If x is fish, y is octopi, and z is crabs, then you would have to know the numbers.
Then your answer would be c. 30x+80y-15z.
Because x=+30, y=+80, and z=-15.
I hope that helps. If you need any further help on this problem just ask.
-1/2 = -3/6
-3/6 + 1/6 = -2/6
-2/6 = -1/3
-1/3 is your answer
hope this helps
Answer:
12 R 147
Step-by-step explanation:
FOIL and PEMDAS are both ways to solve mathematical equations.
<u>FOIL</u><u />
First
Outside
Inside
Last
<u>PEMDAS
</u>Parenthesis
Exponents
Multiplication &
Division
Addition &
S<u />ubtraction
FOIL is usually used to solve equations in two sets of parenthesis, for example:
(23+x)(5-4x)
PEMDAS is used to solve multiple-operation equations, such as:
5 x 4 + 6 - 2 x 7
Whew, hope this helped :D
Answer:
B, C, F
Step-by-step explanation:
B- has different lengths for each side and different angles
C-has different lengths for each side and different angles
F-has different lengths for each side and different angles
Non congruent triangles means if shape is reflected or rotated they would not look the same. Congruent triangles have same equal length and angles are equal in measure.
