For the answer to the question above asking how many solutions does the system of equations have? y - 6x = -3 and 4y - 24x = -16. The answer is y - 6x = -3 -6x + y = -3 6x - y = 3
4y - 24x = -16 -24x + 4y = -16 24x - 4y = 16 reduces to 6x - y = 4
and this has no solutions
Answer: First option
12 candy bars were sold
Step-by-step explanation:
Call x the amount of candy sold and call z the amount of cookies sold. Then we know that

We also know that candy bars sell for $ 3 and cookies sell for $ 5. The profit was $ 76
So:

To find the quantity of candy bars sold we must solve the system of equations:

Multiply the first equation by -5 and add it to the second equation

Answer:
Step-by-step explanation:
The measure of angle a is twice the measure of angle b. This means that
a = 2b
The measure of angle c is at least one degree more than the measure of angle a. This means that
c ≥ a + 1
c ≥ 2b + 1
if the sum of the three angles is at least 61 degrees, it means that
a + b + c = 61 - - - - - - - - - - - - - 1
Substituting a = 2b and c = 2b + 1 into equation 1, it becomes
2b + b + 2b + 1 = 61
5b = 61 - 1 = 60
b = 60/5 = 12
c ≥ 2× 12 + 1
c ≥ 25
25 ≥ a + 1
25 - 1 ≥ a
24 ≥ a
a ≤ 24
Therefore, the range possible measurements for angle b is
b ≤ 12
