The maple tree that is 95 centimeters tall is growing 9 centimeters per month, whereas the oak tree that is 99 centimeters tall is growing 7 centimeters per month. In a few months, the two trees will be the same height. What will that height be? How long will that take?The two trees will both be ◻ centimeters tall in ◻ months.
Q. Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.Molly has been planting young trees in his garden. The maple tree that is 95 centimeters tall is growing 9 centimeters per month, whereas the oak tree that is 99 centimeters tall is growing 7 centimeters per month. In a few months, the two trees will be the same height. What will that height be? How long will that take?The two trees will both be ◻ centimeters tall in ◻ months.
Maple Tree Equation: Let x represent the number of months, and y represent the height of the trees in centimeters. For the maple tree: Initial height: 95 cm Growth rate per month: 9 cm/month Equation based on the given information: Height after x months = initial height + (growth rate * number of months) y=9x+95For the maple tree, the equation is: y=9x+95
System of Equations: System of equations: y=9x+95y=7x+99To find when the trees will be the same height, set the two equations equal to each other: 9x+95=7x+99
Solve for x: Solve for x: Subtract 7x from both sides of the equation: 9x+95−7x=7x+99−7x2x+95=99
Isolate x: Subtract 95 from both sides of the equation: 2x+95−95=99−952x=4
Substitute x: Divide both sides by 2 to isolate x: 22x=24x=2So, it will take 2 months for the trees to be the same height.
Substitute x: Divide both sides by 2 to isolate x: 22x=24x=2So, it will take 2 months for the trees to be the same height. Now, find the height y by substituting x=2 into one of the original equations. We can use the maple tree's equation: y=9x+95Substitute 2 for x: 212223So, the trees will both be 24 centimeters tall in 2 months.
