Answer: No, the ordered pair (2,5) is not a viable solution

===========================================================

Explanation:

(2,5) means that b = 2 and h = 5

I'm assuming each ordered pair is of the form (b,h) where b comes first, since b is before h in the alphabet.

So if b = 2 and h = 5, then we can replace each letter with those numbers to get the following:

5b + 3h = 45

5*2 + 3h = 45 ..... b replaced with 2

5*2 + 3*5 = 45 ..... h replaced with 5

10 + 15 = 45

25 = 45

We don't get the same number on both sides, so (b,h) = (2,5) is not a solution.

--------------

Put another way:

If b = 2 and h = 5, this means you bought 2 burgers and 5 hot dogs

1 burger = $5

2 burgers = 2*5 = $10

1 hot dog = $3

5 hot dogs = 5*3 = $15

total amount spent = $10 + $15 = $25

total amount spent = $25

This does not match up with the $45 total spent that we're given. So this is another way to see we don't have a solution.

Answer:

x = -5

y = 20

Step-by-step explanation:

3x + y = 5

3x - 3x + y = 5 - 3x

y = 5 - 3x

--------------------------------------------------------

4x + 2y = 20

4x + 2(5 - 3x) = 20

4x + 2(5) + 2(-3x) = 20

4x + 10 - 6x = 20

10 - 2x = 20

10 - 10 - 2x = 20 - 10

-2x = 10

-2x ÷ -2 = 10 ÷ -2

x = -5

--------------------------------------------------------

y = 5 - 3x

y = 5 - 3(-5)

y = 5 + 15

y = 20

Answer:

p=4.9

Step-by-step explanation:

Answer:

4.9

Step-by-step explanation:

[tex]2.5 + 3(5 - 2.1p) = - 13.37[/tex]

1) Open the brackets by multiplying 3 with each term present inside the bracket.

[tex] = > 2.5 + 15 - 6.3p = - 13.37[/tex]

2) Add the constant teems present in left-hand side.

[tex] = > 17.5 - 6.3p = - 13.37[/tex]

3) Take 17.5 to right-hand side by changing its sign from positive to negative.

[tex] = > - 6.3p = - 13.37 - 17.5[/tex]

[tex] = > - 6.3p = - 30.87[/tex]

4) Take -6.3 to right-hand side by dividing -30.87 by --6.3.

[tex] = > p = \frac{ - 30.87}{ - 6.3} = 4.9[/tex]

Answer:  The dimensions of the rectangle are 7 cm × 4 cm

Step-by-step explanation:

let,

Breadth of the rectangle (l) = x

Length of the rectangle (b) = x + 3

Area of the rectangle = 28 cm²

Area of the rectangle = l × b

⇒ (x) × (x + 3) = 28

⇒ x² + 3 x = 28

⇒ x² - 3 x - 28 = 0  

⇒ x² - 7 x + 4 x - 28 = 0

⇒ (x - 7) + 4(x - 7) = 0

⇒ (x - 7)(x + 4) = 0

⇒ x = 4

Breadth = 4 cm

Length -

⇒ 4 + 3

⇒ 7 cm

The steps to find an outlier:

1. Put the data in numerical order.

2. Find the median.

3. Find the medians for the top and bottom parts of the data. This divides the data into 4 equal parts.

The median with the smallest value is called Q1. The median for all the values - usually just called the median is also called Q2. The median with the largest value is Q3.

4. Subtract...Q3 - Q1. This value is the InterQuartileRange or IQR. Remember that the range means taking the largest minus the smallest. This is a special range having to do with the quartiles.

5. Multiply...1.5 * IQR

6. Take your answer from #5 and do 2 things with it. A). Subtract it from Q1 and B) Additional to Q3.

7. Look at all your data points. If any are SMALLER than Q1 - 1.5 *IQR, they are outliers. If any are LARGER than Q3 + 1.5 *IQR, they are also outliers.

For your data....the median, Q2 is

(43+38)/2 = 40.5.

Q1 = (30+26)/2 = 28.

