

Sin (60) = Opp / 16[tex]\sqrt{3}[/tex] / 3      ( sin(60) = [tex]\sqrt{3}[/tex]/2 )

(16[tex]\sqrt{3}[/tex] / 3)([tex]\sqrt{3}[/tex]/2) = Opp

16 * 3 / 6  = Opp

8 = Opp

y = 8

Answer: -0.5

Step-by-step explanation:

5 + (-5.5) = -0.5 dollars

The expected return of placing this bet is -0.5 dollars.

Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favorable outcomes to all outcomes.

To calculate the expected return of this bet, we need to consider the possible outcomes and their probabilities. There are two possible outcomes:

The Denver Dragons win with a probability of 0.5. In this case, Ivy will win 10 dollars.

The Seattle Sea Turtles win with a probability of 0.5. In this case, Ivy will lose 11 dollars.

To calculate the expected return, we multiply each outcome by its probability and sum the results.

Expected return = (0.5 x 10) + (0.5 x -11)

Expected return = 5 - 5.5

Expected return = -0.5

Therefore, the expected return of placing this bet is -0.5 dollars, which means that over the long run, Ivy can expect to lose an average of 50 cents every time she places this bet.

Answer:

117 ft²

Step-by-step explanation:

Surface area of triangular pyramid = base area + ½(Perimeter of base * slant height)

Base area = ½*b*h = ½*9*6 = 27 ft²

Slant height = √(6² + 4.5²) = 7.5 ft (pythagorean theorem)

Perimeter = 7.5 + 7.5 + 9 = 24 ft

Plug in the values into the formula for surface area

Surface area = 27 + ½(24 * 7.5) = 117 ft²

Answer:

35 feet

Step-by-step explanation:

We'll begin by calculating the resultant for you and your friend.

For you:

R² = 12² + 9²

R² = 144 + 81

R² = 225

Take the square root of both side

R = √225

R = 15 feet

For your friend:

R² = 16² + 12²

R² = 256 + 144

R² = 400

Take the square root of both side

R = √400

R = 20 feet

Finally, we shall determine the distance between you and your friend.

The distance between you and your friend is obtained by adding your resultant and that of your friend together i.e

You resultant = 15 feet

Your friend's resultant = 20 feet

Distance between you and your friend = 15 + 20 = 35 feet.

Therefore, you threw the baseball 35 feet away from your friend.
