1. By combining like terms
2. Same variable = same term, so you can combine them
3. Because 2y - y = 1y , and 1y is the same as y because a y is one y (obviously)
4. 1/2 + 1/2 = 1. A half an x and a half an x makes one whole x, therefore, x
5. No. You solve them like you would a normal equation with like terms. So it would be 3z^2
Hopefully these are right, I’m a bit rusty!
6. 4x
7. 3y
8. y - 4.5
9. 3.5x + 2
10. 4y + 2
11. 7x
12. 2.2w - 0.5
13. 23b + 6.6
14. 3.75x + 1.5
15. 0.8x + 2.1
Good luck, I hope this helped

Step-by-step explanation:
Answer:
Step-by-step explanation:
(10.03 - 10)/(.12/sqrt 100) = 2.5
P(Z > 2.5) = .0062
p-value = .0062. The apples are not within the FDA requirement
Answer:
95 cents per Muffin
Step-by-step explanation:
Set up the long division.
8 | 7 6 0
2. Calculate 76 ÷ 8, which is 9 with a remainder of 4.
9
8 | 7 6 0
7 2
4
3. Bring down 0, so that 40 is large enough to be divided by 8.
9
8 | 7 6 0
7 2
4 0
4. Calculate 40 ÷ 8, which is 5.
9 5
8 | 7 6 0
7 2
4 0
4 0
5. Therefore, 760 ÷ 8 = 95.
Answer:
Step-by-step explanation:
4/5 is less than 1, so multiplying 5/8 by 4/5 results in a product smaller than the two factors.
