-2x + 100 = 5x + 20

100 - 20 = 7x

80 = 7x

80/7 = x

Write the equation of an ellipse with center (-2,-3), vertical major axis of length 14, and minor axis of
Tems11 [23]

Step-by-step explanation:

Since we have a vertical major axis, our ellipse is vertical.

The equation of a vertical ellipse is

\frac{(y - k) {}^{2} }{ {a}^{2} }  +  \frac{(x - h) {}^{2} }{ {b}^{2} }  = 1

where

(h,k) is the center

a is the semi major axis,

b is the semi minor axis

First, let plug in our center

\frac{(y + 3) {}^{2} }{ {a}^{2} }  + \frac{(x + 2) {}^{2} }{ {b}^{2} }  = 1

Semi means half, so

a is half of 14 which is 7

B is half of 8, which is 4.

\frac{(y + 3) {}^{2} }{49}  +  \frac{(x + 2) {}^{2} }{16}  = 1

A bag contains 25 kg of flour. A baker used 80% of it to bake bread. How much flour,in kg,remained ?​
SIZIF [17.4K]

Answer:

5 kg flour remains

Step-by-step explanation:

80% of the original 25 kg comes to 0.80(25 kg), or 20 kg.  We convert 80% to its decimal equivalent, 0.80, to get this result  

The amount of flour remaing is then (1.00 - 0.80)(25 kg), or 0.20(25 kg) = 5 kg.

5 kg flour remains.
