Answer:
<em>D. 5.385 grams per cm^2</em>
Step-by-step explanation:
Density can be found using the equation:
p = m/v
(p: density, m: mass, v: volume)
Plug in the information we know.
m = 70
v = 13
So
p = 70 / 13
p = density = 5.385
9514 1404 393
Answer:
f(x) = 11x -15
Step-by-step explanation:
Often, we let x represent the input to a function. When that is multiplied by 11, the result is represented by 11x. If 15 is subtracted from that, then the expression becomes ...
11x -15
If this value is the output of function f, we write this as ...
f(x) = 11x -15
Answer:
Divide the numerator by the denominator. Your answer would be the whole number, and the remainder would be your fraction.

(ab + 174)/3 <115
multiply by 3 on each side
ab + 174 < 345
subtract 174 from each side
ab < 171
248+ ab >366
subtract 248 from each side
ab> 118
Answer 118< ab < 171
Let g and b represent the numbers of grandstand and bleacher tickets sold.
.. g + b = 5716 . . . . . . . . . total number of tickets sold
.. 65g +40b = 341690 . . value of tickets sold
Using the first equation
.. g = 5716 -b
Sustituting into the second equation
.. 65(5716 -b) +40b = 341690
.. -25b + 371540 = 341690 . . . . . collect terms
.. -25b = -29850 . . . . . . . . . . . . . . subtract 371540
.. b = 1194 . . . . . . . . . . . . . . . . . . . . divide by -25
1194 bleacher tickets were sold.
