which of these would be a helpful first step in solving the equation? check all that apply. 7x - 9 = 2x + 21
Answer: E. Subtract 2x
Step-by-step explanation:
Subtracting 2x would remove a bit from both equations, giving us 5x - 9 = 12. This would make it easier now that we only have one number on a side.
Hope this helps!

what is the volume of the figure below
Answer:
665 ft^3
Step-by-step explanation:
The formula to find the volume of pyramids is 1/3 x length x width x height. One way to solve this is by multiplying the length, width and height, and then dividing it by 3.
14 x 9.5 x 15 = 1995
1995 / 3 = 665
So the volume is 665 cubic feet

Use your answer from Question #5 and the coordinates of P to find the coordinates of P’. Explain your work, including how the scale factor was used to determine the answer.
Answer:
Scale factor is used to find the coordinates depending upon whether the scale factor value is less than one or more than one.
Step-by-step explanation:
A scale factor is a number which scales, or increases, some amount. In the condition y = Cx, C is the scale factor for x. C is likewise the coefficient of x, and might be known as the steady of proportionality of y to x.
An object is augmented if the scale factor is more noteworthy than 1. An article is decreased if the scale factor is a division, under 1. To discover the expanded picture, we initially should know the directions of our unique picture. At that point we basically increase the arrange by the scale factor to discover the widened picture.

Answer:
Step-by-step explanation: Arrange your numbers in numerical order.
Count how many numbers you have.
If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

Tommy made $72 for mowing 9 lawns. How much money would he make for mowing 15 lawns?
I don't understand this... please help :(
Answer:
Radius is the distance from the center of the circle to the edge (if you were to cut just a slice of pizza)
diameter is directly in the middle from one end to the other (if you were to cut the pizza in half)
this means that the diameter is DOUBLE the radius
circumference is the length of the outside of the circle (so the length of the pizza crust)
this one is tricky because to find circumference you need to do [tex]2\pi r[/tex] (r is the value of the radius)
so for problem 1 the radius is 3 cm (the line is equivalent to if you were trying to cut out one slice of pizza)
the diameter is DOUBLE the radius, so if you were to cut the pizza in half all the way it would be 6 cm
and the circumference ([tex]2\pi r[/tex]) is 2 * pi * 3 cm
because it says to round pi to 3.14, the circumference would be 18.84
