Step-by-step explanation:

A.

Option A is correct. The property that justifies step 4 based on the calculation is the Commutative property of addition.

Equations are expressions separated by an equal sign.

Given the equation:

2(x-3) + 3x = 19

Expand the parenthesis using the distributive law

2x - 2(3) + 3x = 19

2x - 6 + 3x = 19

Collect the like terms

2x + 3x -6 = 19

Step 4

Since 2x+3x = 3x+2x = 5x (according to the commutative law), the expression becomes:

5x-6 = 19

Step 5

Add 6 to both sides

5x-6+6 = 19+6

5x = 25

x = 25/5

x = 5

Hence the property that justifies step 4 based on the calculation is the Commutative property of addition.

i just did this in class a week ago and i think it was option c

Step-by-step explanation:

Answer:

x^2+7x=30

x^2+7x-30=0

Here a=1,b=7 and c=-30

Now,

Discriminant(D)=b^2-4ac

=7^2-4×1×(-30)

=49+120=169

By applying Quadratic formula

x=-b+- root over b^2-4ac÷2a

=-7+- root over D ÷ 2×1

=-7 +- root over 169 ÷2

=-7 +- 13 ÷2

Now,

Either x=-7+13÷2=6÷2=3

Or x=-7 -13 ÷2=-20÷2=-10

Hence, ans is (C) x=-10 and x=3

The midpoint of AB is (-5, 1).

To find the midpoint of a line segment AB, we average the x-coordinates of the two endpoints and the y-coordinates of the two endpoints.

Given that A has coordinates (-3, 8) and B has coordinates (-7, -6), we calculate the midpoint as follows:

x-coordinate of midpoint = (x-coordinate of A + x-coordinate of B) / 2

                     = (-3 + -7) / 2

                     = -10 / 2

                     = -5

y-coordinate of midpoint = (y-coordinate of A + y-coordinate of B) / 2

                     = (8 + -6) / 2

                     = 2 / 2

                     = 1

Therefore, the midpoint of AB is (-5, 1), where -5 is the x-coordinate and 1 is the y-coordinate. This means that the midpoint is equidistant from points A and B, dividing the line segment AB into two equal parts.

The value of (3.9 × 10⁻³) + 0.0026 in scientific notation is 6.5 × 10⁻³.

Decimal numbers are numbers which has basically a whole number part and a fractional or decimal part after a point called decimal point.

Decimal number system describes the base 10 number system.

Given are numbers 3.9 × 10⁻³ and 0.0026 added together.

We have to do it in scientific notation.

0.0026 can be written as 2.6 × 10⁻³.

Adding these two numbers together, and taking the common term,

(3.9 × 10⁻³) + (2.6 × 10⁻³) = (10⁻³) (3.9 + 2.6)

                                        = (10⁻³) (6.5)

                                        = 6.5 × 10⁻³

Hence the answer of the sum of (3.9 × 10⁻³) + 0.0026 is 6.5 × 10⁻³ in scientific notation.

Miles that alex can drive is 100

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

The calculation is as follows;

Number of days alex rents a car = 1 day

The charge for the car = $18 plus $0.12 per mile

Alex wants to spend; $30

The number of miles he will drive can be calculated as follows

= $30 - $18

= $12

= 12÷0.12

= 100

Therefore, if Alex spends $30 he will drive for 100 miles
