Answer:
Option A
Step-by-step explanation:
If the length is twice as long as the width (14 ft), that makes it 28 ft. (14 x 2=28)
14 ft x 28 ft = 392 square feet
First you can either substitute or elimination.
So what I did was (2) -6x+2y=16 -------> -12x+4y=32
(-3) -4x+y=9 -------------------------------------> 12x-3y= -27
which would come to y=5 and if you put it back in both equations which would make x= -1
Answer:
276
Step-by-step explanation:
∆y = 2y3
∆2 = 2(2)3 = 16
∆5 = 2(5)3 = 250
∆2 + ∆5 = 250 + 16 = 276
Answer:
9 plants
Step-by-step explanation:
Since we are trying to find the number of plants that are shorter than 9 inches, we will look at the plants that are 2, 3, 4, 5, 6, 7, and 8 inches tall.
Each x counts as a plant
# of 2 inch plants: 1
# of 3 inch plants: 1
# of 4 inch plants: 4
# of 5 inch plants: 1
# of 6 inch plants: 1
# of 7 inch plants: 1
# of 8 inch plants: 0
Add up the number of plants:
1 + 1 + 4 + 1 + 1 + 1 + 0 = 9
Answer:
9 plants
Hope this helps!
The answer is .75 because this is a proportion problem so cm over miles is 1 over 2 equals x over 1.5 you cross multiply and get 2x=1.5 and divide both sides by 2 and you get x=.75
