30 ft. tall. You must find the ratios and compare. 2/20=3/x The best way I know to do this is to cross multiply. 2 times x and 20 times 3. So, 2x= 60. Divide by 2 and you get x =30. The height of the tree would be 30 ft. You could also find the proportion. 20/2= 10, so the height,x, over 3 would be equal to 10. 3 times 10 is equal to 30.
Answer:
137 + x <= 170
Step-by-step explanation:
The following inequality will describe this scenario.
137 + x <= 170
the variable x in this scenario represents the total number of cars that you will purchase. This number is added to the number of toy cars that you already own which is 137. As long as this sum is less than or equal to 170 then your storage case will hold them.
Step 1: multiply both sides of the equation by d. d (-3) + 4ad = 2r. Step 2: subtract d(-3) from both sides. 4ad = 2r - d (-3). Step 3: multiply two factors together. Multiply - 1 and -3 to get 3. Step 4: the equation is in standard form. 4da = 2r + 3d. Step 5: undo multiplication by dividing both sides by one factor. Divide both sides by 4d. 4da/ 4d = 2r + 3d/ 4d. Step 6: undo multiplication. Dividing by 4d undoes the multiplication by 4d. a = 2r + 3d/ 4d. Last step, step 7: divide 2r + 3d by 4d. a = r/2d + 3/4. So, a = r/2d + 3/4, d ≠ 0.
