4. In which step below does a mistake first appear in simplifying the
expression 0.5(-8x+4)-4(x+5)+7(x-3)?
Step1: - 4x + 2 - 4(x + 5) + 7(x - 3)
Step 2: -4x + 2 - 4x + 5 + 7(x - 3)
Step 3: -4x + 2 - 4x + 5 + 7x - 21
Step 4: -*-14
A. Step1
B. Step 2
C. Step 3
D. Step 4

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

School has 204 sixth grade students. if the sixth grade is 30% of the total school, how many students are in the middle school?

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
