Question.... Why no links, i wont give you any, but why does everyone dislike links? Just so u know in am 9 and i am in high school :)

Step-by-step explanation:

A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 12 feet. The width of the floor is 4 feet less than the length. It will have a stage and a closet, and the remaining area of the floor will be painted. The dimensions are shown in the diagram:

rectangle with length of x ft and width of x minus 4 ft, right triangle inside labeled stage with height of x minus 4 ft and base of 6 ft, rectangle inside labeled closet with length of 7 ft and width of 2 ft, the rest of the rectangle is labeled floor

Let A represent the painted area, in square feet, of the floor. Choose the correct equation to solve for area (A).

A = x(x − 4) + 0.5(6)(x − 4) + 2(7)
A = x(x − 4) − 0.5(6)(x − 4) − 2(7)
A = x(x − 4) − (6)(x − 4) − 2(7)
A = x(x − 4) + (6)(x − 4) + 2(7)

Answers

Answer: A=x(x-4)-0.5(6)(x-4)-2(7)

Step-by-step explanation:

A=x(x-4)-(0.5(6)(x-4) + 2(7))

A=x(x-4)-0.5(6)(x-4)-2(7)

Answer:

A = x(x − 4) − 0.5(6)(x − 4) − 2(7)

C

Step-by-step explanation:

Answer:

c)

Step-by-step explanation:

so we know that the total amount of students in said school is 180, which means that the total amount of girls in this school cannot be greater than 180

with that, let us get to solving these equations to see which one is less than 180-

a) 85/10*180=1530>180

b) 850/100*180=1530>180

c)0.85*180=153

'c' is the only answer choice less than 180>153

another way to solve this would be to focus solely

on answer choice 'c'-

so 85% of the school is female and 85% as a fraction is 0.85, and we need to find the total amount of girls that attend said school and the only way to do that is to multiply-

0.85*180=153>180

good luck :)

Sub y in the second equation by y in the first equation:
We get 4x+3(-3x+3)=-1
4x-9x+9=-1
-5x=-10
x=2
Sub in the first equation
y=-3(2)+3
y=-3

Answer:

x=2 and y=-3

Step-by-step explanation:

y=-3x+3, 4x+3y=-1 solve using substitution

y=-3x+3 solve y=-3x+3 for y

4x+3y=-1

4x+3(-3x+3)=-1 simplify both sides of the equation

-5x+9=-1

-5x+9-9=-1+-9 add -9 to both sides

-5x=-10

-5x/5=-10/-5 divide both sides by -5

x=2

substitute 2 for x in y=-3x+3

y=(-3)(2)+3

y=-3 simplify both sides of the equation

I'm so sorry if this isn't right

Answer:

C. 50 (.20) + 20

Step-by-step explanation:

50 is the numbers of cookies so in order to find the total cost of JUST cookies we multiply 50 by .2 which is each cookies cost.

Then we add an additional 20 for the box.

So we get 50 (.2) + 20.

*BONUS* The total cost for one box is $30

45 minutes because if it takes 1/5 of a page in 3 mins.

1/5 = 3 mins
2/5 = 6 mins
3/5 = 9 mins
4/5 = 12 mins
5/5 = 15 mins

So 3 pages would be 15 x 3 which is 45
