270/15 = 135/ 7.5
cross multiply to see if it is a true proportion
(15)(135) = (270)(7.5)
2025 = 2025 (correct...so this is a true proportion)
answer is : bottom right one
Answer:
- 10
Step-by-step explanation:
Step 1:
5 ( x - 4 ) = 7x Equation
Step 2:
5x - 20 = 7x Multiply
Step 3:
- 20 = 2x Subtract
Step 4:
x = - 20 ÷ 2 Divide
Answer:
x = - 10

The relative order of the metric prefixes is micro-, milli-, centi- and kilo-,
<h3>What are metric units?</h3>
Metric units are units used to measure quantities
The units are given as:
kilo-, micro-, centi-, and milli-
In metric units, the value of each prefix is:
Kilo = 1000
Micro = 0.0001
Centi = 100
Milli = 0.1
In order of arrangement, we have:
Micro = 0.0001
Milli = 0.1
Centi = 100
Kilo = 1000
Hence, the relative order of the metric prefixes is micro-, milli-, centi- and kilo-,
