8is the answer. Plug in 8 for x and solve
If c represents that cost, then
.. 12/80 = c/120
.. c = 120*(12/80) = 18
The cost of the larger candle is $18.
Answer:
B
Step-by-step explanation:
Since T is at the midpoint of SU, then
ST = TU , substitute values
8x = 3x + 20 ( subtract 3x from both sides )
5x = 20 ( divide both sides by 5 )
x = 4
Thus
ST = 8x = 8(4) = 32
Answer:
The slope is zero. Since both coordinates have the y-value of -1, they are on the same line on the graph and form a horizontal line with a slope of zero. (a straight horizontal line)
Step-by-step explanation:
use the formula
(y2-y1)/(x2-x1)
to calculate the slope using 2 points
so where (x1,y1) (x2,y2) can be subsituted
so putting it in the formula ...
(-1-(-1))/(7-10)=
0/-3=0
Y intercept is -4
slope is 2/5 i think
