It's simple .....
just subtract R and C.....
so 50x+10-10x-275
= 40x-265
so the answer is B
Scientific notation is always between 1-10 times 10 to the power of how many decimal points it needs to be moved over
So the first number would be 9.25*10^-4. You can figure out the power by just moving the decimal over and count until the number is between 1 and 10
Answer:
13M+27
Step-by-step explanation:
Answer:
y =36
z= 54
Step-by-step explanation:
The angles 3y and 2y form a straight line, so they add to 180 degrees.
3y+2y =180
5y = 180
Divide each side by 5
5y/5= 180/5
y =36
The angles z, y, from a 90 degree angle
z+y =90
z+36 = 90
Subtract 36 from each side
z+36-36 = 90-36
z = 54
