Step-by-step explanation:
Answer:
-8
Step-by-step explanation:
12<-3 (x + 4)
1. distribute to the -3 to the x and 4 and should get
<em><u>-3*x = -3x</u></em>
<em><u>-3*4 = -12</u></em>
<u>12< -3x - 12</u>
2. now you get rid of the common factors which is -12 so add 12 to both sides and should get
-12+12=0
12+12=24
<u>24< -3x</u>
3. to get x by itself you will have to get rid of -3, so how to do that is divide -3 to both side and should get
-3x/-3= x
24/-3= -8
<u>-8<x</u>
I=prt
After one year
I=350×0.05×1=17.5
After two years
I=350×0.05×2=35
After three years
I=350×0.05×3=52.5
After four years
I=350×0.05×4=70
Answer:
x=21, y=2 OR (21, 2)
Step-by-step explanation:
solve using substitution:
-1/3x + 9 = 2/3x -12
9 = x -12 (add 1/3 to both sides)
x =21 (add 12 to both sides)
substitute x into first equation to find y ( y= -1/3x +9)
y = -1/3(21) + 9
y = -7 +9
y= 2
Answer : x = 21, y = 2 OR (21 , 2)
