work out 1/5 of 80 =

Answer:

I think that the first part would be -252, but I'm not sure about the second part

Step-by-step explanation:

Answer:

Some examples of linear equations in two variables are: 1.2s + 3t = 5, p + 4q = 7, πu + 5v = 9 and 3 = 2 x – 7y. Note that you can put these equations in the form 1.2s + 3t – 5 = 0, p + 4q – 7 = 0, πu + 5v – 9 = 0 and 2 x – 7y – 3 = 0, respectively.

Answer:

x=106

Step-by-step explanation:

Answer:

100

Step-by-step explanation:

1 yard = 3 feet

6 yards = 18 feet

(18*2)+(32*2)

36+64

100

Answer:  The perimeter is a 100 feet.

Step-by-step explanation:

If it is 32 feet long and 6 yards wide then I am thinking that the shape will be a rectangle.

To find the shape of a rectangle, you can use the formula,  P = 2l+2w  were P is the perimeter, l is the length, and w is the width.  

But first since feet and yards are different measurements, and the question is asking for the perimeter in feet, then you will first have to convert 6 yards to feet.  

6 yards = 18 feet  

This means that the sides  will be 32 feet long and 18 feet wide.

Now using the formula, input 32 for L and 18 for W and solve for P the perimeter.

 P  = 2(32) + 2(18)

P = 64+ 36

P = 100  

Answer:

d. 18

Step-by-step explanation:

Lengths AG and CF of the parallelogram are equal.

i.e AG = CF

where AG = 2x + 10

          CF = 5x -2

→ 2x + 10 = 5x-2

(collecting like terms): 5x - 2x = 10 + 2

→ 3x = 12

x=12÷3 = 4

∴ CF = 5x -2 = 5(4) -2 = 20 - 2 = 18

∴ CF = 18 (answer)

Answer:

13.7 years

Step-by-step explanation:

The equation of the line of the best fit is N = 62t + 35

where

N is the number of enrollments

t is years after the  year 2006

If the actual enrollment is 885 students. Put N = 885 in the given equation.

885 = 62t + 35

or

885 -35 = 62t

850 = 62t

t = 13.7 years

So, the required answer is 13.7 years.

Answer:

n= -9, t= -9

Step-by-step explanation:

1) -1/3(n+15)=-2

-1/3×n+-1/3×15=-2

-1/3×n -5= -2

-1/3 n-5+5= -2+5

-1/3×n=3

3/-1×-1/3×n=3/-1×3

n= -9

2) 46 = -6t -8

−6t−8=46

−6t−8+8=46+8

−6t=54

Divide both sides by -6

t=-9

Answer:

A.) 3/4

Step-by-step explanation:

You can find this by dividing the distance from point Z to point Y by the distance of point X to point Y. The distance from Z to Y is 6 and the distance from X to Y is 8, so that means that the slope is 6/8, which simplifies to 3/4.

Answer:

[tex]\mathbf{ \dfrac{1}{8} \ box}[/tex]

Step-by-step explanation:

Given that:

Steve divided 5/8 of a box evenly among 5 bottles. To determine the amount of baking soda added;

Then, mathematically:

[tex]=\dfrac{5}{8} \ box \div 5[/tex]

[tex]= \dfrac{5}{8} \ box \times \dfrac{1}{5}[/tex]

[tex]\mathbf{= \dfrac{1}{8} \ box}[/tex]

Answer:

The college spread is best described by the IQR. The high school spread is best described by the standard deviation.

Step-by-step explanation:

The college data has large outliers which skews the data, therefore the IQR is better measure of spread.

The high school data does not appear to be skewed so the standard deviation is fine as a measure of spread.

Answer: 11 because the distance between A-B is 8 so because it says it on top, then add 3 to it from B to C

Answer:

The numbers are  x= 9 and y =6

The product of two numbers

x y  = 9 × 6 = 54

Step-by-step explanation:

Step(i):-

Let x and y are two numbers

Given that the sum of two numbers

 x + y = 15 ..(i)

Given that the difference of two numbers

x - y = 3 ..(ii)

adding (i) and (ii) , we get

x + y + x -y = 15 +3

  2 x = 18

    x =9

Step(ii):-

Substitute x = 9 in equation (i) , we get

x + y = 15

9 + y = 15

     y = 15 - 9

    y = 6

Final answer:-

The numbers are  x= 9 and y =6

The product of two numbers

x y  = 9 × 6 = 54

Answer:

60

Step-by-step explanation:

So we have all four side lengths: 8, 3, 10, and 9. Since there's one diagonal side, the best way to solve this is to split the shape in two. So the area of the first shape would be 24 because 8 x 3 is 24. The other one would be different. The side length is 8, so we multiply 9 by 8 and get 72. But since it's a triangle, we have to divide that by 2. Then we get 36. If you add 36 and 24, you get 60. That would be your area.

difference in acres

Answer:

2 in

Step-by-step explanation:

Given data

Area= 7 in^2

Volume= 14 in^3

from

Volume= Area* height

substitute

14= 7*x

divide both sides by 7

x=14/7

x= 2 in

Hence the height is 2 in

Answer:

( 5 + s ) 4 = 20 + 4 s

Step-by-step explanation:

Distribution property

Let a, b and c are numbers then distribution property is defined by

a( b + c) = a b + a c

(a+ b) c = a c + b c

Given that

( 5 + s ) 4 = 5× 4 + s× 4

               = 20 + 4 s

Final answer:-

( 5 + s ) 4 = 20 + 4 s
