Algebraic Expressions Practice and Problem Solving: D

Write an algebraic expression for each phrase by filling in the blanks. The first is done for you.

1. Fifty decreased by two tenths of m.

Write the expression for “Fifty decreased by”
50
Two tenths 0.2
0.2 “of m” is written as
0.2 m, or
0.2m
Put the steps together.
“Fifty decreased by” 50 “two tenths of m” 0.2m or 50 0.2m

2. Ten minus three tenths of n.
Write the expression for “Ten minus”

Three tenths 0.
Three tenths of n is written as
0. m, or
0.n.
Put the steps together:
“Ten minus than three tenths of n”

do i do it on a graph?

step-by-step explanation:

m=-16

step-by-step explanation:

answer: idk

step-by-step explanation:

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
