Answer:
For the mathematical system that consists of the set of real numbers together with the operations of addition, subtraction, multiplication, and division, the resulting properties are called the properties of real numbers.
Closure Property of Addition also holds in real numbers: The sum of two real numbers is a real number.
multiplication pairs any two real numbers with a real number to become a product a×b
for all real numbers a and b, the difference denoted as a - b is defined by: a - b = a + (-b).
Hence we can also apply the BODMAS rule to the real numbers.
Answer:
each hamburger costs $3.50
Step-by-step explanation:
he spent $13 in total and bought one hot dog for $2.50 and 3 hamburgers but we don't know the price of one hamburger so we could represent it by the equaton,
2.50 + 3h = 13 now solve for x
-2.50 2.50
3h = 10.50
h=3.50
check:
2.50+3(3.50)=13
2.50+10.50=13
13=13
Answer:
15×5= 75 pencils
75/26= 2 pencils each student
23 pencils leftover
Not sure but think A=1, X=2, Y=3.If this is for a grade try to work it out some but these numbers work when they sre plugged in where they sre sippose to be.
It’s c. Easiest and self explanatory.
