Let's start by defining our unknown number.

Let's call it x.

Now, Let's handle the first part of it. 3 more than five times a number. That can be represented by the following

$3+5x$

Now we handle the second part, "Thirty more than twice the number"

Which can be represented by

$30+2x$

So, now we set them equal, since it tells us that these expressions are the same. Then we just solve the equation

$3+5x=30+2x\\\\5x=27+2x\\\\3x=27\\\\x=9$

The answer is 9

T=months so if you have 7 months you would plug 7 in for (t)
making the equation g(7) = 2(7)

Box a has a volume of 32 cubic meters. box b is similar to box a. to create box b, box a's dimensions were tripled. what is the

Paladinen [302]

The volume of box B is (A) 864 cubic meters.

<h3>What is volume?</h3>

The amount of three-dimensional space enclosed by a closed surface is expressed as a scalar quantity.
For example, the space occupied or contained by a substance or 3D object.
Volume is frequently mathematically quantified using the SI-derived unit, the cubic meter.

To find the volume of box B:

We have been assigned a volume of 32 cubic meters.
The cubic root of 32 yields the box's dimensions, which are 3.1748 x 3.1748 x 3.1748 meters.
Meters when the dimensions are tripled: 9.5244 x 9.5244 x 9.5244

= 864 cubic meters.

Therefore, the volume of box B is (A) 864 cubic meters.

The bases of an isosceles trapezoid are represented by 4x and 2x.. The height of the trapezoid is represented by (x − 6). Which

Igoryamba

The area of a trapezoid is calculated by the equation,
A = 0.5(b₁ + b₂)h
where b₁ and b₂ are the bases and h is the height. When we substitute the given expression for the dimensions in the given,
A = 0.5(4x + 2x)(x - 6)
A = 0.5(6x)(x - 6) = 3x² - 18
Thus, the answer is letter A.

Multiple-Choice The average distance

murzikaleks [220]

Alright, so it would be helpful to think about this question in terms of units. You're given a distance (meters) and speed (meters per second). You're asked for time (which is in seconds).

If you do $\frac{meters}{meters/second}$ , your answer will be in seconds. So divide your distance (2.28 x 10^11 meters) by your speed (3.00 x 10^8 meters/second), and you should get your time!
