How to solve 6^x-2=1/4

Answers

Answer 1

Answer: you can solve it by take log( ) for both sides
6^x-2= 1/4
(x-2) log(6) = log(1/4)
(x-2) = log(1/4) / (log(6))
x-2= -0.774
x= -0.774 +2
x= 1.226

LEt the unknown number be x

Sum represents the addition of two numbers

Sum of three and a number means the addition of 3 and number x

So the expression become 3+ x

a=3+b. That is a reasonable expression, because a= the sum of 3 and b, an unknown number.

St=18 and s = -4 where could T be located ?

Answers

Answer:

14 or -22

Step-by-step explanation:

st=18

s=-4

-4+18=14

so t can be at 14

or -4-18=-22

t can be at -22

The bases of a circular cylinder are two ___ circles.

Answers

Well,

A cylinder is actually a special type of prism. A prism is a 3-D figure made by taking a simple closed plane curve and translating it across space in a certain direction and for a given distance and then connecting the preimage and the image. A cylinder is just a prism made with a circle.

We know from translations that the image is congruent to the preimage. Thus, the bases of a (circular) cylinder are two congruent circles.

Which is the longest 2 km 25m 2500 cm or 3000 mm

Answers

2km=2 kilometer
kilo=1000 so 2 km=2000m

25m

2500cm
cm=centimeter=1/100 of a meter
so
2500cm=25m

mm=milimeter=1/1000 meter
so
3000mm=3m

so the longets is obviously 2000m or 2km

So,

Let's state everything in terms of meters (m).

The conversion factor between km and m is as follows:
1 km = 1000 m
Therefore, 2 km is 2000 m.

The conversion factor between cm and m is as follows:
100 cm = 1 m
Therefore, 2500 cm is 25 m.

The conversion factor between mm and m is as follows:
1000 mm = 1 m
Therefore, 3000 mm is 3 m.

Here are all the numbers in meters.
2000 m, 25 m, 25 m, 3 m

We can quickly see that 2000 m is the longest distance. It is 2 km.

Solve for X
3ax/5 - 4c = ax/5

Answers

$\frac { 3ax }{ 5 } -4c=\frac { ax }{ 5 }$
First multiply both sides by 5:
$5\cdot (\frac { 3ax }{ 5 } -4c)=5\cdot \frac { ax }{ 5 } \n 3ax-20c=ax$
then take the ax to the other side :
$3ax-20-ax=0$ and simplify:
$2ax-20c=0$ factor:
$2(ax-10c)=0\n ax-10c=0\n ax=10c\n x=\frac { 10c }{ a }$
