Answer:

x = 12

Step-by-step explanation:

3x - 1 + x + 7 = 54

4x + 6 = 54

4x + 6 - 6 = 54 - 6

4x = 48

\frac{4x}{4}  =  \frac{48}{4}

x = 12

3(12) - 1 + (12) + 7 = 54

36 - 1 + 12 + 7 = 54

35 + 12 + 7 = 54

35 + 19 = 54

54 = 54

The top of the cylindrical can shown below has a diameter of 7 centimeters (cm).
Sidana [21]

Answer:

Circumference of the can is 21.98 cm.

Step-by-step explanation:

Since, top of the cylinder can shown in the figure is in the shape of a circle

Circumference of a circle is given by the formula,

Circumference 'C' = π × Diameter

Where r = radius of the circle

Therefore, circumference of a circle with diameter 7 centimeters will be,

C = 7π

   = 7 × 3.14

   = 21.98 cm

Therefore, circumference of the can is 21.98 cm.

at least, what i think you're asking.

400 × 0.25 = 100.

this one is extra easy because you should know that 25% is a quarter, and 400 can just be divided by 4 to get your answer.
