BRAINLIEST IS ON THE LINE

8/15

-3

2 1/7

-10

Step-by-step explanation:

A. 8/15

B. 36/-12 = 3/-1 (-3)

C. -15/-7 (15/7)

D. -30/3 = -10/1 (-10)

Step-by-step explanation:

To find the quotient of two fractions, change the equation from division to multiplication.

Each time you divide fractions, remember this:

SAME, CHANGE, RECIPROCAL (FLIP)

For example, 2/5 ÷ 3/4

SAME: Keep 2/5 as it is.

CHANGE: Change the division to a multiplication sign.

RECIPROCAL (FLIP): Switch the numerator and denominator; 3/4 would become 4/3.

2/5 x 4/3

(Multiply the numerators and denominators).

2/5 x 4/3 = 8/15.

Now, repeat this with other equations.

9/4 ÷ -3/4

9/4 x 4/-3 = 36/-12 = 3/-1 (-3)

-5/7 ÷ -1/3

-5/7 x 3/-1 = -15/-7 = (15/7)

-5/3 ÷ 1/6

-5/3 x 6/1 = -30/3 = -10/1 (-10)

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
