Step-by-step explanation: There you go btw wanna trade r o b l o x acc.
Answer:
Step-by-step explanation:
x - the temperature
y - the number of people
the temperature is between 75 degrees and 110 degrees:
75 < x < 110
the room for 50 people:
0 < y ≤ 50
Answer:
No sorry I don't
I did that last year and I don't remember how
Step-by-step explanation:
Volume is given by:
V=(base area)×(height)
base area=bh
where:
b=base=8.5 cm
h=height= 4 cm
thus
base area=8.5×4=34 cm²
Thus the volume will be:
V=34×14
V=476 cm³
Step-by-step explanation:
This is a word problem that we must translate to mathematical expression before we can solve.
let the individual saving be the first letters of the names
Jada= J
Lin= L
Elena= E
1. Jada saved $20 less than Lin
J=L-20
2. Lin saved 3 times as much money as Elena
L= 3E
3. Hence Elena saved
E
Together they saved $120.
hence
(L-20)+3E+E= 120
L-20+3E+E= 120
collecting like terms we hav
L+4E=120+20
L+4E= 140
but we know that L= 3E
3E+4E= 140
7E= 140
divide both sides by 7 we have
E= 140/7
E= $20
This means Elena saves $70
also L= 3E
L= 3*20
L= $60
this means that Lean saved $60
also J=L-20
J= 60-20
J= $40
This means that Jada saved $40
