Answer:
z is equal to 0,4, and -3
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
f(x) - g(x)
= x² - 8 - (4 - x) ← distribute parenthesis by - 1
= x² - 8 - 4 + x ← collect like terms
= x² + x - 12 → A
Answer:
18
Step-by-step explanation:
10/0.5 = 20
20 * 0.9 = 18
Saw A = 150 planks/30 seconds = 5 planks per second
Saw B = 130 planks/ 13 seconds = 10 planks per seconds
5 + 10 = 15 planks per second total
225 planks / 15 planks per second = 15 seconds
Answer: 15 seconds
To solve this problem, first let x=0.933333(repeating). Then, you want to multiply both sides by 10 to get 10x = 9.33333 (repeating). Next, take equation 2 and minus equation 1 from it giving you 9x = 8.4. Finally, multiply both sides by 10 and you will get 90x = 84. Divide both sides by 90 giving x=84/90. Answer is 84/90. 84/90 can reduce to 14/15.
