(6x+9y=78) - (6x+4y=38) = (5y=40) = y=8
(2x+3(8)=26) = (2x+24=26) = (2x=2) = x=2
Answer:
D
Step-by-step explanation:
x^2+2x-5-(-3x^2-4x+1)
x^2+2x-5+3x^2+4x-1
4x^2+6x-6
1=5-4 because you have to substitute x and y (x,y) or (5,1)
The time Natasha listens to the radio can be represented as 7 times five sixths, 35/6 or 5/6 + 5/6 + 5/6 + 5/6 + 5/6.
<h3>How to find out the time Natasha listens to the radio in one week?</h3>
- Time per day: 5/6 of an hour
- Time per week: 5/6 + 5/6 + 5/6 + 5/6 + 5/6 = 35/6
or 5/6 x 7 = 35/6
<h3>How to represent this?</h3>
There are three options:
- 5/6 + 5/6 + 5/6 + 5/6 + 5/6
- 35/6
