Answer: choice D) minus 1 and 2 over 4
(which is the same as writing $-1 \frac{2}{4}$ or writing -1 & 2/4)

-----------------------------

The point P is exactly halfway between 1 and 2. So it's at the point 1&1/2 or 1&2/4
1/2 = 2/4

Flip the point from positive to negative and you get the final answer to be -1 & 2/4

Answer:

A. 84x - 16y - 10.6

Explanation:

$\sf \rightarrow 2(14x-3y+28x+12.2-5y-17.5)$

$\sf \rightarrow 2 (42x-8y-5.3)$

apply distributive method: a(b + c) = ab + ac

$\sf \rightarrow 2 (42x) -2(8y)-2(5.3)$

$\sf \rightarrow 84x -16y-10.6$

For the pair of supply-and-demand equations, where x represents the quantity demanded in units of 1000 and p is the unit price i

Liono4ka [1.6K]

Answer:

7 and 6 respectively

Step-by-step explanation:

Firstly, we have to solve the equations simultaneously.

2x + 7p = 56

3x - 11p = -45

Multiply equation I by 3 and ii by 2

6x +21p = 168

6x - 22p = -90

Subtract the second from first to yield:

43p = 258

p = 6

Insert this in equation 1 where we have 2x + 7p = 56

2x + 7(6) =56

2x + 42 = 56

2x = 14 and x = 7

The equilibrium price is 6 and the equilibrium quantity is 7

Audrey has $111 to spend on a tennis racket and lessons. The racket costs $55 and the lessons cost $14 per hour. Define a variab

Mnenie [13.5K]

Answer:

Audrey can afford 4 hours of lesson.

Step-by-step explanation:

Given that:

Amount Audrey has to spend = $111

Cost of racket = $55

Cost per lesson = $14

Let,

y be the total cost

x be the number of hours

According to given statement;

y = 14x + 55

111 = 14x + 55

111 - 55 = 14x

14x = 56

Dividing both sides by 14

$\frac{14x}{14}=\frac{56}{14}\\x=4$

Hence,

Audrey can afford 4 hours of lesson.
