Answer: 3

Step-by-step explanation:

25 x (5 - 2) ➗ 5 - 12

Applying the rule of BODMAS

- Solve task in bracket first

25 x (5 - 2) ➗ 5 - 12

= 25 x (3) ➗ 5 - 12

= 75 ➗ 5 - 12

- Solve task of division next

75 ➗ 5 - 12

= 15 - 12

= 3

Thus, the answer is 3

What is the surface area?????
Elenna [48]

The area of a triangle is found using the formula Area = 1/2 x base x height.


Base = 8

Height = 18.


The area of 1 triangle = 1/2 x 8 x 18 = 72 square units.


There are a total of 4 sides, so total area = 72 x 4 = 288 units ^2

Solve each system by elimination. Check the solution in both of the original equations.
elena55 [62]

Answer:

After finding the solution of given equations by elimination method

-3x-3y=12

-9x+3y=-24

we get the value of x=1 and y= -5

Step-by-step explanation:

-3x-3y=12 is eq A

-9x+3y= -24 is eq B

To find out value of x and y we will use elimination method

To find value of x add eq A and eq B

(-3x-3y)+ (-9x+3y)= 12 + (-24)\\-3x-3y-9x+3y= 12-24\\-12x = -12\\dividing \,\,by -12\,\,on\,\, both\,\,sides\\\frac{-12x}{-12} = \frac{-12}{-12} \\x= 1

Now to find value of y put x=1 in eq A

(-3 \times 1 )- 3 y=12\\-3 -3y =12\\\\adding\,\,3\,\,on\,\, both\,\,sides\\-3y=12+3\\\\dividing\,\,-3\,\,on\,\,both\,\,sides\\y= \frac{15}{-3} \\y= -5

so the value of

x= 1

and

y= -5

For checking the solution

putting value of x and y in eq A

-3x-3y=12\\-3(1)-3 (-5)=12\\-3+15=12\\12=12\\

Hence proved

Putiing value of x and y in eq B

-9x+3y=  -24\\-9(1) + 3 (-5) = -24\\-9 -15 = -24\\-24= -24\\

Hence proved

Two blueberry farms are similar in shape. The ratio of the side lengths of the farms is 4:5, and the smaller farm has a perimete
tatuchka [14]

Answer:

$337.5

Step-by-step explanation:

4:5=360:x        360/4=90     90+360=450 check 360/450=0.8 and 4/5=0.8

4:5=360:450

larger farm perimeter is 450 yards so dig a trench 0.75 per yard

so 450 * 0.75 = $337.5

Hope this helps! :)
