• Sammy earned a total of $28.00.
• She picked twice as many pints of tomatoes as blueberries.
How many pints of blueberries did Sammy pick?
Answer:
Step-by-step explanation:
b = pints of blueberries
c = pints of cherry tomatoes
3b + 2c = 28
2b = c
First, substitute 2b into the c of the first equation.
3b + 2(2b) = 28
3b + 4b = 28
7b = 28
b = 4
Then, substitute 4 into the b of the second equation.
2(4) = c
c = 8
Then, substitute both values into the first equation to check.
3(4) + 2(8) = 28
12 + 16 = 28
For this case we must find the values of "a" and "b" that make the expressions equivalent:
We have:
We take common factor "2" from the numerator and denominator:
Eliminating common factors of numerator and denominator:
So, we have that the values of a and b are:

How much water does Andrew save each day with the change in shower heads if he uses the shower for 8 minutes each day?
5 gallons
16 gallons
24 gallons
40 gallons
gallons water Andrew save each day with the change in shower heads if he uses the shower for 8 minutes each day
What is equation?
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
According to questions, standard showerhead in Andrew's house dispenses 8 gallons of water per minute. Andrew changed this shower head to an energy-saving one.
The equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new shower head.
Following, this pattern, the equation for the previous shower head is
Amount of water dispensed previously
×
Amount of water dispensed after change in shower
×
Total water Andrew save each day with the change in shower
gallons
Hence, we can conclude that gallons water Andrew save each day with the change in shower heads if he uses the shower for 8 minutes each day.
