Answer:
w3
Step-by-step explanation:
move the constant to the right hand side and change it's sign
calculate the difference
divide both sides of the equation by 4
9514 1404 393
Answer:
w = 3
Step-by-step explanation:
Isolate the w term by subtracting the constant on that side.
75 -75 -4w = 63 -75
-4w = -12
Get w by itself by dividing by its coefficient.
-4w/-4 = -12/-4
w = 3
Determina la EPG que adquiere una trapesista de 52 kg de masa cuando sube a un trapecio de 8 metros de altura. Considera g=9.81
Responder:
4080,96 Julios
Explicación paso a paso:
La energía potencial gravitacional adquirida se puede obtener mediante la relación:
EPG = masa * aceleración por gravedad * altura
Masa = 52 kgb; aceleración debida a la gravedad = 9,81; h = 8 metros
EPG = 52 * 9,81 * 8
EPG = 4080,96 julios

find the solution to the system of equations
Answer:
(-3, -4)
Step-by-step explanation:
y= -4
so you plus y in for the y=2x+2 equation where you get x=-3
[tex]\huge\text{Hey there!}[/tex]
[tex]\large\text{If y = -4 then SUBSTITUTE it into the EQUATION}[/tex]
[tex]\large\text{-4 = 2x + 2}[/tex]
[tex]\large\text{TURN the EQUATION}[/tex]
[tex]\large\text{2x + 2 = -4}[/tex]
[tex]\large\text{SUBTRACT by 2 to BOTH SIDES}[/tex]
[tex]\large\text{2x + 2 - 2 = -4 - 2}[/tex]
[tex]\large\text{CANCEL out: 2 - 2 because that gives you 0}[/tex]
[tex]\large\text{Keep: -4 - 2 because it helps us solve for x}[/tex]
[tex]\large\text{2x = -6}[/tex]
[tex]\large\text{DIVIDE by 2 to BOTH SIDES }[/tex]
[tex]\mathsf{\dfrac{2x}{2}=\dfrac{-6}{2}}[/tex]
[tex]\large\text{CANCEL out: }\mathsf{\dfrac{2}{2}}[/tex] [tex]\large\text{because that gives you 1}[/tex]
[tex]\large\text{KEEP: }\mathsf{\dfrac{-6}{2}}[/tex] [tex]\large\text{because it gives us the value of x }[/tex]

Write the equation of a line that is
1
parallel to the line y =1/2
X-3 and passes
through the point (4, 6)?
Answer:
y = 1/2x + 4
Step-by-step explanation:
If it's parallel, then the slope will remain the same.
To find the y-intercept, you have to plug the coordinates into the equation.
y = 1/2x + b
6 = 1/2 (4) + b
6 = 2 + b
4 = b

Which would be the first step for solving the equation x + 2 = 18?
A. add - 2 to both sides of the equation
B. add 18 to both sides of the equation
c.
divide both sides of the equation by
7
16
D
multiply both sides of the equation by
7
Answer:
A. Add -2 to both sides
Step-by-step explanation:
The reason you need to add -2 to both sides is because if you add -2 to -2 it cancels out and you are left with x=18. But you need to add -2 to 18 too because them the equation won't be equal anymore.

143 inches = ________ a) 14 feet 3 inches b) 13 feet 9 inches c) 12 feet 2 inches d) 11 feet 11 inches
Answer:
D. 11 feet 11 inches
1 foot= 12 inches
143/ 12 = 11 11/12
Answer:
D) 11 feet and 11 inches
Step-by-step explanation:
First we know that there is 12 inches in a foot. So let's start with a.
14 inches x 12 inches (one foot) is 168 inches (so it's not this one:)
13 inches x 12 inches is 156 inches (It's not this one either)
12 inches x 12 inches is 144 inches (not this one)
11 inches x 12 inches is 132 inches (so it could be this one, let's add the remaining inches).
132 + 11 inches = 143 inches.
(Notice I didn't add the remaining inches on A, B, or C because the number of inches was already too much. I did on D because the number of inches was below the given number of 143.
Hope this helps!!
Have a wonderful day!!

A population of llamas stranded on a desert island is decreasing due to a food shortage by 6% per year. If the population of llamas started out at 350, how many are left on the island 10 years later?
Answer:
189
Step-by-step explanation:
Given data
Initial population=350
Rate = 6%
TIme= 10 years
Let us apply the compounding expression
A=P(1-r)^t----------The negative sign is due to decreasing value
substitute
A= 350(1-0.06)^10
A=350(0.94)^10
A=350*0.5386
A=188.51
Hence the approximate population will be 189

6. Three consecutive integers add up to 51. What are these integers?
Answer: 16,17,18
Step-by-step explanation:
(x)+(x+1)+(x+2) = 51
x+x+x+1+2=51
3x+3=51
3x=51-3
3x=48
x=16
x+1 = 17
x+2= 18
Let, the three consecutive integers be x, x+1 and x+2.

x = 16x + 1 = 17x + 2 = 18_____________________________2(length + width). What is the perimeter, in units, of a rectangle of length fraction 1 over 3 unit and width fraction 1 over 2 unit?
Answer:
1 and 2/3
Step-by-step explanation:
If
length = 1/3 and width= 1/2
then the equation will look like this,
2(1/3+1/2)
1/3+1/2= 5/6
2(5/6)= 1 and 2/3
A hot air balloon went from an elevation of 5,717 feet to an elevation of 3,388
feet in 34 minutes. What was its rate of descent?
The rate of the descent was
feet per minute.
Answer:
68.5 feet per minute
Step-by-step explanation:
rate of descent = feet / minute
First you need to find how many feet it has descended:
beginning altitude- ending altitude = total feet descended
5717 feet - 3388 feet = 2329 feet
To figure out the rate of decent we will divide
2329 feet / 34 minutes = 68.5 feet per minute
The hot air ballon descended 68.5 feet per minute for 34 minutes.
SE TIENE 45 NIÑOS Y 35 NIÑAS. DE LOS CUALES 60 VIVEN EN EL DISTRITO DE BREÑA. SI EL 30% QUE NO VIVEN EN BREÑA SON MUJERES. ¿QUÉ CANTIDAD SON VARONES?
Answer:
14 son varones
Step-by-step explanation:
Primero tenemos que sumar la cantidad de niños y niñas para saber cuantos hay en total
45 + 35 = 80
60 de ellos viven en el Distrito de Breña entonces los descontamos del total
80 - 60 = 20
Esto nos dice que 20 NO viven en Breña. Si 30% son mujeres quiere decir que el resto 70% son varones. Asi que multiplicamos los 20 por 70% en formato decimal que seria 0.70
20 * 0.70 = 14
Finalmente, podemos ver que 14 son varones viviendo fuera de Breña
