Step-by-step explanation:
4 1/2 < 1.2x
4.5 < 1.2x
4.5/1.2 < x
3.75 < x
3 3/4 < x
Option 2 is the correct answer
Answer:
C
Step-by-step explanation:
Step-by-step explanation:
x/ 3 = 2 / 9
Cross multiply
9x = 6
x = 6 / 9
x = 2 / 3
Answer:
B = 3y, D = 27, C = 9y
Step-by-step explanation:
Since the top side is equal to y + 9, we can find the areas really easily.
B is equal to 3*y, which is 3y.
D is equal to 3*9, which is 27.
C is equal to y*9, which is 9y.
Cheers!
Answer:
Neither of the students are correct.
Step-by-step explanation:
Sarah:
P = 3x + x +7 + 3x + x +7 ..... this first step is correct
= 6x + 14 .... this step is incorrect, Sarah forgot to add the other 2 xs
John:
P = 2(x + 7) + 2(3x)
= 2x + 7 + 6x .... this step is incorrect, John forgot to distribute the 2 to the 7
= 8x + 7 .... incorrect because of the previous step
The answer should've been 8x + 14.
