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:

a) 4b + 5m = 10.90

b) m = 1.1, b = 1.35

Step-by-step explanation:

a) 4b + 5m = 10.90

b)

4b + 5m = 10.90

3b + 2m = 6.25

b = (10.90 - 5m)/4

b = 2.725 - 1.25m

3b + 2m = 6.25

3(2.725 - 1.25m) + 2m = 6.25

8.175 - 3.75m + 2m = 6.25

1.75m = 1.925

m = 1.1

b = (10.9 - 5.5)/4

b = 1.35

The function f(x) = 15(2)^x represents the growth of a frog population every year in a remote swamp. Elizabeth wants to manipula
weeeeeb [17]
Half one is 1/2;
half three is 3/2;
Thus, if f(x) represents annual growth, f(x)/2 shows it every half-year, like this:
\dfrac{f(x)}{2} = \dfrac{15\cdot 2^x}{2} \\  \\ 
\dfrac{f(x)}{2} = \dfrac{15}{2}\cdot 2^x

Written in plain text: f(x)=15/2*2^x

emmainna [20.7K]

Answer:

15H = D

Given that Louis makes $ 15 per hour working at the mall, to determine which equation represents the total amout of money, D, Louis makes in H hours, the following calculation must be performed:

15H = D

So, for example, if Louis worked 10 hours, the equation would operate as follows:

15 x 10 = D

150 = D
