Answer:

$7m+2$

Step-by-step explanation:

Commutative property of addition: $x+y=y+x$

$-6+7m+8\\=7m-6+8\ \ \ \ \ (using\ commutative\ property\ of\ addition)\\=7m+(-6+8)\ \ \ \ (using\ associative\ property\ (x+y)+z=x+(y+z))\\=7m+2$

12, 13, 15, 20, 24, 25, 26, 31, 33, 34

First, let's just find everything (minimum, maximum, Q₁, median {Q₂}, Q₃)

Minimum : 12, because it is the lowest number.

Maximum : 34, because it is the highest number.

Median (Q₂) : 24.5, because it is the middle number.

Q₁ : 15, because it is between 24.5 and 34

Q₃ : 31

So,

1) d-12

2) c - 34

3) b-15

4) f-24.5

5) a-31

PLEASE HELLLLLLLPPPPPP!!!!!

MariettaO [177]

Answer:

Step-by-step explanation:

First, let's define the types of numbers.

Real numbers: a value that represents a quantity along a continuous line

ex: 1, 5, -6, 0.125, 45.5258,

Integer: Zero, any positive or negative number

ex: -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5....

Whole numbers: a number without fractions [not negative]

ex: 0, 1, 2, 3, 4, 5.....

Rational numbers: any number that can be expressed as the quotient or fraction

ex: 1, 2, 3, 4, 5

Irrational numbers: any number that can't be expressed at the quotient or fraction

ex: pi, [3.14.... (never ending decimal)] square root of 2....

Based on this information, the false statment would be A. I believe, because

pi is a real number and it is an irrational number.

I hope this helps!!! :)

the area of a rectangle garden is 38 1/4 square meters.The width of the garden is 4 1/2 meters.Find the length of the garden.

never [62]

Area = 38 1/4 = 153/4

Width = 4 1/2 = 9/2

Area = Length x Width

Length = Area/Width

So divide both of them:
$\sf{ \frac{153}{4} \div \frac{9}{2} =\sf{ \frac{153}{4} \times \frac{2}{9} = \frac{9 \times 17}{2\times 2}\times \frac{2}{9} = \frac{17}{2}$

So the length is equal to $\boxed{\sf{\frac{17}{2}}}$
