The value of n would be 2.2 if that's what you wanted.
Let the number of hamburgers = h
Let the number of cheeseburgers = c
Now we translate the given information into equations.
"combined total of 770 [ham]burgers and cheeseburgers"
h + c = 770
<span>"there were 70 more cheeseburger sold than hamburgers"
</span><span>
</span><span>c = h + 70
</span><span>
</span><span>
</span><span>Our system of equations is
</span><span>
</span><span>
</span><span />h + c = 770
c = h + 70
The second equation is already solved for c, so we replace c of the first equation with h + 70.
h + h + 70 = 770
2h + 70 = 770
2h = 700
h = 350
Answer: 350 hamburgers were sold on Monday.
<span>Let the wall's length be y. So the fence parallel is also y.
We form the equation;
2x + y = 240
Now the area A is x*y, which is given as 5500.
We have 2 equations with 2 variables. Solve them and get the answer.
xy = 5500
2x + y = 240
Y = 5500/x
2x + (5500/x) = 240
2x^2 - 240x + 5500 = 0
x^2 - 120x + 2750 = 0
Work out the value(s) of x from above. </span>
We can multiply 336 by 2/3 to find out.
2/3(336)
To make this easier, we can change 336 to 336/1, which does not change it's value.
Multiply 336 by 2.
336 * 2 = 672
Multiply 1 by 3.
1 * 3 = 3
Our new value is 672/3
Evaluate, divide both sides of the fraction by 3.
672/3 = 224.
3/3 = 1
224/1
224/1 = 224
