Answer:
2.4cm by 5.6cm
Step-by-step explanation:
scale factor is 5
measurements of the image 12cm by
28cm
scale factor=image dimensions÷object dimensions
object dimensions=image dimensions÷scale factor
=28÷5
=5.6cm
=12÷5
=2.4cm
=2.4cm by 5.6cm
Answer: x = -5
Step-by-step explanation:
First convert 3/4 to decimal= 0.75
0.75 (8x - 4) = 7x + 2
6x - 3 = 7x + 2
Transpose 7x from right hand side to the left hand side
6x - 7x = 2 + 3
-x = 5
x = -5
I hope this helps.
Answer:
3.625
Step-by-step explanation:

Answer:
- 3x + 4 = 9x -6
- 3x + 4 = 3x + 5
- 9x + 6 = 9x + 6
Step-by-step explanation:
Let x is the variable in each type of equation
1/ an equation that has one solution:
3x + 4 = 9x -6
<=> 9x - 3x = 4+6
<=> 6x = 10
<=> x = 
2/ an equation that has no solution:
3x + 4 = 3x + 5
<=> 3x - 3x = 5-4
<=> 0 = 1 impossible
3/ an equation that has infinite many solutions:
9x + 6 = 9x + 6
<=> 9x - 9x = 6 -6
<=> 0 = 0 (obvious) no matter what we put in for x
Hope it will find you well.
