A store sells bread and milk. On Tuesday, 3 loaves of bread and 2 litres of milk were sold for €6.25. On Thursday
poizon [28]

Answer:

A store sells bread and milk. On Tuesday, 3 loaves of bread and 2 litres of milk were sold for €6.25. On Thursday  4 loaves of bread and 5 litres of milk were sold for €10.90. If b = the price of a loaf of bread and m = the price of

one litre of milk, Tuesday's sales can be written as 3b+2m=6.25.

Part A Using simplest terms, write an equation in band m for Thursday's sales.  

PartB calculate the values of b and m

3b + 2m= 6.25  >> Tuesday equation 1

4b +  5m = 10.90 >> Thursday equation 2

Subtract equation 1 and 2

3b+2m-6.25-4b+5m-10.90= 0

b+7m-4.65= 0

b+7m= 4.65+0

b+7m= 4.65

b= 4.65 - 7m

if b= 4.65-7m

then substitute b in b+7m=4.65

4.65-7m+7m= 4.65

4.65-m= 4.65

4.65-4.65= m

m= 0

A student's grade for the four quarters are 95, 83, 91, and 85. What does the student need to earn on the final exam to have an
gulaghasi [49]

Answer:

The least score the student can get is 71 to get an overall B average at the end of the year.

Step-by-step explanation:

Let the score she needs to get be = x

We now have to take the mean of all the five subjects <em>(including x)</em> and equate it to the least score she can have to get a B grade.

Let us take the least score the student needs to get a B grade to be 85

Mean of all 5 scores =

\frac{95+83+91+85+x}{5}=85

\frac{354+x}{5} =85

354+x = 425

x = 71

The least score the student can get is 71 to get an overall B average at the end of the year.
