SOMEONE PLEASE HELP ME ;( Your teacher asked your class to describe a real-world situation in which a y-intercept is 100 and the slope is 5. Your partner gave thefollowing description: My younger brother originally had 100 small building blocks, but he has lost 5 of them every month since. What mistake did your partner make? Describe a real-world situation that does match the situation.

Answers

Okay so your partner describes a situation that has a slope of NEGATIVE 5, not positive 5 as your teacher asked.
Instead, your younger brother could have started with 100 and GAINED 5 every month, instead of losing 5.

Peggy completed 5/6 of the math homework and Al completed 4/5 of the math homework. Did Peggy or Al complete more of the math homework?

Answers

Answer:

Peggy completed more of the math homework than Al

Step-by-step explanation:

we have

Peggy completed $5/6$ of the math homework

Al completed $4/5$ of the math homework

we know that

In order to be able to compare fractions more easily it is recommended that both have the same denominator

Multiply $5/6$ by $5/5$

$5/6(5/5)=25/30$

Multiply $4/5$ by $6/6$

$4/5(6/6)=24/30$

$25/30> 24/30$

therefore

Peggy completed more of the math homework than Al

Peggy 5/6 x 5 = 25/30
Al 4/5 x 6 = 24/30

Peggy completed more of the math homework

What is the best way to classify each equation? 22-3x+7x=4(x+5) ,6(2x-3=3(3-5), 6x-14=2(3x-7), 6x+3(x-4)=8(x-3)

Answers

1. 22 - 3x + 7x = 4(x + 5)
   22 - 3x + 7x = 4x + 20
      +3x +3x   +3x
   22 + 10x = 7x + 20
      -7x   -7x
   22 + 3x = 20
      -22    -22
   3x = -2
      3 3
   x = -2/3

2. 6(2x - 3) = 3(3 - 5)
    12x - 18 = 3(-2)
    12x - 18 = -6
   +18   +18
   12x = 12
      12    12
   x = 1

3. 6x - 14 = 2(3x - 7)
    6x - 14 = -3x
    6x - 14 = 2(-7)
    6x - 14 = -14
   +14   +14
   6x = 0
      6    6
   x = 0

4. 6x + 3(x - 4) = 8(x - 3)
    6x + 3x - 12 = 8x - 24
          9x - 12 = 8x - 24
      -8x     -8x
      x - 12 = -24
   +12    +12
           x = -12
