Answer:
tall candles = 39
Short candles = 52
Step-by-step explanation:
let tall candles be x
and short candles be y
No. Of candles sold = x + y =91
Money made from candles will be equal to = 8x + 5y = $572
These both are simultaneous linear equations.
x + y =91 ( multiply by 5)
5x + 5y = 455
8x + 5y = $572
Subtract them:
-3x = -117
x = -117/3
x = 39
put value of x in
x + y = 91
39 + y = 91
y = 91 - 39
y = 52
x shows tall candles so they are 39
y shows short candles so they are 52
The formula to find the Height of a triangle when you have the Area and the base is H = 2 * A/b
if the Area is 36.8 then divide it by 4.6. You get 8. put 36.8 in calculator first, then 4.6 = 8
2 x 8 = 16...so the answer should be 16 inches.
2 is in the formula to multiply to the number you get after dividing the base into the Area.

Kim because just cause man. 14/12 can be turned into 7/6... boom knowledge??
Answer:
Step-by-step explanation:
The equation of a proportional relationship: y = mx.
METHOD 1:
We know: If x and y are in a proportional relationshi, then the ratio y/x is constant
We have P(3, 2) and Q(x, 6). Therefore
<em>cross multiply</em>
<em>divide both sides by 2</em>
METHOD 2:
<em>(look at the picture)</em>
The graph of y = mx is a straight line passes through the origin.
Step 1.
Plot point P(3, 2) on the graph.
Step 2.
Draw the line passes through he origin and point P.
Step 3.
Draw the line y = 6 <em>(6 from the coordinates of Q(x, 6))</em>
Step 4.
The intersection of lines is the point Q. Read the coordinte x.
