Suzanne is landscaping her front yard. she made two trips to bring all the plants home. on the first trip she bought 8 flowers and 9 shrubs for $129. on the second trip she bought 12 flowers and 6 more shrubs for $126. if she bought the same kind of flower and shrub each time, what is the price, in dollars, of each shrub? (use only the digits 0-9 and a decimal point, if needed, to enter a number.)

$9

Step-by-step explanation:

Let price of flowers be f

and

let price of shrubs be s

On first trip, we can write:

8f + 9s = 129

On 2nd trip, we can write:

12f + 6s = 126

Since we need to find price of shrubs, we can solve the first equation for f and put it into 2nd equation and solve:

8f + 9s = 129

8f = 129 - 9s

f = (129 - 9s)/8

Now putting in 2nd, we solve for "s":

Hence

the price of each shrub is $9

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
