Answer:
a.The associative property allows us to change the grouping of terms that are added together.
b.When changing the grouping, the order of the terms stays the same; only the parentheses change position.
c.The expression a + (b + c) + d is an equivalent expression.
e.The expression (a+ b) + c + d is an equivalent expression.
Step-by-step explanation:
The correct statements are statement first, statement second, statement third, and statement fifth are correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
As we know,
The associative property allows us to change the grouping of terms that are added together.
= a + (b + c)
= (a + b) + c
The correct statements are:
The associative property allows us to change the grouping of terms that are added together.When changing the grouping, the order of the terms stays the same; only the parentheses change position.The expression a + (b + c) + d is an equivalent expression.The expression (a+ b) + c + d is an equivalent expression.Thus, the correct statements are statements first, second, third, and fifth are correct.

one third of one seventh of a land is sold for RS. 30000.What is the value of land?
Answer:
Step-by-step explanation:
Let the value of the land = Rs . 30000
[tex]\frac{1}{3}of\frac{1}{7}of x = 30000\\\\\\\frac{1}{3}*\frac{1}{7}*x = 30000\\\\\\x = 30000*\frac{3}{1}*\frac{7}{1}\\\\\\[/tex]
x = Rs. 630000
A car of mass 100 kg is moving with a velocity of 10 m/s on a road when it collides with a bus weighing 150 kg which is at rest. If both the vehicles start drifting together after the collision, find the velocity with which they are moving now?
Answer: they would be moving 15m/s
Step-by-step explanation:
10m/s times 150kg= 1500divided by 100kg=15m/s

5. What is an equation in point-stope form for the line perpendicular to y = 2x + 13 that contains (8,-4)?
y+8= - (2-4)
O y + 4 = 2(x - 8)
O x + 4 = 2(y - 8)
1
y + 4 =
Answer:
y - (-4) = (-1/2)(x - 8)
y + 4 = (-1/2)x + 4
y = (-1/2)x
orrrr...
-4 = (-1/2)(8) + b
-4 = -4 + b
b = 0
Well, we don't write "+ 0" because that's just extra work.
y = (-1/2)x
