x => Hamburgers
y => Hot dogs
x + y = 26
3.5x + 2y = 70
-2x - 2y = -52
3.5x + 2y = 70
-----------------------
1.5x = 18
x = 18 / 1.5 = 12
y = 26 - 12 = 14
They sold 12 hamburgers and 14 hot dogs
Answer:
- 5.9%
Step-by-step explanation:
Data provided in the question :
Future value of the amount invested = $4,600
Principle i.e amount of purchase = $7,500
Time, n = 8 years
Now,
let the interest rate be 'i'
using compounding
$4,600 = $7,500 × (1 + i)⁸
or
0.613 = (1 + i)⁸
or
1 + i = 0.941
or
i = -0.059
or
interest rate = - 5.9%
Here negative sign means loss
First, let's convert 0.77 to a fraction.

Multiply by 100

Now make the denominators the same, to make it easier to find which fraction is greater. We can do this by finding the LCM of the denominators, then however many times the denominator goes into that number, we multiply the numerator by the same amount.
For example, the LCM of 100 and 6, is 300. 6 goes into 300 50 times, so the numerator for 4/6 is 200 (4 x 50 = 200). :)

The answer is 0.77 is greater than 4/6. :)

Answer:
no
Step-by-step explanation:
if u subtract negative nine from one side of the equation, in order to keep both sides of the equation equal, you must subtract 9 from the other side. moreover, if you subtract nine from one side and add 9 to the other, there will be a 9+9=18 difference in values of both sides
