12 is B. You because the graphs slope is 1. 13 is A 7 I think.
Answer:
It's not correct
Because
Ratio is the comparison of two quantities having same units
So this ratio can't be taken
Answer:
Step-by-step explanation:
for the first one it's (x + 5) x (x - 7)
second one it's (x + 5) x (x + 7)
third one is (x - 5) x ( x + 7)
fourth one is (x -5) x (x - 7)
thats the answer
Answer:
Step-by-step explanation:
x^3 = 1/8
Taking the cube of both side
x^3 = 1/(2)^3
(x)^3 = (1/2)^3
Eliminate ^3 from both sides
x = 1/2
Answer:
20n
Step-by-step explanation:
One pretzel has 20 calories. Write an algebraic expression for the total number of calories in n pretzels.
1 pretzel = 20 calories
n pretzel = x
Cross Multiply
x × 1 pretzel = n pretzel × 20 calories
x = n pretzel × 20 calories/1 pretzel
x = 20 n
Therefore, an algebraic expression for the total number of calories in n pretzels = 20n
