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

Answer:
The first one
Step-by-step explanation:
You You need to make it 5 lb of crawfish so 6$ for 4 pounds is 12$
1 pound is 3$
4 pounds + 1 pound is 15$
Shop a and b is 15$
Put them in order from lowest to highest. Identify the lowest number in the data set, as well as the highest number. Subtract the lowest number in the set from the highest number. The resulting value is the range of the set of temperature values.
Answer:
146%
Step-by-step explanation:
To find the percent increase/decrease:
1. Subtract the original value from the new value.
2. Divide by the original value.
3. Multiply the decimal by 100 to convert to a percent.
98.9 - 40.2 = 58.7
58.7/40.2 = 1.46
1.46*100 = 146%
