Answer:
Step-by-step explanation:
<em>1).</em> x = 0 ⇒ <em>x = 0</em>
<em>2).</em> 5,4 ( x + 6,3 ) = 0 ⇒ x + 6,3 = 0 ⇒ <em>x = - 6,3</em>
<em>3).</em> ( x - 3 )( x + 4 ) = 0 ⇒ x - 3 = 0 или x + 4 = 0 ⇒ <em>x = 3</em> <u><em>или</em></u> <em>x = - 4</em>
<em>4).</em> 23,5 | x | = 0 ⇒ | x | = 0 ⇒ <em>x = 0</em>
Answer:
Chris have 24 local stamps
Step-by-step explanation:
We are given that The ratio of the number of local stamps to foreign stamps is 1 : 3.
Let the ratio be x
Number of local stamps = x
Number of foreign stamps = 3x
Total Number of stamps =x+3x=4x
We are given that Chris has 96 local and foreign stamps altogether in his collection
So, 4x=96
x=24
Hence Chris have 24 local stamps
