Answer:
18. 20,000.
19. 0
7. 1
11. 101
Step-by-step explanation:
18. I think is stays the same, because an integer is a number that is not a fraction. So still 20,000.
19. Sea level is at zero altitude. So answer is 0.
7. |17-16| = |1| = 1. The lines around it are called absolute value signs and mean to make the answer positive.
11. |-101| = 101. As said before the lines mean to make the inside part positive.
Answer:
Step-by-step explanation:
Total Students in Class = 25+ 15=40
Probability= (Number of Girls in Class) ÷ (Total students in Class)
Probability of girl= 15 ÷ 40 = 0.375
The first one is congruent by ASA. The second does not have to be congruent, we don’t know enough.

The ordered pair is a solution of x - y = 2 and 3y - x = 8 is (x, y) = (7, 5)
<h3><u>Solution:</u></h3>
Given two equations are:
x - y = 2 and 3y - x = 8
<em><u>To find: orderes pair i.e (x, y)</u></em>
Let us consider:
x - y = 2 ------- eqn 1
3y - x = 8 --------- eqn 2
<em><u>Let us solve eqn 1 and eqn 2 to find values of "x" and "y"</u></em>
On rearranging eqn 2, we get
-x + 3y = 8 ------ eqn 3
Add eqn 1 and eqn 3
x - y = 2
-x + 3y = 8
(+) ---------------
0 + 2y = 10
2y = 10
<h3>y = 5</h3>
Therefore from eqn 1,
x - y = 2
x - 5 = 2
x = 5 + 2 = 7
<h3>x = 7</h3>
Thus the ordered pair to the given equations are (x, y) = (7, 5)
