How can properties of operations be used to subtract expressions

Mathematics

Properties of operations can be used to subtract expressions  because <span>If you don't, you'll get the wrong answer, because you'll perform the solution steps in the wrong order. Also The Order of Operations provides us with a fixed approach to solving algebraic expressions. Without them, it would be impossible to get the same results because everyone would solve algebraic expressions in their own unique way. With the Order of Operations, everyone who solves a given problem will arrive at the same solution(s). This is what makes it possible to tackle problems like predicting the orbit path of Mars so we can land a probe on it...or develop software that does your math homework for you.;) </span>

Three litres of milk cost r29,95 at shop a and two liters of milk cost r15,95 at shop
Savatey [412]
At first shop the 3 liters of milk cost 2995
cost per liter = cost / volume
cost per liter = 2995 / 3 L
cost per liter = 998 per liter of milk

at second shop the two liters of milk cost 1595
 cost per liter = cost / volume
cost per liter = 1595 / 2 L
cost per liter = 797.5 per liter of milk

Grades 3, 4, and 5 have their annual field day together. Each grade level is given 16 gallons of water.
sineoko [7]

Answer:

Their will be enough water for each student to consume 2 cups of water.

Step-by-step explanation:

Grade 3, 4 and 5 have their annual field day together . Each grade level is given 16 gallons of water. This means the three grades have 16 × 3 = 48 gallons of water.

The total students involved is 350 student. The total student is the sum of the student in all three grades.

Since the water will be distributed to the students in cups let us convert gallons to cups.

1 gallons = 16 cups

48 gallons = ? cups

cross multiply

48 × 16 = 768 cups.

768 cups of water is available to be shared among the 350 students.

1 student is entitled to 2 cups of water.

350 students will consume 350 × 2 = 700 cups of water.

Therefore, their will be enough water for each student to consume 2 cups of water.

Which graph shows the solution to the system of linear inequalities?
ICE Princess25 [194]

Answer:

x = 6 ; Rewritten: 2x-3y-12=0 ; y=-4

Step-by-step explanation:

2x-3 multiply 0=12

x=6 ( that's the function)

Rewritten steps: 2x-3y=12 then move constant to the left by adding its opposite to both sides which gives you 2x-3y-12=12-12. After the sum of two opposites equals 0 which is 2x-3y-12=0

Y Intercept :

2x-3y=12 and to find y intercept, sub x = 0 ; to 2 multiply 0 -3y=12 and then you solve for the equation which is your answer.
