Answer:
The simplest form ratio is 1 : 50000.
Step-by-step explanation:
To find the ratio of 2 cm : 1 km
Firstly, we need to convert both the quantities into the same unit of measurement.
Now 1 km = 1,00,000 cm
So, now we need to find the ratio of 2 cm : 1,00,000 cm
⇒ The required Ratio is
Hence, the simplest form ratio is 1 : 50000
Hey there! :)
7. -4(2z + 6) - 12 = 4
Simplify.
-8z - 24 - 12 = 4
Simplify.
-8z - 36 = 4
Add 36 to both sides.
-8z - 36 + 36 = 4 + 36
Simplify.
-8z = 40
Divide both sides by -8.
z = -5
8. 3/2(x - 2) - 5 = 19
Simplify.
3/2x - 3 - 5 = 19
Simplify.
3/2x - 8 = 19
Add 8 to both side.
3/2x = 19 + 8
Simplify.
3/2x = 27
Multiply both sides by 2.
3/2x · 2 = 27 · 2
Simplify.
3x = 54
Divide both sides by 3.
x = 18
~hope I helped~
Answer:
x=9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(y−10)=−5
(5)(y)+(5)(−10)=−5(Distribute)
5y+−50=−5
5y−50=−5
Step 2: Add 50 to both sides.
5y−50+50=−5+50
5y=45
Step 3: Divide both sides by 5.
5y
5
=
45
