Answer: m=11

Step-by-step explanation:

First since there are no m's on the other side you cancel out the 5 by adding 5 to -5 and then add 5 to 17 which will give you 22

2m-5=17

+5 +5

2m=22

Now you divide 2m by to get the variable m by itself then divide the other side by 2

2m=22

÷2. ÷2

Which leaves you with

M=11

Answer: m = 11

Step-by-step explanation:

In order to solve this equation, you have to bring the 5 to the 17. To cancel out the -5 add a five. Then do that to 17. Now you have 2m = 22. To isolate m, divide. 2m divided by 2 is m, and 22 divided by 2 is 11. M = 11.

Un prisma cuadrangular regular tiene 4 m de arista de la base y 6m de altura Calcula el area y el volumen

mario62 [17]

Answer:

El área y volumen del prisma cuadrangular mencionado son respectivamente:

Área = $16m^{2}$
Volumen = $96m^{3}$

Step-by-step explanation:

Para solucionar este ejercicio debes recordar que un prisma cuadrangular tiene como base y como superficie cuadrados, por lo tanto, para calcular el área de dicho cuadrado puedes utilizar la siguiente fórmula:

Área de un cuadrado = $arista^{2}$

Ya que el ejercicio nos da el valor de la arista (4 metros), podemos reemplazarla en la ecuación y calcular:

Área de un cuadrado = $(4m)^{2}$
Área de un cuadrado = $16m^{2}$

Por último, para calcular el volumen debes multiplicar el área superficial, el área del cuadrado calculado, por la altura del prisma, cuyo valor dentro del enunciado es de 6 metros, de esta forma:

Volumen de un prisma cuadrangular = área superficial * altura
Volumen de un prisma cuadrangular = $16m^{2}$ * $6 m$
Volumen de un prisma cuadrangular = $96m^{3}$

Como puedes ver tras los cálculos, el área superficial del prisma es de $16m^{2}$ y su volumen es $96m^{3}$ .

Assume that x is a char variable has been declared and already given a value. Write an expression whose value is true if and onl

Lorico [155]

Answer:

bool b = isupper(x);

Step-by-step explanation:

I have written the expression for a char variable x.The isupper(x) will return true if the character x is upper case and false if the character x is lower case.

I have stored the returned value to a bool variable b .So the value of variable b will be true only when the x is in uppercase and false when b is lower case.

Solve 2/3 - 6y = - 1 5/6

alukav5142 [94]

Answer:

y = 19/36

Step-by-step explanation:

Assuming that what you want is the value of y, you can pass all the right side stuff to the left, and the y to the right:

2/3 + 15/6 = 6y

Then you can sum the fractions on the left by using the same denominators:

4/6 + 15/6 = 6y ==> 19/6 = 6 * y

then you can pass the 6 that is multiplying on the right to the left - now dividing:

y = 19/36
