Answer:
Step-by-step explanation:
23(9x-6) = 4x +10
207x - 138 = 4x +10
203x = 148
x = 148/203
or
3(9x-6) = 4x +10
27x -18 = 4x + 10
27x - 4x = 10 + 18
23x = 28
x= 28/23
Answer:
C
Step-by-step explanation:
3y - 5x = 15 ... A
y = 5/3 * X +15 .... slope 3/5 , y intercept 15
6y - 10x =30
(6y - 10x) /2 = 30 / 2
3y - 5x = 15 ... B
y = 5/3 * x + 15 ..... slope 3/5 , y intercept 15
∴ Answer is C

Answer: 18
Step-by-step explanation:
The least common denominator of 
and 
is going to be a multiple of 9 and 6. Let us list them out:
9: 9, <u>18</u>, 27, 36, 45, 54, 63, 72, 81, 90
6: 6, 12, <u>18</u>, 24, 30, 36, 42, 28, 54, 60
You can see I bolded and underlined 18. Why? This is the first common multiple of 9 and 6 so it is our least common denominator (LCD).
It is 5 times the size of the object
