Remember yo can do anything to an equation as long as you do it to both sides
so
remember distributive property
a(b+c)=ab+ac
so first distribute
2(3x)+2(-9)=18x
6x-18=18x
minus 6x both sides
-18=12x
divide both sides by 12
-18/12=x
-9/6=x
-3/2=x
easier way is to first divide both sides by 2
x=-3/2
Answer:
-7 < -5
Step-by-step explanation:
-5 is greater than -7
Answer:
5
Step-by-step explanation:
solve equation 180+92x= 250+78x
A=100°
as 180-140= 40 , 40 x 2 = 80 & 180-80 = 100° = a
11,339,800 is 11,340,000 rounded to the nearest whole number
