Write a system of equation based on the number
For an instance, the two numbers are a and b.
"The sum of two numbers is 59" can be written as follows.
⇒ a + b = 59 <em>(first equation)
</em>"The difference is 15" can be written as follows.
⇒ a - b = 15 <em>(second equation)</em>
Solve the system of equation by elimination/substitution method.
First, eliminate b to find the value of a.
a + b = 59
a - b = 15
--------------- + (add)
2a = 74
a = 74/2
a = 37
Second, substitute 37 as a in one of the equations
a + b = 59
37 + b = 59
b = 59 - 37
b = 22
The numbers are 37 and 22
Answer:
The length of a line segment that connects vertex A and vertex b is 5 units.
( I was going to tel you how to do it but it’s long and I don’t want you to read something that’s long)
So you would first find the amount of candy that Laurie has, which is 45. When you divide it by 6, you should get 7 with a remainder of 3. So the solution is 3 pieces of candy left over.
Answer:
D. Terms that have identical variable parts
Step-by-step explanation:
Like terms refers to terms that have identical variable parts.
For example:
Given the expression
2xy + z + x + 3y - 5z + 4y - xy + 3x
The like terms in the expression are:
2xy - xy= xy
z - 5z= -4z
x + 3x= 4x
3y + 4y=7y
The new expression will be
xy - 4z + 4x + 7y
Answer: 1093 yards
Step-by-step explanation:
There are 1000 meters in a kilometer. Thus, there are 1.093*1000, or 1093 yards in a kilometer.
