Answer:
1, 3, 7, 21!
Step-by-step explanation:
The solution to the equation is x = 20.
<u>Step-by-step explanation</u>:
The equation is 2( x – 5) = 9 – 3 x + 6 + 8 + 3 x + 7
2x - 10 = 30
2x = 30+10
2x = 40
x = 40/2
x = 20
Answer:
1/12
Step-by-step explanation:
Given the following :
Actual height of pyramid = 24 ft
Dimension of scaled model :
Height = 2ft ; width = 1ft
The scale factor is a number used to reproduce a reduced dimension of a model by multiplying the actual dimeznsion or size of the model or object.
Since the height is of the scaled model is less than the actual height of the pyramid ; then it could be said that the scale factor is a fraction, because reduction has occurred.
(Height of scaled model / height of actual pyramid)
(2ft / 24ft) = 1/12
