You first want to subtact 4n with n which would give you 3n. Then u would do
3n=2+ -4 Then you would add 4 and 2 which would give you 6. then u divide by 3 which would give u 2. N=2

write an equation to represent the relationship, and find the amount of peanut butter used to make 25 cracker packages. the tabl

Nadusha1986 [10]

We are given 4 points.

$(\frac{1}{2},2)$

$(\frac{5}{8},\frac{5}{2})$

$(\frac{3}{4},3)$

$(\frac{7}{8},\frac{7}{2})$

Using this, we can make an equation.

$y=4x$

I got $m=4$ by using the slope formula.

$m=\frac{2.5-2}{0.625-0.5}$

$m=\frac{0.5}{0.125}$

$m=4$

So the equation we have is $y=4x$

Now, we can solve for how much peanut butter is used to make 25 packages by plugging in 25 for $y$ , which is the number of cracker packages.

$25=4x$

$x=\frac{25}{4}$

We need to use $\frac{25}{4}$ teaspoons of peanut butter to make 25 packages of crackers.

Hope this helps.

頑張って!

Find the exact values of the following,giving your answers as fractions

Vsevolod [243]

Answer:

(a) $3^{-2}=\frac{1}{9}$

(b) $4^{-3}=\frac{1}{64}$

(c) $2^{-6}=\frac{1}{64}$

Step-by-step explanation:

To find the exact value in fractions of the followings:

Exponents also called powers its a way of expressing a number multiplied by itself by a certain number of times.

Using $a^{-m}= \frac{1}{a^m}$ .......[1]

(a)

Fraction represents a part of a whole or more generally, any number of equal parts.

$3^{-2}$ = $\frac{1}{3^2}=\frac{1}{3\times 3}=\frac{1}{9}$ [ Using [1]]

(b)

$4^{-3}$ = $\frac{1}{4^3} =\frac{1}{4\times 4\times 4}=\frac{1}{64}$ [ Using [1]]

(c)

$2^{-6}$ = $\frac{1}{2^6} =\frac{1}{2\times 2\times 2\times 2\times 2\times 2}=\frac{1}{64}$ [ Using [1]]
