20 large candles because $4*20 candles=$80
2 small candles because $2.50*2=$5
$80+$5=$85
Answer:
PQ = 
Step-by-step explanation:
given MQR = 60, PQR = 75
MQP = 75 -60= 15
WE KNOW THAT MQR +QRM +QMR = 180
MPQ = MQP AS ANGLE OPPOSITE TO EQUAL SIDES ARE EQUAL
THEREFORE QMR = 90 - 60 = 30
therefore PQM = 75 - 60 = 15
PM = PQ because M is the mid point
therefore PR = PM + 
PR = 

PQ = 
Answer:
x = 2
Step-by-step explanation:
note that 4096 =
, then
= 
Since bases on both sides are equal, both 8 , then equate the exponents
2x = 4 ( divide both sides by 2 )
x = 2
The correct numbers are 55 and 47, because they have a difference of 8 and a sum of 102.
Answer:
amusing you mean 3x^2-8x-16 the answer is when x is equal to -4/3 and 4
Step-by-step explanation:
3x^2-8x-16 ------> (3x+4)(x-4)
3x+4=0 ----> 3x=-4 ----> x=-4/3
x-4=0 ----> x=4
