Ryan is making small meat loaves. Each small meat loaf uses 3/4 pound of meat. How much meat does Ryan need to make 8 small meat
taurus [48]
Ryan will need 6 pounds of meatloaf. If you want to know how I got my answer, my work along with the answer will be shown below:

3/4 pound=1 small meatloaf

*Multiply 3/4 pound by 8 because he wants to make 8 small meat loaves, or just add 3/4+3/4+3/4+3/4+3/4+3/4+3/4+3/4*.

#1 way (recommended): 3/4*8/1=24/4....=6 pounds
#2 way: 3/4+3/4=6/4+3/4=9/4+3/4=12/4+3/4=15/4+3/4=18/4+3/4=21/4+3/4=24/4=6 pounds

I hope this helps! Let me know if you still need help!

Solve the system by elimination. (Please explain how to do it)
Naddika [18.5K]

Apply to Row 2 : Row 2 + Row 1

2x + 2y + 3z = 0

y + 4z = -3

2x + 3y + 3z = 5

Apply to Row 3: Row 3 - Row 1

2x + 2y + 3z = 0

y + 4z = -3

y = 5

Apply to Row 3: Row 3 - Row 2

2x + 2y + 3z = 0

y + 4z = -3

-4z = 8

Simplify rows

2x + 2y + 3z = 0

y + 4z = -3

z = -2

<em>Note that the matrix is in echelon form now. The next steps are for back substitution.</em>

Apply to Row 2: Row 2 - 4 Row 3

2x + 2y + 3z = 0

y = 5

z = -2

Apply to Row 1: Row 1 - 3 Row 3

2x + 2y = 6

y = 5

z = -2

Apply to Row 1: Row 1 - 2 Row 2

2x = -4

y = 5

z = 2

Simplify the rows

<u>x = -2</u>

<u>y = 5</u>

<u>z = -2</u>

sveta [45]
Hello,

x^2+y^2+8x-6y+21=0

Rewritten in the form of a standard circle equation:

(x-(-4))^2+(y-3)^2=2^2

Therefore, the circle properties are:

(a,b)=(-4,3),r=2

The radius of the circle whose equation is <span>x^2 + y^2 + 8x - 6y + 21 =0 is 2.

Of all the species in the world, 4 out of every 5 are insects. What percentage of species are insects?
kow [346]

Answer:

80%

Step-by-step explanation:

Bugs are 4/5, but you can't do that as a precentage. You then multiply 5 x 2 to get 10, and 4 x 2 to get 8. Then, you multiply both by 10, and then you take out the fraction and replace it with a precent sign. Then you get your answer, 80%.
