The answer to 31,096 + 59,721 is 89,817 so B 89,800 is the best estimate
2nd- The answer to 69,896 - 42,901 is 26,995 so A 26,900 is the best answer
3rd- 630,429 - 27,811 is 602,618 so the best answer(s) would be A 630,400 and C 27,800
Answer:
Step-by-step explanation:
Algebraic expressions tend to have atleast one unknown variable in it. In order to solve the expression we need to assign a fixed value to that variable or isolate it if the expression is equal to another value. For example, in the following expression we have the variable x, if we give it a value of 5 we simply solve like a regular expression...
5x + 3
5(5) + 3
25 + 3
28
Therefore, if we swap the variable x for the value of 5 we would get a value of 28 in this algebraic expression.
Answer:
y + 2 = 
(x - 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 4 = (x - 3) ← is in point- slope form
with slope m =
Parallel lines have equal slopes, thus equation of parallel line
with m = and (a, b) = Q(1, - 2) is
y - (- 2) = (x - 1) , that is
y + 2 = (x - 1)
Answer:
143 because if you subtract 49 and 28 you get 21 the you divide 21 and 1623
