A cube has a volume of 2197 m^3. Its surface is to be painted. Each can of paint covers about 40 m^2. How many cans of paint are

Gelneren [198K]

Volume= a³
a=edge
2197 = a³
=> a=13 m
Surface area=6a²=6*13²=6*169=1014 m²
 $\frac{1014}{40}$ = 25,35 ≈ 26

Find the value of x in the equation 3(2x-4)-5(x-2)=1

Lyrx [107]

Answer:

x=3

Step-by-step explanation:

3(2x−4)−5(x−2)=1

Step 1: Simplify both sides of the equation.

3(2x−4)−5(x−2)=1

(3)(2x)+(3)(−4)+(−5)(x)+(−5)(−2)=1(Distribute)

6x+−12+−5x+10=1

(6x+−5x)+(−12+10)=1(Combine Like Terms)

x+−2=1

x−2=1

Step 2: Add 2 to both sides.

x−2+2=1+2

x=3
