X = jane, y = jasmine, z = jocelyn
x + y + z = 56
x = 3z
y = 2z + 2
3z + 2z + 2 + z = 56
6z + 2 = 56
6z = 56 - 2
6z = 54
z = 54/6
z = 9 <==== jocelyn
x = 3z
x = 3(9)
x = 27 <=== jane
y = 2z + 2
y = 2(9) + 2
y = 18 + 2
y = 20 <=== jasmine
Answer:
Sam
30
Step-by-step explanation:
Sam made a mistake when he said
. The steps should have been:

You are supposed to square 5 first before multiplying 2. Sam multiplied by 2 first. The correct answer is 30.
Answer is choice C) 4x^2-3x+9
You list off the terms in a way where the largest exponent term comes first, then the second largest exponent is next, and so forth. Note how the last term 9 is the same as 9x^0. The term 3x is equivalent to 3x^1. So what we really have is 4x^2-3x^1+9x^0. The exponents count down: 2, 1, 0

Step-by-step explanation:
Answer:
No solution
Step-by-step explanation:
You are given the inequality

First, eliminate brackets in left side of the inequality:

Now separate variables and numbers:

So

The last inequality is false (0 is not less than -2), so the initial inequality has no solution.
