Answer:

Step-by-step explanation:

the measure of the angle= 47-27=20

since it is a square all sides are equal

A=a*a=36

length=width=6

perimeter 2L+2W=12+12=24

Answer:

See step-by-step explanation

Step-by-step explanation:

16. C, <AOB = 20

The total angle (<AOC) is equal to the sum of the angles inside of it (<AOB and < BOC).

<AOC= <AOB + <BOC

47=<AOB+27

<AOB=20

17. 24

Area of a square = $s^{2}$

36= $s^{2}$

s= 6

One side is 6

The perimeter of a square is 4(s)

4(6) = 24

Word of encouragement:

Good luck!

If 11250 = m(600) + b and 7650 = m(400) + b, how do I find the values of b and m? I forgot how to compare when I have two differ

Answer:

$b=450$ and $m=18$

Step-by-step explanation:

This exercise is an example of linear system equations. A system of linear equations is a set of (linear) equations that have more than one unknown. The unknowns appear in several of the equations, but not necessarily in all of them. What these equations do is relate the unknowns to each other.

The easy way to solve this problem is by using the reduction method.The reduction method consists of operating between the equations, such as adding or subtracting both equations, so that one of the unknowns disappears. Thus, we obtain an equation with a single unknown.

Ordering the equations as a system equations.

$\left \{ {{600m+b=11250} \atop {400m+b=7650}} \right.$
