The Answer is 2/3
Steps: 1/4(1-(2/3^2+1/3)
Answer:
14/16
Step-by-step explanation:
If you multiply 8 by 2 you get 16 so multiply 7 by 2 and you get 14/16
Answer:
The system of equations has a one unique solution
Step-by-step explanation:
To quickly determine the number of solutions of a linear system of equations, we need to express each of the equations in slope-intercept form, so we can compare their slopes, and decide:
1) if they intersect at a unique point (when the slopes are different) thus giving a one solution, or
2) if the slopes have the exact same value giving parallel lines (with no intersections, and the y-intercept is different so there is no solution), or
3) if there is an infinite number of solutions (both lines are exactly the same, that is same slope and same y-intercept)
So we write them in slope -intercept form:
First equation:

second equation:

So we see that their slopes are different (for the first one slope = -6, and for the second one slope= -3/2) and then the lines must intercept in a one unique point. Therefore the system of equations has a one unique solution.
Let the price of 1 litre of milk be x$
Let the price of 1 loaf of bread be y$
According to the problem
333x + 555y =11
444x+444y=10
On subtracting the two,
We get
(333x+555y=11) * 444
(444x+444y= 10) * 333
(-) (-) (-)
147852x + 246420y =4884
147852x + 147852y = 3330
(-) (-) (-)
------------------------------
98568y = 1554
y = 1554/98568
= 0.0157$
=0.02$
Price of 1 loaf of bread= 2 cents
On putting the value of y
333x + 555*0.0157 = 11333x + 8.7135 = 11333x = 2.2865x = 2.2865/333x = 0.00068$ = 0.01$
Price of 1 litre of milk = 1 cent

Easy tip: just multiply seven and four together!
7•4=28
So both seven and four fit into 28
