Answer:

where is the question?

Step-by-step explanation:

you just said to estimate the value of what x can be.

Answer:

39

Step-by-step explanation:

In words, Elise's statement can be expressed as follows:

(x-13)(-7) = -182

where x is the number. Working it out you get:

x-13 = 26

x=39

Answer:

39

Step-by-step explanation:

let's use 26 as x

26-13=13*-7=-182

-182 /-7= 26

26+13=39

Step-by-step explanation:

Answer:

Step-by-step explanation:

The formula for solving this is

P=mgh

M=80kg

h=15m

g=9.8 (acceleration due to gravity constant)

P=?

Then we should substitute our values

P=80×9.8×15

Potential energy=11760

Given:

Number of students = 35

Two out of every five boys in the club are boys.

To find:

The number of students in the club that are boys.

Solution:

Two out of every five boys in the club are boys. It means, the ratio of boys to the total number of student is 2:5.

Let the number of boys be 2x and number of students be 5x.

According to the question,

[tex]5x=35[/tex]

[tex]x=7[/tex]

Now, the number of boys is

[tex]2x=2(7)[/tex]

[tex]2x=14[/tex]

Therefore, 14 students in the club are boys.

Answer:

2 more quarts of oil is needed to fill

the engine to capacity

Step-by-step explanation:

Here, we want to calculate how many more quarts of oil is required to fill the engine to capacity

We have to convert the capacity to quarts

Mathematically, 1 gallon = 4 quarts

So 1 1/4 gallon will be 5/4 * 4 = 5 quarts

So the number of quarts needed to fill the engine to capacity will be 5 quarts - 3 quarts = 2 quarts

Answer:

f⁻¹(x) = x+2 / 3

Step-by-step explanation:

Given function is:

f(x) = 3x-2

We have to find the inverse of the given function.

Put y = f(x)  in given function, we have

y =3x-2

Adding 2 to both sides of the above equation we have

y+2 = 3x-2+2

y+2 = 3x

Dividing by 3 to both sides of the above equation, we have

y+2 / 3 = 3x / 3

y+2 / 3 = x

Put x = f⁻¹(y) in the above equation we have

y+2 / 3 = f⁻¹(y)

Swapping equation we have

f⁻¹(y) = y+2 / 3

Replace y with x we have

f⁻¹(x) = x+2 / 3   which is the answer.

Answer:

Vamos a definir:

100% probabilidad de lluvia = Es seguro que ese día va a llover.

0% probabilidad de lluvia = Es seguro que ese día no va a llover.

Ahora, los valores intermedios admiten una dualidad, es decir, es posible que llueva o que no.

Particularmente en el caso del 70% significa que:

Si tenemos un dado de 10 caras, con los números {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Y lo tiráramos, los resultados {1, 2, 3, 4, 5, 6, 7} indicarían que llueve.

Los resultados {8, 9, 10} indicarían que no llueve.

Entonces es mas probable que llueva, pero la probabilidad de que no llueva no es despreciable.

Answer:

Use 12 more pounds of pasta.

Step-by-step explanation:

A restaurant uses 3 pounds of pasta for a party of 14 people. If they are cooking pasta for a party of 56 people, what should they do?

Hence, we have:

14 people = 3 pounds of pasta

56 people = x

Cross Multiply

14 × x = 56 × 3

14x = 56 × 3

x = 56 × 3/14

x = 12 pounds of pasta

Hence, if they are cooking for 56 people they should use 12 pounds of pasta

The distance a baseball travels when a player hits the ball varies directly with the speed with which the player swings the bat. The graph below shows the distances a baseball travels (in feet) and the speed of the swing (in miles per hour). A graph titled Baseball Speed has speed of swing (in miles per hour) on the x-axis, and distance (in feet) on the y-axis. A line goes through points (0, 0), (40, 200), (60, 300). Based on the graph, which relationship exists between the speed of the swing and the distance the ball travels?

Answer: the realtionship between exists is (50, 145)

Answer:

The distance is 5 times the swing speed. or c

Step-by-step explanation:

its number 2

Answer:

1. 1, 2. -15, 3. -18, 4. -1, 5. -11. 6. 22

Step-by-step explanation:

REMEMBER: If a positive multiplies a negative, it will result in a negative. If a negative multiplies a negative, it will resolve as a positive

1. 7 - 2 x 3 = 1

First, multiply 2 and 3 to get 6

7 - 6

Subtract the numbers to get 1

2. -8 + 14 / (-2) = -15

First, do 14 divided by -2 to get -7

-8 + -7

Add the two numbers to get -15

3. -6 + (-3) x 4 = -18

First, multiply -3 and 4 to get -12

-6 + -12

Add the two numbers together to get -18

4. 48 / (-12) +3 = -1

Divide 48 and -12 to get -4

-4 + 3

Add the two numbers to get -1

5. 16 / (-2) -3 = -11

Divide 16 by -2 to get -8

-8 - 3 = -8 + (-3)

Add the two numbers together to get -11

6. -11 x 4 / (-2) = 22

Work the problem from left to right, start with -11 x 4 to get -44

-44 / -2

Divide the equation to get 22
