Answer:
S= 5, L= 12
Step-by-step explanation:
To find the value of L and S, we need to first label the 2 equations.
L +S= 17 -----(1)
3L +2S= 46 -----(2)
From (1):
L= 17 -S -----(3) <em>(</em><em>-S</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
Subst. (3) into (2):
3(17-S) +2S= 46
3(17) -3S +2S= 46 <em> </em><em>(</em><em>expand</em><em>)</em>
51 -S= 46
-S= 46 -51 <em>(</em><em>-51</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
-S= -5
S= 5 <em>(</em><em>divide</em><em> </em><em>by</em><em> </em><em>-1</em><em> </em><em>throughout</em><em>)</em>
Subst. S=5 into (3):
L= 17 -5
L= 12
Answer:
Step-by-step explanation:
It is given that a radio show last for h hours for every 60 minutes of air time during the show there are 8 minutes of commercials.
The expression
represents the air time in minutes available for talk and music .
Since bothe the terms in the given expression are like terms as they have same variable h.
So by combining like terms, we get the fllowing expression:
[Since 60-8=52]
Answer:
let the unknown number be = n, and the difference between the number be = X
7,X,n
X = 32/4
ans =8. 8 is the difference between 7 and n
where by n = 16
