Is 10x-5=8x-2x + 7 -2 equivalent?

Mathematics

yan [13]3 years ago

Answer:

2.5

Step-by-step explanation:

Lets simpify one side first

8x - 2x + 7 +2

8-2 = 6

so 6x

7-2 = 5

6x+9

10x - 5 = 6x +5

(You add 5 due to it being negative on the other side)

+5             +5

10x= 6x +10

-6x    -6x

4x = 10

Divide each side by 4

x = 2.5 or 10/4 or 5/2

Answer: No

Step-by-step explanation: To find whether these are equivalent, we first need to simplify the equation on the right.

8x-2x+7-2

8x-2x+5  (work-    7-2 = 5)

6x+5       (work-    8x-2x=6x) These are like terms, so we can subtract them

now that we have simplified, let's write the equations once again.

10x-5=6x+5

they are surely not equivalent

Two days after a biology experiment there was 49 million bacteria present. Four days after the experiment there was 600.25 milli
nataly862011 [7]

Answer:

y=Ae^(1.25t)

Step-by-step explanation:

From the expression  y=Ae^kt

After two days of the experiment, y = 49 million, t=2

After four days of the experiment, y= 600.25 million, t=4

A is the amount of bacteria present at time zero  and t is the time after the experiment (in days)

At t=2 and y =49

 49=Ae^2k…………….. (1)

At t=4 and y = 600.25

600.25=Ae^4k………… (2)

Divide equation (2) by equation (1)

600.25/49=(Ae^4k)/(Ae^2k )

12.25=e^2k

Take natural log of both sides

ln⁡(12.25) =2k

2.505⁡ =2k

k=1.25

The exponential equation that models this situation is y=Ae^(1.25t)

Will factor the express 36xyz + 24xy − 16x by dividing each term by a common fact
sesenic [268]

\\ \bull\tt\longmapsto 36xyz+24xy-16x

  • Divide by 4

\\ \bull\tt\longmapsto \dfrac{36xyz}{4}+\dfrac{24xy}{4}-\dfrac{16x}{4}

\\ \bull\tt\longmapsto 9xyz+6xy-4x

  • Divide by x

\\ \bull\tt\longmapsto \dfrac{9xyz}{x}+\dfrac{6xy}{x}-\dfrac{4x}{x}

\\ \bull\tt\longmapsto 9yz+6y-4

How many degrees is StartFraction 15 Over 16 EndFraction pi radians? 84.375° 93.75° 168.75° 337.5°
Leno4ka [110]

Answer:

x = 168.75°

Step-by-step explanation:

<u>Angle Measurement Units</u>

To convert from different units for angle measurements, we have to recall that:

180 degrees = π radians

If we are given the angle in degrees, multiply by π/180 to convert it to radians.

If the angle is given in radians, multiply by 180/π to convert to degrees.

We are given the angle:

\displaystyle x=\frac{15}{16}\pi

Multiplying by 180/π:

\displaystyle x=\frac{15}{16}\pi\cdot \frac{180}{\pi}

Simplifying:

\displaystyle x=\frac{15*180}{16}

x = 168.75°

What is the length of the midsegment of this trapezoid? Enter your answer in the box. units Trapezoid A B C D on the coordinate
emmainna [20.7K]

9514 1404 393

Answer:

  9 units

Step-by-step explanation:

The top base has a length that is the difference between the x-coordinates of points A and B:

  0 -(-11) = 11

The bottom base has a length that is the difference between the x-coordinates of points C and D:

  -1 -(-8) = 7

The mid-segment has a length that is the average of the base lengths:

  (11 +7)/2 = 18/2= 9 . . . units; midsegment length
