Write and evaluate the expression. Then, check all that apply.
eight increased by a number;
evaluate when n = 5.3
A 1-column table with 5 rows. Column 1 is labeled Addition Words with entries add, increase by, more than, sum, total.
First, write an expression.
The correct expression is n + 8.
The correct expression is 8n.
Second, substitute 5.3 for the variable, n.
Third, simplify by adding 5.3 and 8.
Third, simplify by multiplying 5.3 and 8.
The answer is 42.4.
The answer is 13.3.

The correct expression is n + 8

The value of the expression = 5.3 + 8

The answer is 13.3

Step-by-step explanation:

The expression for eight increased by a number

Assume that the number is n

Increased eight by n means add n to eight

The correct expression is n + 8

When n = 5.3

Substitute 5.3 for the variable n

The value of the expression = 5.3 + 8

Simplify by adding 5.3 and 8

5.3 + 8 = 13.3

The answer is 13.3

The answer is 1,2,4,5 and 8

Step-by-step explanation:

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
