Answer: y = 40 + 15 + .25x , y = 45 + .35x
Step-by-step explanation: What is your question? if your looking to put them into forms then here it is
Answer:
for six you got to get rid of the x's first the you it how u normally would
Step-by-step explanation:
The are would be 25
and we could make 3 squares. 75
5inches will be left over.
50 + .4x = 70 + .3x
.4x = .3x + 20
.1x = 20
x = 200
Let x be the number of miles.
They have to drive 200 miles.
Let a be the number of trumpet players
Let b be the number of saxophone players
---------------------
(1) a = b-10
(2) b =3a
----------------
Substitute
(2) into (1)
(1) a =3a-10
(1) 2a =10
(1) a = 5and
(2) b = 3(5)(2)
b = 15
------------------
There are 5 trumpet players and 15 saxophone player
