x - 26 + 26 = -45 + 26
x = -19
A gardener is planting two types of trees: •Tree A is 36 inches tall and grows at a rate of 12 inches per year. •Tree B is 48 in
2 answers:
Answer:
c) 12x + 36 = 10x + 48
Step-by-step explanation:
We are given the following information:
Height of tree A = 36 inches
Growth rate of tree A = 12 inches per year.
Height of tree B = 48 inches
Growth rate of tree B = 10 inches per year.
If x is the number of years after which the tree will have same height.
Height of tree A in x years =
Height of tree B in x years =
Equating these equation,
Hence, option c) represents the correct equation such that the tress will have same height in x years.

We have been given that Sterre charges $35 to file tax returns, but files for free if she only needs the easiest form. Also, she donates $2 to clean water projects per tax return she files.
Further we know that Sterre charged $7,245 and made a donation of $1,242 this year for the tax returns she filed.
Let x be the number of free income tax returns and y be the number of $35 income tax returns.
Therefore, we can set up:
Since she donates $2 for each return that she files, therefore, we can set up:
Therefore,
Sterre filed 414 tax returns for free and filed 207 tax returns for $35.
