To make a triangle 2 of the sides must be the same length
In this problem it just goes left to right, 1-18+25 = -17+25 = 8
(1-18)+25-17+25=8<span>
</span>When you do addition and subtraction they are reversible so you just go left to right
Answer:
5
Step-by-step explanation:
The denominator must be the same, so just think of the LEAST COMMON MULTIPLE, The LCM here is 8, because you can multiply 4 by 2 to get 8.
so when you multiply, you multiply both on the top and on the bottom, so this would be:
3 x 2 / 4 x 2 = 6 / 8
Now you can add or subtract: 6/8 - 1/8 = 5/8
Answer:
Employee's pay before rise was $19.25.
Step-by-step explanation:
It is given in the question that an employee earns $20.79 per hour after receiving 8% rise and we have to calculate employee's hourly pay before rise.
So to solve this let's assume employee's hourly pay before rise was $a
Then after raise the salary will be = $a + 8% of $a
= a + (a×
Now a+(.08)a = 20.79
⇒ 1.08a = 20.79
⇒ a = 20.79÷1.08
⇒ a = $19.25
So employee's hourly pay before rise was $19.25.
