7h+3s=27.95 subtract 7h from both sides

3s=27.95-7h divide both sides by 3

s=(27.95-7h)/3

Then we are told:

5h+4s=23.4, using s found above makes this equation become:

5h+4(27.95-7h)/3=23.4 multiply both sides by 3

15h+4(27.95-7h=70.2 perform indicated multiplication on left side

15h+111.8-28h=70.2 combine like terms on left side

-13h+111.8=70.2 subtract 111.8 from both sides

-13h=-41.6 divide both sides by -13

h=$3.20

29 mint plants and 29 other herb plants at the garden center. Considering this data, how many of the next 62 herb plants stocked

spin [16.1K]

Answer: 31 mint plants

Step-by-step explanation:

We will have mint plants over total plants:

29/29+29 = 29/58 = 1/2

Now, we will multiply 62 by 1/2 to guess how many mint plants will be stocked.

62* 1/2 = 31

We should expect about 31 plants of the total plants to be mint plants.
