Answer:
x/2 + 21 = 36
First we get rid of constants to isolate the variable.
In order to do that we must do the inverse operation.
Inverse operation of addition is subtraction.
-21 -21(subtracting 21 from both sides, whatever we do to the left side we do it to the right side too)
x/2 = 15
inverse property of division is multiplication
x2 x2
X = 30

Answer:
1 1/4 cups of flour
Step-by-step explanation:
First find the amount for 1 serving.
So you divide the amount of 1 1/2 or 1.50 by 4
1.50/4=.375
Now do .375*7= 2.625 cups of flour
Now you need to subtract the amount you already have which is 4 cups.
2.625-1.50= 1 1/4 cups of flour is what you need left
3127^173 ≡ 7^173 mod 10
Now - let's look at the powers of 7 mod 10:
7^1 = 7 mod 10
7^2 = 49 ≡ 9 mod 10
7^3 ≡ 3 mod 10
7^4 ≡ 1 mod 10
And this cycle repeats. So
7^173 ≡ 7^1 ≡ 7 mod 10
The last digit is 7.
