Answer:
20 students
Step-by-step explanation:
You first have to add the number of students all up and you get 200.Then you do cross multiplication.
40/200 x s/100=
40x100= 4000=
200xs= 200s=
200s/200=
4000/200=
20=
Answer:
Apply the distributive property
2x+2(4)=2x+8
Multiply 2 by 4
2x+8=2x+8
Move all terms containing x to the left and subtract 2x
2x+8-2x=8
Combine the opposite terms
2x+8-2x
Subtract 2x from 2x
0+8=8
8=8
All real number
Step-by-step explanation:
Answer:
A lily costs $7 and a geranium $4.
Step-by-step explanation:
From the question, we can write two equations. let the number of lilies be l and the number of geraniums be g, then:
5
g
+
4
l
=
48
4
g
+
6
l
=
58
Multiply the first equation by 4 and the second by 5, the number of lilies in the other gives:
20
g
+
16
l
=
192
20
g
+
30
l
=
290
Subtract the first equation from the second gives:
14
l
=
98 which dividing by 14 gives l
=
7
Substituting the value l
=
7 in the first equation gives:
5
g
+
28
=
48
Subtract 20 from both sides gives:
5
g
=
20 divide by 5 gives g
=
4
So, a lily costs $7 and a geranium costs $4.
