Covert each into algebraic equations 1.Twice a number is eight less than four times that number.

2.Four times the sum of a number and two is twenty.

3.Nine less than twice a number is four times the sum of the number and five.

1) 2x=4x-8

2) 4(x+2)=20

3) 2x-9=4(x+5)

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
