146.6. Nearest tenth is one place after the decimal.
So in equations you want to do the same thing to both sides so that the equation will stay equal
when dealing with one unknown number (m) try to get them all on the same side
0.6m+3=2m+0.2
I usually like positive unknowns so
subtract 0.6m from both sides
3=1.4m+0.2
subtract 0.2 from both sides
2.8=1.4m
divide both sides by 1.4
2.8/1.4=2=x
if dividing by decimals move the decimal either round the decimals up or down then divide. or multiply them by the 10 to the same power then divide.
x=2
Complete Question
The length of the guy wire supporting a cell tower is 120 m. The guy wire is anchored to the ground at a distance of 80 m from the base of the tower to the nearest hundredth of a meter how tall is the tower?
Answer:
89.44m
Step-by-step explanation:
We solve this question using the Pythagoras Theorem
This is given as:
Hypotenuse² = Opposite ² + Adjacent ²
Hypotenuse = Length of the guy wire = 120m
Adjacent = Distance from the base of the tower = 80m
Opposite = Height of the building = x
Hence:
120² = x² + 80²
Collect like terms
x² = 120² - 80²
x = √120² - 80²
x = √(8000)
x = 89.4427191 m
Approximately the height of the tower is = 89.44m

Step-by-step explanation:
If we're talking in whole numbers, the only multiplication of whole numbers that equals two is
2 * 1
or
-2 * -1
