13 × 9w = 13 × 
117w = 5w - 6 + 13
117w = 5w + 7
117w - 5w = 5w - 5w + 7
112w = 7
112w ÷ 112 = 7 ÷ 112

Answer:
5/8
Step-by-step explanation:
Find the common ratio by dividing one of the numbers in the sequence by the previous one:
480/768
= 0.625
Convert this to a fraction:
0.625
= 5/8
So, the common ratio is 5/8
Answer:
C, Plus or minus 3
Step-by-step explanation:
to solve 3x² - 27 = 0, we want to get the x by itself, so lets add 27 to both sides.
3x² = 27 < divide both sides by 3 to get x alone
3x²/2 =x²
27/3 = 9
x² = 9 < we can use the square-root property and square both sides of the equation to get x alone. we use the ± because there are 2 possible solutions to a square rooted number
√x² = x
√9 = 3
x = ±3
looking at our answer choices, the correct answer is C
Answer:
B. 0.0625
Step-by-step explanation:
Given that the program has graduated and undergraduates enrolled,
Let the probability of selecting a graduate = p(g)
And the probability of selecting an undergraduate = p(u)
p(g) = p(u) = 50% = 0.5
Therefore,
Probability of selecting 4 students who are undergraduates
=p(u)p(u)p(u)p(u)
= 0.5 × 0.5 × 0.5 × 0.5
= 0.0625
The right option is B
