Answer:
Option D
Step-by-step explanation:
If the whole grid is considered to be 1,
Each small grid will value = 
There are 72 shaded grids which represent the hundreds = 0.72
When these grids have been divided into 9 equal rows, number of grids in each row = 8
And the value of 8 grids in each row = 0.01 × 8 = 0.08
So the equation is,
0.72 ÷ 9 = 0.08
Therefore, equation represented by the model will be Option (D).
Answer:
2st
Step-by-step explanation:
because only 34 can be divided by 17 and there arent enough of s and ts
Answer:
s=16t
Step-by-step explanation:
There's not much to explain here. s is the number of miles, t is number of hours elapsed, and for each hour he moves 16 miles so that's where 16 comes from.
Answer:
Simplified expression: 4b + 4c - 5
Perimeter: 27
Step-by-step explanation:
To find the perimeter, we add the lengths of the sides of the quadrilateral, so 2b + 4b - 5 + 3c - 2b + c, which simplifies to 4b + 4c - 5.
Plugging in b = 5 an c = 3, we get 4*5 + 4*3 - 5, which gets us 27.
