This is a true equation because 9 + 7 is equal to 16 which is also equal to 7 + 9
Answer:
780
Step-by-step explanation:
17 is the divisor, while 2635 is the dividend. So that,
= 155
The quotient = 155 = 1 hundreds, 5 tens and 5 units
Also,
2635 - 1700 = 935
Hence, let the unknown value be represented by x. Then;
935 - x
The answer of the subtraction should be equal to the quotient of the division.
935 - x = 155
935 - 155 = x
780 = x
Therefore the unknown value represented by a box is 780.
Answer:
- D. r = 4; center is (2, 0)
Step-by-step explanation:
<u>Equation of a circle:</u>
- (x - h)² + (y - k)² = r², where (h, k) is the center and r is the radius
<u>Given equation:</u>
<u>Rewrite as:</u>
The center is (2, 0)
The radius is r = 4
Correct choice is D
Answer:
part a: -40 < x < 140
part b: open circles on both -40 and 140 with an arrow from each pointing inward. (towards zero). the solutions represent temperatures that will keep the gas in liquid form.
part c: it will freeze because -49 is less than -40, and therefore not a solution to the inequality.
explanation
a. x must be greater than -40 and less than 140 as outlined in the problem. so x > -40 and x < 140
b. open circles are non inclusive, and we do not include -40 or 140 because the gas will not be a liquid at those temps.
