Step-by-step explanation:
1
a.Solution:
-32÷8×2+2+1
=-4×2+2+1
=-8+2+1
=-8+3
=-5
b. Solition:
53×9+109×53
=477+5777
=5300
c. Solution:
-891
d. Solution:
-63×12+12×37
=-756+444
-312
2.
a. Solution:
5y-3+3=-18+3
5y=-15
y=-15/5
y=3
b. Solution:
-3x-9+9=0+9
-3x=9
x=9/-3
x=-3
c. Solution:
4+3-3(z-8-3)=-23-3
4(z-5)=-20
4z-20=-20
4z-20+20=-20+20
4z
z=4
d. Solution:
1-2+2(y-4+2)=5+2
3(y-2)=7
3y-6=7
3y-6+6=7+6
3y=13
y=13/3
y=4.33

Here is the reference No funny stuff XD</u></h2>
Since it is given that 4/5 mile is equal to 1/2 inch, what we will be looking for how many inches will there be for 1 mile. 5/5 mile = 1 mile.
This is how it would look like.
1/2 inch.... x inch
----- = -----
..4/5 mile ...... 1 mile
Next, we cross multiply:
(1/2)1 = (4/5)x
Then divide both sides by 4/5. so we get
x = 0.025 inch
and that is 1/40 inch. Therefore, 1 mile is 1/40 inch. Hope this helps.

I guess the only way to use subtraction is to take the total area of the grid and subtract it by the total area around the figure. So it since it is a 10 by 10 grid, it would be 100 (since 10*10=100) minus the area around the shape.
