Answer:

BC=11

Step-by-step explanation:

we need to find BC

and we  know that

AB= x+2

AC=13

BC=2x+11

A, B and C are collinear

that means that

AB+BC=AC

x+2+2x+11=13

3x+13=13

3x=0

x=0

so BC=2(0)+11

BC=11

A number is greater than 8. The same number is less than 10. The inequalities x > 8 and x < 10 represent the situation.
Semenov [28]

Answer:

There are infinite solutions because there is always another number between any two numbers.

Step-by-step explanation:

Pick any number (including decimal) add an extra decimal after the smallest one and then you have a number between them. E.g.

1.234 and 2.987

1.2341, 1.2342, 1.2343, ... are all between them

List the following numbers in order from least to greatest. a) 3.5× 10/3 B) 3.5× 10-2 C) 5.3 × 10/3
Crazy boy [7]

Answer:

3.5*10^{-2}, 3.5*10^3, 5.3*10^3

B, A, C

Step-by-step explanation:

This is scientific notation. The numbers 3.5 * 10^3\\3.5 *10^{-2}\\5.3 * 10^3 can be ordered least to greatest by looking at their digits and exponents. Since a -2 as an exponent is present, this means this is a small decimal and is the least. 3.5 and 5.3 have the same exponent of 3 but 5.3 is greater than 3.5 so its the greatest. The order is

3.5*10^{-2}, 3.5*10^3, 5.3*10^3

135 = 9x

Divide both sides by 9;

Help Please. Can't seem to understand how to do this. I have tried and watch over 5 videos. Can't seem to get it.​
Snezhnost [94]

Answer:

The solutions are the following:

  • z=2(cos(π6)+isin(π6))=√3+12i

  • z=2(cos(2π3)+isin(2π3))=−1+i√3

  • z=2(cos(7π6)+isin(7π6))=−√3−12i

  • z=2(cos(5π3)+isin(5π3))=1−i√3
