Answer:
x = 15
Step-by-step explanation:
MN:RS
18:30
MQ:RU
Known:Known
QP:TU
15:Known
NP:ST
x:25
18/30 = x/25
30x = 18*25
30x = 450
x = 15
Consecutive even numbers are represented like this
even numbers are represented like this 2x=even
consecutive even numbers are 2 apart so
the numbers are 2x, 2x+2, 2x+4
so
2x+2x+2+2x+4=162
add like terms
6x+6=162
subtract 6 from both sdies
156=6x
divide both sdies by 6
26=x
the first even number=2x so
26 ties 2=52
second number=2x+2=52+2=54
third number=2x+4=52+4=56
the numbers are 52,54,56
Answer:
7
Step-by-step explanation:
On a military clock the difference between a number and it's opposite is always 12
19 - x = 12
19 - 12 = x
7 = x
21 a² - 57 a + 30 =
= 3 ( 7 a² - 19 a + 10 ) =
= 3 · 7 · ( a - 5/7 ) · ( a - 2 ) =
= 3 ( 7 a - 5 ) ( a - 2 )
