Answer:
38
Step-by-step explanation:
2(
+ab) + 3 - ab
=
+ 2ab + 3 - ab
=
+ ab + 3
= 2x
+ 5x(-3) + 3
= 50 - 15 + 3
= 38
Based on the above scenario, an equation that shows how much Gwen paid. The equation for Gwen is y = 100 + 10x
- The equation for Tristan is y = 12.5x
- The equation for Keith is y = 10x.
<h3>What is the
equation about?</h3>
Since Gwen burns about 10 cal/min. THen she had used up 100 calories if Tristan and Keith began ar (Y g=100 if x=0)
Then Y(g)= 10x + 100
Since Tristan is known to burns 125 cal in 10 minutes always, then one can write her own as 12.5 cal every minute.
Therefore Y (t) = 12.5x
Since Keith burns 300 calories in 30 min always, or 10 calories in every minute.
Then Y (k) = 10x
The general function of y:
y=10x +100 + 12.5x + 10x
y = 32.5x + 100
Therefore, Based on the above scenario, an equation that shows how much Gwen paid. The equation for Gwen is y = 100 + 10x
- The equation for Tristan is y = 12.5x
- The equation for Keith is y = 10x.
