Solve the Systems of Equation using Substitution y=x-4 4x - 6y=-16​

Mathematics
1 answer:
Alborosie3 years ago

Answer:

x=20 and y=16

Step-by-step explanation:

4x - 6y= -16

since y=x -4, we substitute it in place of "y"

Then, 4x - 6(x-4) = -16

4x - 6x + 24 = -16

-2x+24= -16

-2x= -16-24

-2x= -40

Divide both sides by -2 then,

x=20

once we get the value of "x" we substitute in place of "y=x-4"

y=20-4

y=16

Advocard [28]
T=8√t
T=temperature
t=time in minutes.
If T=48, we have to calculate the time.

48=8√t
(48)²=(8√t)²
2304=64t
t=2304 / 64=36

svet-max [94.6K]

The percentage of reduction is 17%

<u>Explanation:</u>

Original price = $21

Reduced price = $17.43

Percentage of reduction = ?

Difference in price = $21 - $17.43

                               = $3.57

Percentage of reduction = \frac{difference}{original} X 100

                                         = \frac{3.57}{21} X 100\\\\= 17

Therefore, percentage of reduction is 17%
