3. In the United States, the average amount of meat eaten
Dima020 [189]

If the average amount of meat eaten per person is 261 pounds per year then the average amount of meat eaten per day is 11 ounces.

Given that the average amount of meat eaten per person is 261 pounds per year.

We are required to find the average number of ounces of meat eaten per day.

There are 16 ounces in a pound. So,the average amount of meat eaten per person per year will be 261*16=4176 ounces per year.

Average number of ounces of meat eaten per day is there are 365 days in a year=4176/365=11.44 ounces per day.

Now by rounding it to the nearest ounce we will get 11 ounces.

Hence if the average amount of meat eaten per person is 261 pounds per year then the average amount of meat eaten per day is 11 ounces.

* Jenny marked on a coordinate plane all points with the first coordinate an integer between −12 and 7 and the second coordinate
Nat2105 [25]

Answer:

Jenny marks 414 different points on the coordinate plane.

Step-by-step explanation:

A point on a coordinate plane is represented by (x, y)

The possible values of x include all the integers between -12 and 7; that is,

-11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6.

The possible values of y include all the integers between -12 and 12; that is,

-11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11.

This means that each x-value can take on each y-value.

There are 18 x-values and 23 y-values.

Each x-value can form 23 different coordinates with all the available y-values.

18 x-values will form 18 × 23 different coordinates with the all the available y-values.

The total number of points that Jenny marks = 18 × 23 = 414.

Hope this Helps!!!

Please select the most simplified form of the equation. −12x + 26 = 1x
Damm [24]

Answer:

x=2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−12x+26=x


Step 2: Subtract x from both sides.


−12x+26 − x = x − x


−13x+26=0


Step 3: Subtract 26 from both sides.


−13x+26−26=0−26


−13x=−26


Step 4: Divide both sides by -13.


−13x/−13  =  −26/−13


x=2

I need help on question 7 and 8
DanielleElmas [232]
7.
remember
(ab)/(cd)=(a/c)(b/d)
we can split them up
and
(x^m)/(x^n)=x^(m-n)

\frac{27k^5m^8}{4k^3*9m^2}=  \frac{27k^5m^8}{36k^3m^2}=( \frac{27}{36} )( \frac{k^5}{k^3} )( \frac{m^8}{m^2} )=( \frac{3}{4})(k^{5-3})(m^{8-2} )=( \frac{3}{4})(k^2)(m^6 )= \frac{3k^2m^6}{4}



9.

2 to 3
4(x-1)=15
to
4x-1=15
the distribuutive prperty
a(b-c)=ab-ac
what he did was
a(b-c)=ab-c

he did not distribute the 4 to the -1


4(x-1)+3=18
minus 3
4(x-1)=15
distribute  4 to x and -1
4x-4=15
add 4 to both sides
4x=19
divide by 4
x=19/4
