Hi,
x + y = 350 (equation 1)
3x + 2y = 950 (equation 2)
Use Substitution Method
Isolate variable x in equation 1
x = 350 – y (equation 3)
Substitute equation 3 into equation 2
3(350 – y) + 2y = 950
1050 – 3y + 2y = 950
3y – 2y = 1050 – 950
y = 100
Substitute y = 100 into equation 1
x + 100 = 350
x = 250
Answer: 250 $3 tickets and 100 $2 tickets were sold.
Answer:
-125/27
Step-by-step explanation:
(-3/5)^-3= 1÷(-3/5)³
=1÷(-3³/5³)
=1÷(-27/125)
=1×(125/-27)
=-125/27

He uses 3/16 gal for 1/3 square foot.
1/3 square foot is 1/3 of 1 square foot.
1 square foot is 3 times as much area as 1/3 square foot, so he must use 3 times as much water. We need to multiply 3 * 3/16.
3 * 3/16 = 3/1 * 3/16 = 9/16
Answer: He uses 9/16 gallon.
if there is a total of 56 fish in the tank,than 24 of the fish are orange
The number of orange fish is 1 1/3 times the number of blue fish.
If there are 12 blue fish in the tank, then there are 18 orange fish.
Answer:
b) The number of orange fish is 1 1/3 times the number of blue fish.
Step-by-step explanation:
We are given the following information in the question:
In a fish tank, the ratio of orange fish to blue fish is 4:3.
Thus, we can write:
Thus, total number of fishes in the tank can be written as:
a) False
If there is a total of 56 fish in the tank,than 32 of the fish are orange
Total number of fish = 56
b)True
c) False
If there are 12 blue fish in the tank, then there are 16 orange fish.
Number of blue fish = 12
The question is about Temperature Measurement. The temperature shown on the thermometer is 0 degrees Fahrenheit.
Temperature measurement in mathematics involves quantifying thermal energy. The Celsius (°C) and Fahrenheit (°F) scales are commonly used. The Celsius scale sets the freezing point of water at 0°C and the boiling point at 100°C under standard conditions, while the Fahrenheit scale sets these points at 32°F and 212°F, respectively. Conversion between these scales is achieved using linear equations. In more advanced mathematics, temperature can be described using the Kelvin scale (K), where 0K represents absolute zero, the lowest possible temperature, and is used in scientific calculations involving gas laws and thermodynamics.
The picture shows part of a thermometer measuring in degrees Fahrenheit. To determine the temperature shown, we need to look at the position of the pointer on the thermometer. Based on the description provided, the pointer is more than -10 and less than 0 but closer to 0. This means the temperature is closer to 0 degrees Fahrenheit. Therefore, the temperature shown on the thermometer to the nearest integer is 0 degrees Fahrenheit.
