Answer:
- <u><em>The cost of one rose bush is $ 9 and the cost on one bunch pf ornamental grass is $ 8.</em></u>
Explanation:
Name the variables and build a system of two equations with two unknowns.
<u>1. Variable r</u>: cost of one rose bush
<u>2. Variable g</u>: cost of one bunch of ornamental grass.
<u>3. First equation</u>:
- Shreya spent $68 on 4 rose bushes and 4 bunches of ornamental grass.
4r + 4g = 68
<u>4. Second equation</u>:
- Beth spent $115 on 11 rose bushes and 2 bunches of ornaments grass.
<u>5. System of equations</u>:
- 11r + 2g = 115 equation 2
<u>6. Solve the system</u>
a) Divide the equation 1 by 2:
- 11r + 2g = 115 equation 2
b) Subtract equation 1a from equation 2:
c) Substitute the value of r into the equation 1a:
<u>7. Conclusion</u>:
The cost of one rose bush is $ 9 and the cost on one bunch pf ornamental grass is $ 8.
Answer:
I think is is 2(x+12)
Step-by-step explanation:
two times x and 12, so 2(x+12)
Answer:
15
you can use the equation p = 2l+2w to find the width of the rectangle
Step-by-step explanation:
perimeter of a rectange p = 2l+2w
l = length
w = width
p = perimeter
it tells you the perimeter is 50 so p=50
it also tells you the length is 10
solve for w (width)
50 = 2(10)+2w
50 = 20+2w
30 = 2w
15 = w
width is 15
The dimensions are 16sqrt{5}-10 and 16sqrt{5}+10
