Answer:
B = 1320
Step-by-step explanation:
Let A = number of students at Branch A
Let B = number of students at Branch B
If the number of students taking classes at Branch A is 1/4 more than Branch B, then:
If Branch A has 1,650 students, then substitute A = 1650 and solve for B:
2/3 A = 16
The multiplicative inverse is also known as the reciprocal. To solve for the value of A, multiplicative inverse is required.
<span>The multiplicative inverse of 2/3 is 3/2. When you divide a number by a fraction, you first get the reciprocal of the fraction. Then, you multiply the number by the reciprocal of the fraction. </span>
2/3 A = 16
A = 16 / 2/3
A = 16 * 3/2
A = 48 / 2
A = 24
To check:
2/3 A = 16
2/3 (24) = 16
48 / 3 = 16
16 = 16
Answer: d) 255 ≤ f(x) ≤ 340
Step-by-step explanation:
The function
f(x)= 8.5x
represents the amount of money that Steve earns given the number of hours, x, he works.
The dependent variable is the total amount that he earns, f(x) while the independent variable is the number if hours, x that he works. The range is the possible values of the dependent variable that satisfies the equation.
Steve works between 30 and 40 hours per week. This means that
the lowest amount that he earns is 8.5×30 = $255
The highest amount that he earns is 8.5× 40 = 340. Therefore, the range is
255 ≤ f(x) ≤ 340
Answer:
B) 4x + 12
Step-by-step explanation:
If we use the distributive property, multiplying the 4 with each term of the parentheses, it would give the same as
