Answer:
After simplifying we get (x,y) as (1,3).
Step-by-step explanation:
Given:
,

We need to use elimination method to solve the and simplify the equations.
Solution;
Let
⇒ equation 1
Also Let
⇒ equation 2
Now by solving the equation we get;
first we will Add equation 2 from equation 1 we get;

Now Dividing both side by 5 using division property of equality we get;

Now Substituting the vale of x in equation 1 we get;

subtracting both side by 1 using subtraction property of equality we get;

Now Dividing both side by 7 using division property of equality we get;

Hence we can say that, After simplifying we get (x,y) as (1,3).
Answer:
84 blocks.
Step-by-step explanation:
If you are adding 2 to each day (which already has 4) in a 2 week period (14 days) than you would have to time 2(14) and 4(14) and add them. Thus would make the answer 84 blocks.
30 M&Ms
1) Gathering the data
12-ounce bag of trail mix = 18 M&Ms
20-ounce bag=?
2) Assuming that the M&Ms are placed in following a constant rate we can write the following proportion:
12 --------------- 18
20 --------------- y
<em>Cross multiplying it due to the first property of proportions</em>
<em />
12y =20 x 18
12y = 360
y=30
3) So, I'd expect to find 30 M&Ms at a 20-ounce bag of trail mix.