Q3 = (54+52)/2 = 53

The IQR is 53 - 28 = 25

1.5 * IQR = 37.5

Q1 - 37.5 = 28 - 37.5 = -9.5. There is no data value less than -9.5.

Q3 + 37.5 = 53 + 37.5 = 90.5. there is no data value greater than 90.5.

My conclusion is that there are no outliers in this data.

I hope this helps!

Answer:

sin x = 0.85

Step-by-step explanation:

since,

sin x = opposite/hypotenuse

= 11 / 13

sin x = 0.85

Answer:

4, and -9

Step-by-step explanation:

Well, to solve this problem, lets first list all the factors of -36.

-36 = 1*(-36)

-36 = 2 * (-18)

-36 = 3 * (-12)

-36 = 4 * (-9)

-36 = 6 * (-6)

-36 = 12 * (-3)

-36 = 18 * (-2)

-36 = (-36) * 1.

So, we can see that 4 + (-9) = -5.

Answer:

A: Hannah ran 0.7 miles on Tuesday

B: They ran 1.45 miles in total

Step-by-step explanation:

If you put all the fractions into decimal form it would be;

1/2 = 0.5

1/5 = 0.2

3.4 = 0.75

So, you add all of the decimals together;

0.5 + 0.2 = 0.7

0.7 + 0.75 = 1.45

☁️My Answer☁️:

y = 90°

✧My Step-by-step explanation✧:

The angle x forms a straight line with the both the 50° angle and the 40° angle:

x + 50° + 40° = 180°

x = 90°

Which means…

y = x = 90°

Answer:

[tex]48\ \text{feet}[/tex]

Step-by-step explanation:

[tex]1\ \text{inch}[/tex] of the model is [tex]4\ \text{feet}[/tex] of the actual pole.

Here, the pole which is present in the model measures [tex]12\ \text{inches}[/tex], so

[tex]12\ \text{inches}[/tex] of the model will be [tex](12\times 4)\ \text{feet}=48\ \text{feet}[/tex]

Hence, the actual pole will be [tex]\boldsymbol{48\ \text{feet}}[/tex] tall.

Answer:

do you mean a big mac and a smoothie?

Step-by-step explanation:

Answer:

no solution

Step-by-step explanation:

x²-4 is (x+2)(x-2), which is your least common multiplier

So first, eliminate the denominators by multiplying all terms by (x+2)(x-2)

(x+2)(x-2)/(x-2) + (6x)(x+2)(x-2)/(x+2)(x-2) = 3(x+2)(x-2)/(x+2)

Then simplify

(x+2) + (6x) = 3(x-2)

combine the variables, and expand the right side of the equation

7x + 2 = 3x - 6

Subtract 2 from both sides

7x = 3x - 8

Substract 3x from both sides

4x = -8

Divide both sides by 4

x = -2

Although x = -2, the final answer is undefined.

Because if you plug x = -2 back into the equation, you would get...

for example, 3/(x+2) will become 3/(-2+2), which is 1/0

it is not possible to divide by 0

anything divided by 0 is undefined, therefore this equation has no solution.

Answer:

3,4 and 5 are correct........☺

Answer:

3,4,5

Step-by-step explanation:

To answer, we must go through all the expressions shown, solve them, and make sure that they are exactly like 3xy + 6yz.

1. We must distribute 3 to whatever is in the parentheses, but if you look, you can see that we have to multiply 3 by 6yz, which would come out to 18yz, and that is not in the original expression, so this one is FALSE

2. For this expression, we can rule it out because the first part of the expression would be 3xyz, and that is not a part of the original expression, this is one is FALSE

3. This expression, if you distribute the 3y, you get 3yx + 6zy, which is the same as the original expression, even if the variables are a bit jumbled, they all have the same value, so this one is TRUE

4. If you distribute y for this expression, you get y3x + y6z, which is the same as the original expression, because as I said before, the variables can be jumbled, but as long as all the values are there, we can safely say that this expression is TRUE

5. As you can see, this expression is the same as 4, so this one is also TRUE

Hope this helps :)
