B. 21 Bo; 23 Erica
C. 16 Bo; 28 Erica
D. 19 Bo; 25 Erica
Answer: D. 19 Bo; 25 Erica
Step-by-step explanation:
Let x represent the number of yoga classes that Bo teaches in a week.
Let y represent the number of yoga classes that Erica teaches in a week.
Between the two of them, they teach 44 yoga classes each week. This means that
x + y = 44 - - - - - - - - - - -1
If Erica teaches 13 fewer than twice as many as Bo, it means that
y = 2x - 13
Substituting y = 2x - 13 into equation 1, it becomes
x + 2x - 13 = 44
3x = 44 + 13 = 57
x = 57/3 = 19
y = 2x - 13 = 2 × 19 - 13
y = 25

Answer:
3/10
Step-by-step explanation:
(3/8)/(1 1/4) = (3/8)/(5/4) = (3/8)/(10/8) = 3/10
The quotient for the given fractions is .
The given fractions are and .
Dividing fractions is nothing but multiplying the fractions by reversing one of the two fraction numbers or by writing the reciprocal of one of the fractions. By reciprocal we mean, that if a fraction is given as , then the reciprocal of it will .
Here,
divided by
Therefore, the quotient for the given fractions is .

Answer: y = 3x
Step-by-step explanation: Proportional means that the y-value will always be three times the x-value--
Or whatever the coefficient of x is in this type of equation.
twice a number and four.
The required expression for Nine less than the quotient of twice a number and four gives the equation, y =2x/4 - 9.
An expression Nine less than the quotient of twice a number and four. is to be determined.
The process in mathematics to operate and interpret the function to make the function simple or more understandableis called simplify and the process is called simplification.
The quotient is the result when one value gets divided by some other value.
Using simple arithmetic,
Let the number be x,
A number y is equal to nine less than the quotient of twice of x and four. So,
y = quotient of 2x and four - 9
y = 2x/4 - 9
Thus, the required expression for Nine less than the quotient of twice a number and four gives the equation, y =2x/4 - 9.

Answer:
-1
Step-by-step explanation:
Twice a number of 4 equals 8
4×2=8
less than 9 of the quotient (answer) of twice a number of 4, is -1
8-9= -1
