Answer:
Step-by-step explanation:
Givens
B = 10
h = 12
Formula
Area = 1/2 * B * h
Solution
Substitute into the formula
Area = 1/2 * 10 * 12
Area = 60
Answer:
ana spends 2 hours 50 minutes working
Step-by-step explanation:
ana starts working at 2:40 pm and finishes work at 5:30 pm.
Let's bear in mind that there is 60 minutes in one hour.
Ana started 2.40 , the :40 means 40 minutes
While I 5:30, the :30 means 30minutes
The amount of time spent by anna at the working place.
5:30-2:40= 4 hours minus 2 hours, 90 minutes- 40 minutes
= 2 hours 50minutes
ana spend 2 hours 50 minutes working
Shirts = 3 x $24.50 = <span>$73.50
$125 - $73.50 = $51.50
so
$51.50 / $14.50 = 3.55

7x + 4 = x - 2 -- (1)
To rewrite the equation above as a system, we simply let (1) be equal to y, i.e.
7x + 4 = x - 2 = y -- (2)
Recall from the rule of transitivity: If a = b = c, then this implies that a = c & b = c. From this, we have (2) to be expressed as
y = 7x + 4 -- (i)
y = x - 2 -- (ii)
Note: (i) & (ii) are both regarded as a system of linear equation which can be evaluated simultaneously.
