Answer:

6t = -21

Step-by-step explanation:

To find the 6t, we would first have to find t. To find t, we can solve for t in the equation 3t - 7 = 5t.

3t - 7 = 5t

Subtract 3t from both sides to get rid of the 3t on the left side.

-7 = 5t - 3t

Simplify.

-7 = 2t

Divide both sides by 2 to get rid of the coefficient of 2 on the right side.

-7/2 = t

t = -7/2

Now we found that t = -7/2. To find 6t, plug in -7/2 for t.

6(-7/2) = -21

So 6t = -21.

I hope this helps. :)

Answer:

6t = -21

Step-by-step explanation:

3t-7 = 5t simplifies by subtracting 5t on both sides, then adding 7 on both sides:

3t -5t -7 +7 = 5t-5t+7

-2t = 7

t = -7/2

Then 6t = 6*-7/2 = -21

A composite solid consists of a cube with edges of length 6cm and a square pyramid with base edges of length 6cm and height of 6

icang [17]

Answer: The volume of the solid is 324 cm³

Step-by-step explanation:

Formula for determining the volume if a cube is s³

Where s represents the length of each side of the cube.

From the information given, s = 6 cm

Volume = 6³ = 216 cm³

The formula for determining the volume of the square base pyramid is expressed as

Volume = Area × height × 1/3

From the information given,

Length of square base = 6 cm

Height = 6 cm

Area of square base = 6² = 36 cm²

Volume of square base pyramid

= 36 × 6 × 1/3 = 108 cm³

The volume of the solid would be the sum of the volume of the cube and the volume of the square base pyramid. It becomes

216 + 108 = 324 cm³

***PLZ HELP! WILL GIVE BRAINLIEST!!*** The face of a clock is a circle. The ratio of the area, in square centimeters, of the f

devlian [24]

The area of a circle is given in terms of circumference by
.. A = C²/(4π)
Then the ratio A/C is
.. A/C = C/(4π)
Substituting the given information, we have
.. 16 cm = C/(4π)
.. C = (4π)*16 cm = 64π cm
.. C ≈ 200.96 cm

When the fifth term of an arithmetic sequence whose common difference is D=six and whose first term is a1 =four

kodGreya [7K]

Answer:

28 is the answer

Step-by-step explanation:

in an arithmetic sequence nth term An is given by the equation

$an \: = a1 + (n - 1) \times d$

where A1 is first term and d is common difference. thus from the question we have

$a5 = 4 + ((5 - 1) \times 6) \\ = 4 + (4 \times 6) \\ = 4 + 24 \\ = 28$
