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.
Answer:
commutative property
Step-by-step explanation:
commutative property
The value of x will be obtained as follows:
1331x^4-216=0
1331x^4=216
divide through by 1331
x^4=216/1331
x=(216/1331)^(1/4)
x=(6^3/11^3)^(1/4)
x=(6/11)^(3/4)

Answer:
1 = t/45 + t/105
Step-by-step explanation:
Greg's father mow a lawn in 45 minutes that means that he mow in a rate of 1/45
Greg mow a lawn in 1 hour 45 minutes (105 minutes) that means that he mow in a rate of 1/105
If they mow a lawn in t minutes that means the rate is 1/t
Then, the rate in which they mow a lawn has to be equal to the sum of the rate individually as follows
1/t = 1/45 + 1/105
1 = t/45 + t/105
