Answer:

5 2/3

Step-by-step explanation:

So because it is a mixed number that means you want to have a whole plus a fraction. You keep the 5 as the whole and because 2/3=.666666. You add them together making 5 2/3.

Answer:

y= [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

change them to improper fractions

2 1/2= 5/2    1 2/3=5/3

divide y from 5/3:

[tex]\frac{5}{2} y=\frac{5}{3}[/tex]

mutiply each side by 2/5

y=10/15=2/3

here is your answer. change them to improper fractions

2 1/2= 5/2    1 2/3=5/3

divide y from 5/3:

mutiply each side by 2/5

y=10/15=2/3

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 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.

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer: Choice B) 0.63

==============================================

Work Shown:

1.1 is 174% of what number

1.1 = 174% of what number

1.1 = 174% of x

1.1 = 1.74*x

1.74x = 1.1

x = 1.1/1.74

x = 0.632183908045977 which is approximate

x = 0.63

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.
