Answer:
160.07
Step-by-step explanation:
Answer:
y≤-1/3 (fraction)
And on the number line it will start from -1/3 (-0.333) and go less than -1/3 ( to the left, and it will be shaded
Step-by-step explanation:
First we expand the brackets, making it -15y+12≥17
Then we move 12 to the other side, making it negative, -15y≥17-12
Simplify, -15y≥5
Then we divide on both sides to isolate y, flipping the greater than sign to less than because when you divide or multiply by a negative number, the sign flips. y≤5/-15
Then we simplify by dividing the fraction by 5, making it -1/3. y≤-1/3
If you have any doubts, inform me
If it’s a triangle I’m going to assume it’s 70 degrees
For this, you would use simultaneous equations.
w=walnuts
a=almonds
3w+6a=51
5w+4a=55
Find a way to make one of the unknowns equal. since we are trying to work out the price of a pound of walnuts, I am going to make a equal on each side to leave us with w. This leaves us with:
15w+12a=165
6w+12a=102
Then take them away to leave w:
9w=163
Then solve:
w=163/9
= 18.11111111...
Then round it to 2 decimal places as the measurement is currency.
So 1 pound of walnuts equals $18.11
