The ratio 2:11 means for every 3 apple trees they will plant 11 pear trees.
They are planting 150 apple trees. Divide total apple trees by the ratio: 150/3 = 50
Multiply that by the ratio of pear trees:
50 x 11 = 550
They need to plant 550 pear trees.
Answer:
D. -3x+3y
Step-by-step explanation:
Start by distributing the -3 to each term in the parentheses:
-3(x)+(-3)(-y)
Here are some multiplication sign rules that will make this problem easier:
- - make a +
- + make a -
+ - make a -
+ + make a +
-3x+3y (note that since both 3 and y are negative, they make a positive)
If its not the 1st one, try the last one.
