Answer:
x = 2.95
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
0.45 plus 9x equals 27
0.45 + 9x = 27
<u>Step 2: Solve for x</u>
0.45 + 9x - 0.45 = 27 - 0.45
9x / 9 = 26.55 / 9
x = 2.95
Answer: x = 2.95
Answer:
2x-3y=9 and 4x-6y=30
Step-by-step explanation:
hello :
note y=(2/3)x+5 no y=23x+5
2/3 is the slope....... all lines parallel to this line has same slope.
1) 2x-3y=9 means : 3y = 2x-9 divide by 3 : y=(2/3)x-3..same slope.
2) 4x-6y=30 means : 6y= 4x-30 divide by 6 : y=(4/6)x -30/6
but 4/6 = 2/3 so : y=(2/3)x-5..same slope.
