Answer:

See below.

Step-by-step explanation:

Let x = the first number

Let y = the second number

First sentence: Equation 1: x+y=15

Second sentence: Equation 2: y=x+1

Part 2: Find the numbers.

x + y = 15

y = x + 1

x + x + 1 = 15

2x + 1 = 15

2x = 14

x = 7

y = x + 1 = 7 + 1 = 8

The numbers are 7 and 8.

Answer:

x = 7

y = 8

Step-by-step explanation:

x + y = 15

y = x + 1

Part 2:

x + (x + 1) = 15

x + x + 1 - 1 = 15 - 1

2x = 14

2x/2 = 14/2

x = 7

y = 7 + 1

y = 8

Therefore, x = 7 and y = 8

Answer:

m∠ONP = 43*

m∠LNO = 137*

m∠MNP = 137*

Step-by-step explanation:

Each line segment is a straight line meaning they are each worth 180°, so if you take 43° from 180° you're eft with 137° which is what ∠LNO and ∠MNP are equal to. ∠ONP is 43° since it is a vertical angle to ∠MNL which is also 43°.

Answer:

The median is 8

Step-by-step explanation:

4+4=8

It is 8 because the middle numbers there are 4 and 4

Welllllll.....

If you take the square root of 9, it's 3

if you take the square root if 16, it's 4

I would guess it to be about 3.2

Answer:

Step-by-step explanation:

Lily ,  we know that [tex]3^{2}[/tex] =9  and [tex]4^{2}[/tex] = 16  so we know that  [tex]x^{2}[/tex] = 10  , where 10 is an answer to x squared,  then X lies between 3 and 4   ,  see?

Answer:

The vertex is (-2,5). And the y intercept of the graph is (0,-7)

Step-by-step explanation:

The third side is [tex]\sqrt{42}[/tex]

So Pythagorean's theorem is the following

[tex]Short^2 + Long^2 = Hypotenuse^2[/tex]

From here we can input the following information that we know

[tex]Short^2 + 4\sqrt{3}^2 = 8^2\\Short^2 + 12 = 64\\Short^2 = 64 - 12\\Short^2 = 42\\Short = \sqrt{42}\\[/tex]

Answer:

Step-by-step explanation:

Area of a parallelogram is base x height

The base of the given parallelogram is 9 inches and the height is 7.5 inches

So, its area would be

9 x 7.5

Area equals [tex]67.5^{2}[/tex]

Answer:

Width = x mile = 4 4/9 mile

J.4 4/9

Step-by-step explanation:

Area of a rectangle = length × width

Area of the rectangular plot = 8/3 square miles

Length = 3/5 mile

Width = x mile

Area of a rectangle = length × width

8/3 = 3/5 * x

8/3 = 3/5x

x = 8/3 ÷ 3/5

Multiply 8/3 by the reciprocal of 3/5

x = 8/3 × 5/3

= (8*5) / (3*3)

x = 40/9

x = 4 4/9 mile

Width = x mile = 4 4/9 mile

Answer:

3.25 or 3 and 1/4

Step-by-step explanation:

The algebraic equation is 2x = 6.5.

Divide by 2 to get your answer.

6.5 divided by two is 3.25.

x = 3.25

Step-by-step explanation:

Answer:

price of an adult ticket = a = $7

price of a student ticket = s = $6

Step-by-step explanation:

price of an adult ticket = a

price of a student ticket = s

7a + 7s = 91 (1)

14a + 12s = 170 (2)

Multiply (1) by 2

7a + 7s = 91 (1) × 2

14a + 14s = 182 (3)

14a + 12s = 170 (2)

Subtract (2) from (3) to eliminate x

14s - 12s = 182 - 170

2s = 12

s = 12/2

s = 6

Substitute s = 6 into (1)

7a + 7s = 91 (1)

7a + 7(6) = 91

7a + 42 = 91

7a = 91 - 42

7a = 49

a = 49/7

a = 7

price of an adult ticket = a = $7

price of a student ticket = s = $6

Answer:

m = x / n

n = 15

Step-by-step explanation:

Number of chairs per row = m

Number of rows = n

Number of people = x

Number of chairs per row, m = number of people, x / Number of rows, n

m = x / n

If number of attendees, x = 60 ;

Number of chairs per row, m = 4

The number of rows, n = number of attendees / number of chairs per row, m

Hence, n = 60 / 4 = 15 rows

Answer:

[tex]\displaystyle [-2, -1][/tex]

Step-by-step explanation:

To use the Elimination method, you must get rid of one pair of variables, so that one side is set to zero. So, in this case, we must get rid of [tex]\displaystyle x,[/tex]therefore we will split the second equation in negative half :

[tex]\displaystyle \left \{ {{y = 2x + 3} \atop {-\frac{1}{2}[y = 4x + 7]}} \right. \\ \\ \\ \left \{ {{y = 2x + 3} \atop {-\frac{1}{2}y = -2x - 3\frac{1}{2}}} \right. \\ \\ \frac{1}{2}y = -\frac{1}{2}; -1 = y, -2 = x \\ \\ \\ \boxed{[-2, -1]}[/tex]

Answer: The sample portion would less closely model the population proportion

Answer:

Answer is that is will less closely model to the total population.

Step-by-step explanation:

This is because there are less numbers to be chosen and will be harder to find a proper medium and mean.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

7(p+2)=5(p+4)

By distributive law

The eqn becomes :

7p + 14 = 5p + 20

collecting like terms ;

7p - 5p = 20 - 14

=> 2p = 6 and

:- P = 3 ( dividing both sides by 2)

P= 3 is the only solution to the equation above and it satisfies the equation.
