Answer:
4 cm on map
Step-by-step explanation:
since 1 cm on map represents 20 km on road, we can either use proportion or ratio to solve this, I'm using direct proportion
map : road
1 : 20
x : 80
20x = 80
x = 80/20
x =4
so 80 km on road is 4 cm on map
please give brainliest
8 plus 3 is 11, 15 minus 11 is 4
To write the equation, you can start with the answer of $680. She receives $400 + $20*plans sold:
400 + 20p = 680
20p = 280
p = 14
{$400 + $20 * 14 = 680}
Sam sold 14 plans to make a total of $680.
Answer:
8x +4y
Step-by-step explanation:
6x + 3y + 2x + y
1) add similar variables together.
2) 6x + 2x = 8x
3y + (1)y = 4y.
3) y by itself basically means 1y, since in front of every variable theres an invisible 1.

Step-by-step explanation:
In this problem I'm assuming the office is rectangular.
so
The area of rectangle is equal to

where
L is the length of the rectangle
W is the width of the rectangle
In this problem we have

so
------> equation A
Find two possible dimensions of the office
case A) Assume a length side L and find the value of W in the equation A
so
For 
substitute in the equation and solve for W


The dimensions are
