<h2>the original number is 38</h2>
Step-by-step explanation:
Let the two-digit number be 10t+u where t is the tens digit and u the units digit.
-------------------
EQUATION:
t+u = 11
10u+t = 10t+u + 45
-------------
Rearrange the equations:
t+u = 11
9t-9u = -45
-------------
Simplify:
t+u = 11
t-u = -5
---------
Add the equations to solve for "t":
2t = 6
t = 3
--------
Substitute to solve for "u":
3+u = 11
u = 8
Answer:
the answer would be v ≥ $5.80
Step-by-step explanation:
he doesn't need exactly 5.80 a day so that marks out A and C and since he needs v to be at least 5.80 it means B would be the answer
Just divide 8 nad 9 to get X
Answer:
To earn profit : 50 < c < 150 is the expression that best expresses this situation.
Step-by-step explanation:
The minimum number of cattle Mr. Riley can raise = 50
The maximum number of cattle Mr. Riley can raise = 150
Let the number of cattle is represented as c.
So, according to the question:
To make profit,
Number of cattle > 50
and Number of cattle < 150
or, c > 50
and c < 150
Hence, on combining both the expressions, we get
To earn profit 50 < c < 150 is the expression that best expresses this situation.
