99÷128=0.7734375 multiply by 100 the round to whole number and get 77%
77% is answer
$1.21 is the original price per pound...i too am having trouble with figuring out how to setup the equation!!
Hey :))
(-p,-q)(p,q)slope = (q - (-q) / (p - (-p) = (q + q) / (p + p) = 2q / 2p = q/p
y = mx + b.....slope(m) = q/p(p,q)...x = p and y = qnow we sub and find b, the y intq = (q/p)(p) + bq = q + bq - q = b0 = b
so ur equation is : y = (q/p)x + 0...or just y = (q/p)x....its answer B
HOPE THIS HELPED!!! :))
It is true that bad road condition does have a direct impact
on the physical, emotional and economic aspects to the family, the community
and the country. Bad roads can cause accidents which directly impacts a person
physically. Mentally it is very stressful for a person to drive on bad roads. He
or she has to be extra careful regarding potholes and other damages that have
happened to the road. Economically bad roads can be the reason for price rise
of products as time required to move a product via road is more. Also the cost
of transport increases drastically.
Answer : 96
x – y = 16
--------> equation 1
x is the higher grade and y is the lower grade
We solve the first equation for y
x - y = 16
-y = 16 -x ( divide each term by -1)
y = -16 + x
Now substitute y in second equation
Take common denominator to combine fractions
Add 8 on both sides
Multiply both sides by 
x = 96
We know x is the higher grade
96 is the higher grade of Jose’s two tests.
