The question in English is
<span>Find the lesser of three consecutive numbers, if the sum of half of the smaller number plus one third of the larger number exceeds five to the number in between

Let
x---------> the smaller number
x+1------> </span>the number in between
x+2-----> the larger number
<span>
we know that
(1/2)*x+(1/3)*(x+2)=(x+2)+5
so
(x/2)+(x/3)+(2/3)=x+7
(3x+2x-6x)/6=(21-2)/3
-3x=114
x=-38

therefore
</span>the smaller number-------> x------> -38
the number in between------> x+1-----> -38+1-----> -37
the larger number-------------> x+2-----> -38+2----> -36

the answer is
the lesser of three consecutive numbers is -38

The answer in Spanish

Hagamos
x---------> el menor numero
x+1------> el numero del medio
x+2-----> el numero mayor

Conocemos lo siguiente
(1/2)*x+(1/3)*(x+2)=(x+2)+5
por lo tanto
desarrollando la ecuacion
(x/2)+(x/3)+(2/3)=x+7
(3x+2x-6x)/6=(21-2)/3
-3x=114
x=-38

nos queda que
el menor numero es -------> x------> -38
el numero del medio es ------> x+1-----> -38+1-----> -37
el numero mayor es -------------> x+2-----> -38+2----> -36

La respuesta es
El menor  de los tres numero consecutivos es -38

Ava wants to figure out the average speed she is driving. She starts checking her car’s clock at mile marker 0. It takes her 4 m
VLD [36.1K]
<h2>Answer:</h2>

The average speed of car is:

                 0.75 miles per minutes.

The equation of line is:

                    n=\dfrac{3}{4}t

<h2>Step-by-step solution:</h2>

The table that describes the time and number of  miles marked is given by:

Time       Miles

  0              0

  4               3

  8               6

Clearly we could observe that with the increase in time by every 4   minutes the number of mile increases by 3.

i.e. the average speed is calculated as the ratio of change in miles to the change in time.

Hence,

Average\ Speed=\dfrac{3-0}{4-0}\\\\\\i.e.\\\\\\Average\ Speed=\dfrac{3}{4}=0.75

Hence, the average speed=0.75 miles per minutes.

Also we will find the equation of the lines that related the miles and time by using the two-point formula.

i.e. any line passing through (a,b) and (c,d) is calculated by using the formula:

y-b=\dfrac{d-b}{c-a}\times (x-a)

Here (a,b)=(0,0) and (c,d)=(4,3)

i.e. the equation is given by:

n-0=\dfrac{3-0}{4-0}\times (t-0)\\\\i.e.\\\\n=\dfrac{3}{4}t

Anna gets paid $8.75/hour working as a barista at Coffee Break. Her boss pays her $9.00/hour for creating the weekly advertiseme
vladimir1956 [14]

Answer:

i believe it would be $443.75

Step-by-step explanation:

just add 8.75 to 9.00 then multiply it by 25

8.75+9.00= 17.75 x 25= 443.75

if its a different type of equation then maybe this didn't help but i hope it does

Why is sin(20) = sin(160) = -sin(200) = -sin(340)?
AveGali [126]
Because they're all the same distance from the x axis on a coordinate plane. Also, remember that in quadrant I, all trig values are positive. In Q II, only sine and cosecant are positive. In Q III, only tangent and cotangent are positive. In Q IV, only cosine and secant are positive. Think of it as <u>A</u>ll <u>S</u>tudents <u>T</u>ake <u>C</u>alculus.

Tamika builds a wooden skateboard ramp. The ramp measures 63 centimeters, and the length of its horizontal base is 60 centimeter
Softa [21]
So imma be using the Pythagorean Theorem, which is a^2+h^2=c^2. The a and h variable represent the legs of the right triangle while c variable stands for the hypotenuse. And since we have one of the legs and the hypotenuse, we are solving for the other leg.

So first we are gonna plug in 60 and 63 in their appropriate spots: 60^2+h^2=63^2

Solve the exponents to get 3600+h^2=3969

Subtract 3600 on each side to get h^2=369

To cancel out the squared power, you have to square root each side of the equation, and your final answer should be h=19.2cm
