x=-9
Answer:
D
Step-by-step explanation:
Let's solve your equation step-by-step.
75+50x=25+70x
Step 1: Simplify both sides of the equation.
50x+75=70x+25
Step 2: Subtract 70x from both sides.
50x+75−70x=70x+25−70x
−20x+75=25
Step 3: Subtract 75 from both sides.
−20x+75−75=25−75
−20x=−50
Step 4: Divide both sides by -20.
−20x
−20
=
−50
−20
x= 5/2
Answer:
<em>Gardener will need 4 more plants.</em>
Step-by-step explanation:
Gardener has 780 plants and wants to plant them in an array of n rows and n columns.
The number of plants needed to do that is:

He actually has 780 plants, thus it should occur:

Taking the square root:
n=27.9
Since n needs to be an integer, we round up n to get
n=28
But
, 4 more than the actual number of plants, thus:
Gardener will need 4 more plants.
Note: There are other possible results for n. If we set n=29, then
and Gardener would need 841-780=61 more plants, but the question asked for the minimum number of plants.
Cost = (3,500) * (1.04)^years
Cost = (3,500) * (1.04)^4
