Answer:
z = -4
Step-by-step explanation:
-5/2 = 3z/4 + 1/2
-10 = 3z + 2
-10 - 3z = 2
-3z = 12
12/-3 = -4
z = -4
B+B=2
assuming that B is 1 I will say that 4 is C.
4+1*2= 10 is your answer.
Answer:
Step-by-step explanation:
f(-9)=2(-9)²+5(-9)+20
= 162-45+20
= 137
Rewrite the length as an improper fraction.
21 7/8 = 175/8
Write the quantity of stamps as a fraction: 25/1
Divide length by number of stamps:
175/8 / 25/1
When dividing by a fraction change the sign to multiplication and flip the second fraction over:
175/8 x 1/25.
Now multiply numerators and then denominators:
(175 x1) / (8x 25) = 175/200
Simplify to 7/8
Each stamp is 7/8 inches long
