Answer:

D

Step-by-step explanation:

Solve all inequalities.

Given inequality:

-2x>-14\ [\text{Divide by -2, this will change the sign of the inequality}]\\ \\x

A.

-7x7

B.

3.5>-0.5x\ [\text{Divide by -0.5, this will change the sign of the inequality}]\\ \\-7-7

C.

3x\le 21\ [\text{Divide by 3}]\\ \\x\le 7

D.

35>5x\ [\text{Divide by 5}]\\ \\7>x\\ \\x

As you can see inequality in option D has the same solution set as given inequality.

A function has the function rule y = -7 x - 2. If the input is -4, what is the output? 26 -30 -26 14
GaryK [48]

Answer:

26

Step-by-step explanation:

Since the input is -4, x = -4. The equation then is y = -7(-4) -2

A negative times a negative is a positive, so -7 times -4 is 28.

Now the equation reads y = 28 - 2

Then obviously you just subtract the two and then you get 26.

Paha777 [63]

Answer:

She made an error when using the zero pair.

Step-by-step explanation:

In step 2, Carianne added 4 to the right side and subtracted 4 on the left side, which is completely changing the equation. By definition, your zero pair must have a difference of zero. She need to add 4 to both sides to continue; when manipulating algebra you need to do the same thing to both sides of an equation, otherwise you're just changing the equation.

el 18% de los arboles del jardin de la plaza mayor son almendros y el resto son naranjos. si en la plaza 45 almendros, ¿ cuantos
andre [41]

Queremos resolver un problema sobre porcentajes, donde conociendo el porcentaje que un dado número representa, queremos encontrar el número equivalente al 100%.

Veremos que el número total de arboles es 250.

------------------------------------

Sabemos que el 18% de los arboles son almendros y el resto son naranjos, es decir, el porcentaje de naranjos es 100% - 18% = 82%

Y sabemos que hay 45 almendros.

Entonces el <u>18% del número total de arboles es 45.</u>

Es decir, si hay N arboles en total, el 18% de N es igual a 45, esto se puede escribir como:

(18%/100%)*N = 45

0.18*N = 45

N = 45/0.18 = 250

Así podemos concluir que hay un total de 250 arboles en la plaza.
