Two-thirds of a number minus six is 2

Vlada [557]

(2/3)n - 6 = 2

Add 6 to both sides.
(2/3)n = 8

Divide by 2/3.
n = 9 / (2/3)
n = 27/2, or 13.5

Elmer started out with$103 in his bank account .he spent $4 per week at the cafeteria for snacks.what is the slope (m) for this

pochemuha

Answer:

The equation is $y=-4x+103$

The slope is m=-4

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

y is the amount left in the saving account

x is the number of weeks

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value

In this problem we have

The slope is equal to

$m=-\$4\ per\ week$ --> is negative because is a decreasing function

The y-intercept or initial value is

$b=\$103$

substitute

$y=-4x+103$

Help me please! will mark brainliest for the correct answer

IceJOKER [234]

Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

$a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$

$(a^m)^{n}$ = $a^{mn}$

$a^{-m}$ ⇔ $\frac{1}{a^{m} }$

Thus

$4^{3x-2}$

= $4^{3x}$ × $4^{-2}$

= $(4^3)^{x}$ × $4^{-2}$

= $64^{x}$ × $\frac{1}{4^2}$

= $\frac{64^{x} }{16}$ ← as required

What is the scale factor?

Scrat [10]

Answer:

5/3 = 1.67

Step-by-step explanation:

To find how many times larger ΔMNO is, divide the side length of 15 by the original length of 9. 15 is approximately 1.67 times the size of 9, making the scale factor 1.67 or in fraction form, 5/3.
