Answer:
42
Step-by-step explanation:
4+6 = 10
10+7 = 17
17+2 = 19
19+9 = 28
28+2 = 30
30+9 = 39
39+3 = 42
Answer:
Step-by-step explanation:
collect terms
11x+61=180
move numbers to one side and x to other
11x=180-61
11x=119
x=119/11=10.8
Answer:
(2/3, 13/3) (Exactly one solution)
Step-by-step explanation:
Write these equations in a column:
x+y=5
2x-y=-3
Note that we can eliminate y immediately by adding these two equations together. We get:
3x = 2, so that x = 2/3.
Substituting 2/3 for x in the first equation, we get:
2/3 + y = 5. Clear out fractions by multiplying all three terms by 3:
2 + 3y = 15, or 3y = 13. Then y = 13/3, and the solution is
(2/3, 13/3) There is exactly one solution.
Answer:
This property states that if quantity a equals quantity b, then b equals a. Another property that can be explained by this is the transitive property of equality. It tells us that if a quantity a equals quantity b, and b equals the quantity, c, then a and c are equal as well.
It’s D because if he withdrawals u would minus
