Answer: 800
Step-by-step explanation:
Answer:
The expressions in order from least (1) to greatest (5) based on their values is:
6a − 2b
2a + b
2b + a
4b − a
3(a + b)
Step-by-step explanation:
a = 3 and b = 5
2a + b
2b + a
3(a + b)
4b − a
6a − 2b
Replacing the value of a and b inside the expression we have:
2a + b = 2(3) + 5 = 6 + 5 = 11
2b + a = 2(5) + 3 = 10 + 3 = 13
3(a + b) = 3(3 + 5) = 3(8) = 24
4b − a = 4(5) - 3 = 20 - 3 = 17
6a − 2b = 6(3) - 2(5) = 18 - 10 = 8
The expressions in order from least (1) to greatest (5) based on their values is 8, 11, 13, 17 and 24.
The solution is x = 6
Step-by-step explanation:
Let us revise some rules of the exponents
- If , then n = m
∵
∵ 9 = 3 × 3
∴ 9 = 3²
- Substitute 9 by 3² in the equation above
∴
- Use the second rule above for the left hand side
∵
∴
∴
- By using the first rule above
∴ 2x + 30 = 7x
- Subtract 2x from both sides
∴ 30 = 5x
- Divide both sides by 5
∴ 6 = x
The solution is x = 6

Thee linear equation which contains the points (-2,5) and (4,1) is
Graph The points which is in the equation (-2,5) and (4,1).
Equation is basically a relationship between two or more variables and it is usually in equal to form. It is equated to find the value of variables. We can also make graphs of different equations. Linear equation is a equation whose graph looks like straight line means values comes from a relationship. It not necessarily means parallel to any axis.
The linear equation can be found by:
where the coordinates are
Hence the equation which has points (-2,5)(4,1) is
