Answer:
-4
Step-by-step explanation:
Ok so you get two sets of proportional pairs: -3 and -1 , and -30 and -10.
The relationship between these is that the first term is 3 times the second. So you divide the first term by 3 to get the second.
So you divide -12 by 3 to get -4.
Hope this helps!
.04(2x)+.03(x)+.05(500+x)=2025
.08x+.03x+.05x+25=2025
.16x+25=2025
.16x=2000
x=12500

Answer:
<u>19</u> is the numerical value
Step-by-step explanation:
Also, when it's converted to number I.e.
E = 14 , B = 11
= 14 + 11 = 25
But in letters the numerical value is
E + B = 19
Answer:
16. 3
17. 12 / 7
18. 24 / 5 ( or ) 4.8
Step-by-step explanation:
16.
2 / ( x - 1 ) = 1
2 = x - 1
x = 2 + 1
x = 3
17.
( x / 3 ) + ( x / 4 ) = 1
LCM ( 3, 4 ) = 12
x / 3 = 4x / 12
x / 4 = 3x / 12
( x / 3 ) + ( x / 4 ) = 1
( 4x / 12 ) + ( 3x + 12 ) = 1
( 4x + 3x ) / 12 = 1
7x / 12 = 1
7x = 12
x = 12 / 7
18.
( x / 3 ) + ( x / 2 ) = 4
LCM ( 3, 2 ) = 6
x / 3 = 2x / 6
x / 2 = 3x / 6
( x / 3 ) + ( x / 2 ) = 4
( 2x / 6 ) + ( 3x / 6 ) = 4
( 2x + 3x ) / 6 = 4
5x / 6 = 4
5x = 24
x = 24 / 5
( or )
x = 4.8
