Answer: 
Step-by-step explanation:
Subtract 490 from both sides
Then flip
multiply both sides by
to cancel out 
Thus giving you -735 as your
.
Then you plug it back into the equation to solve.
Answer:
a. 0.43*125=
53.75
b. this is a little harder we need to find what the conversane is for ec to us
ec 0.43= 1 tt so
6.3*0.43
2.71 ec=1 us
850.94 divided by 2.71
314 us

In a right angled triangle we can use Pythagoras theorem to determine third side in case two sides are given.
The formula of Pythagoras theorem is given by:

Where x , y and z are sides of triangle , z is hypotenuse.
Now we use this formula to find hypotenuse.
Plugging other two sides which are 5 in. and 12 in.



Taking square root on both sides
square root of 169 is 13
so we have z=13
Hypotenuse is 13 inches.
ANSWER: 25
EXPLANATION: First find the area of one single square by multiplying b(BASE) * h(HEIGHT). Repeat for other figure. Finally you will add both sums.
