5x + 12 + 3x = 6(x + 4)

5x+3x+12=6(x+4)

Multiply the bracket by 6

(6)(x)(6)(+4)=6x+24

5x+3x+12=6x+24

8x+12=6x+24

Move 6x to the other side. Sign changes from +6x to -6x.

8x-6x+12=6x-6x+24

8x-6x+12=24

2x+12=24

Move 12 to the other side. Sign changes from +12 to -12.

2x+12-12=24-12

2x=12

Divide by 2 for both sides.

2x/2=12/2

x=6

Trevon is making payments on a computer that costs $1548. If he makes 12 equal payments, how much is three of his payments?
sammy [17]

Answer:

The answer is 387. Let's see why.

Step-by-step explanation:

The computer costs $1548. And all the 12 payments are <u>equal.</u>

To find one payment we need to divide the total cost to the number of payments.

\frac{1548}{12} = 129

Each one of the payments is $129.

To find three payment we simply follow:

129 . 3 = <u>387</u>

Another solution can be;

Since we are looking for 3 of the payments we can divide it to the total payment

\frac{3}{12} which equals to \frac{1}{4}

And we can find the answer by multiplying it with the cost which gives;

\frac{1}{4} . 1548 =387

A cone has a diameter of 8ft and height of 3ft. What’s the volume?
stepladder [879]

Step-by-step explanation:

1/3 πr²h

Given

diameter (d) = 8ft

radius (r) = d/2 = 8/2 = 4 ft

height (h) = 3 ft

Volume of cone

\frac{1}{3} \times \pi {r}^{2}  h

\frac{1}{3}  \times 3.14 \times  {4}^{2}  \times 3

\frac{150.72}{3}

=50.24 ft³
