Step-by-step explanation:
3(5x - 4) = 2(7x)
=> 15x - 12 = 14x
=> x = 12
<em>By the options given, I would say none of the options are correct!</em>
A = (a+b)/2
2*A = 2*(a+b)/2 ... multiply both sides by 2
2A = a+b
2A-a = a+b-a ... subtract 'a' from both sides to isolate b
2A-a = b
b = 2A-a
Answer: b = 2A-a
Answer:
question 6:
+ 9x + 14 and (x + 2) (x + 7)
question 7:
- 7x + 10 and (x - 2)(x - 5)
question 8:
- 9x + 20 and (x - 4)(x - 5)
question 9:
(x + 1) (x - 17)
- 17x + 1x - 17
- 16x - 17
question 10:
(x - 1) (x + 17)
+ 17x - 1x - 17
+ 16x - 17

Answer:
2/45
Step-by-step explanation:
Note this selection is done without replacement hence after each selection sample size will reduce
Given data
Samples 3 chocolate chip bars,
2 peanut butter bars,
1 lemon bar, and
4 raisin bars
Sample size S= [3+2+1+4]= 10
Probability that first selection is lemon = 1/10
Probability that second selection is raisin = 4/9
Hence the probability that the first bar Iesha selects will be lemon and the second will be raisin= 1/10*4/9
= 4/90= 2/45
