21^2/0.219 = 2013.69863
2 significant figures are the 20, so the answer is 2000
50 + (50 * 0.065) = the answer, sorry I don't have my calculator on me.
3/4 and 3/8 have to have equal denominators, so multiply 3/4 by 2/2 because it's equal to one, so it doesn't change the value of the fraction, but it makes the denominator (the number on the bottom) bigger.
3/4 x 2/2 = 6/8
Now subtract.
6/8 - 3/8 = 3/8
Don't subtract the denominators.
3/8 can't be simplified.
Answer:
C.
Step-by-step explanation:
It was an estimated answer, therefore C. is correct because even if he did do the full calculation he would get 5211, which is still less than 6000.
Also, brainliest, please??
The equation of a line that passes through (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given
y-(-4)=-5(x-3)
the point is (3,-4)
