Answer:
1. x = 4 and y = 1
2. x= 5 and y = 3
Use the examples below to complete 3 and 4.
Step-by-step explanation:
To solve each system of equations, use elimination.
1. Stack the equations and subtract to perform elimination.
2x + 2y = 10
- x + 2y = 6
-------------------------
x = 4
Substitute x = 4 into an equation to solve for y.
2(4) + 2y = 10
8 + 2y = 10
2y = 2
y = 1
2. Stack the equations and subtract to perform elimination.
3x + y = 18
- 2x + y = 13
-------------------------
x = 5
Substitute x = 5 into an equation to solve for y.
3(5) + y = 18
15 + y = 18
y = 3
Continue the same method for numbers 3 and 4.
Answer:
101
Step-by-step explanation:
Given the expression:
2016 · 199 = 2016·? +2016 · 98
We could rewrite the expression such that the missing value equals x
2016 * 199 = 2016 * x + 2016 * 98
Using BODMAS:
401184 = 2016x + 197568
401184 - 197568 = 2016x
203616 = 2016x
Divide both sides by 2016
203616 / 2016 = 2016x / 2016
101 = x
Hence, missing value is 101
Answer:
36, 49, 64
Step-by-step explanation:
6 squared, 7 squared, 8 squared makes 149
Based on the definition of integers, ordering them would depend on if they are negative, positive, or have a zero value.
<h3>How are integers ordered?</h3><h3 />
Integers are whole numbers such as 1, 15, and 55. There are no decimals and they do not come in the form of fractions.
Integers can be negative or positive. Positive integers are always higher than negative integers. For instance, 1 is more than -500,000.
If both integers are negative, the larger looking number is considered smaller. For instance, -5 is more than -55. For positive integers, this is the reverse with larger looking numbers being larger.
An example of the correct order of intergers based on this dataset (1, 52, -800, 86, 5, and -4) is:
= -800, -4, 1, 5, 52, 86
