Really struggling with a quiz today and I can't seem to figure out any of the answers. Here's all the questions, if anyone can help that'd be great! It's due at 3pm PST 9/30/22 and I have a class 30 minutes before then. (Screenshot provided is for the last question)
Question 1: How can you represent the following expression? Hint: There are two answers. 7 to the power of -3
Answers: -343, 1/7x7x7, (-7)*(-7)*(-7), -21, 1/343, 7*(-3)
Question 2: Solve this expression using order of operations. 1/2 (6-2*(-3))+2- 20/4
Question 3: Simplify the following exponent expression (4 to the power of 7 over 4 to the power of 3). What is the exponent form AND the final answer? (Choose TWO)
Answers: 256, 4 to the power of 10, 4 to the power of 4, 16
Question 4: Maverick solved the two step equation. Where is his mistake?
-3y - 6 = 18
1. -3y = 12
2. 4 = -4
Answers: Step one, subtracting 6 was wrong.
Step two, dividing by -3 was wrong.
No mistakes were made.
Question 5: What is the rule for exponents when multiplying same bases? 5 by the power of two multiplied by 5 to the power of 4
Answers: Multiply the exponents 5 to the power of 8
Add the exponents 5 to the power of 6
Question 6: What's the first step in this multi-step problem? x/4 - 33 = -8
Answers:
dividing by 4 on both sides
adding 33 to both sides
multiplying by 4 on both sides
subtracting 33 to both sides
Question 7: What's the first step in this multi-step problem? x/3 - 15 = -5
Answers: 1/3 (x/3) - 15 = -5 (1/3)
x/3 - 15 + 15 = -5 + 15
Question 8: Combine like terms.
-5x + y - 2z + 8z - y - 2x
Question 9: Put the steps to this multi-step equation in order. -2y + 144 = 28y
Steps: 144/40 = 40y/40
-12y + 12y + 144 = 28y + 12y
144 = 40y
3.6 = y
Question 10: What terms are "like" in the following equation? Hint: There are TWO correct choices. || 3a - 5b = 5a + 3b
Answers: 3a, 3b
3a, - 5a
-5b, 3b
5b - 5a
Question 11: Solve the multi-step equation using distributive property.
2(3x - 5) = 4x + 2
Question 12 (last one): What is the lowest common denominator you would multiply both sides of the equation by to eliminate the denominators?
