-2 (x+1) = -2x +5
-2x+-2 = -2x+5
+2 +2
-2x=-2x+7
+2x +2x
0=7
At this point, you can see that the solution is unsolvable. Obviously, zero does not equal seven. There are zero solutions to the equation

-2(x + 1) = -2x + 5

mutiply the bracket by -2

(-2)(x)= -2x

(-2)(1)= -2

-2x-2= -2x+5

move -2x to the left side

sign changes from -2x to 2x

-2x+2x-2= -2x+2x+5

0-2= 0-5

-2= -5

Answer:

no solution

The diameter of a circle is 14 inches. Find the circumstance and area use 22/7
s344n2d4d5 [400]

Answer:

Circumference= 44 in

Area= 154 in²

Step-by-step explanation:

\boxed{circumference \: of \: circle = 2\pi  r}

Radius

= diameter ÷2

= 14 ÷2

= 7 in

Circumference of circle

= 2( \frac{22}{7} )(7)

= 44 in

\boxed{area \: of \: circle = \pi {r}^{2} }

Area of circle

=  \frac{22}{7} ( {7}^{2} )

= 154 in²

A small cargo plane currently has 140 pounds of cargo aboard. In addition, n boxes weighing 45 pounds each will be brought aboar
Vika [28.1K]

Answer:

The inequality that represents this situation is: 140 + 45*n < p

Step-by-step explanation:

Since the plane already had 140 pounds on board and "n" boxes will be loaded on it, then the weigh of each box multiplied by the number of box should be the extra cargo on the plane. This extra cargo added to the previous load must be less than the limit of cargo the plane can take as shown below:

140 + 45*n < p
