Answer:
13.4
Step-by-step explanation:
1/3 * 3x + 5.2y
1/3 * 3(3) + 5.2(2)
1/27 + 10.4
Answer:
15
Step-by-step explanation:
var a = 3
then a= 3
var b = 5
then b = 5
a ( a new variable ) = a * b = 3 * 5
X= -2
put x+3=-2x-3
+3. +3
x+6=-2x
-x. -x
6= -3x
/3. /3
x=-2
(a,7) lies on the equation of 5x-y=8, that means we solve for x when y=7.
5x-(7)=8
5x=8+7=15
x=3
=>
a=3
