I could really use some help pls!

JM= 12.8

Step-by-step explanation:

Pythagorean Theorem.

A^2+B^2=C^2

*C is always the longest length (in this case, JM)

8^2+10^2=C^2

64+100=C^2

C^2=164    *Keep in mind this is C SQUARED, not C. We need to simplify by finding the square root*

C= about 12.8=JM

*Length JL is split in half*

180

step-by-step explanation:

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
