Answer:
25, 50, and 105.
Step-by-step explanation:
Let the first angle be A, the second angle be B, and the third angle be C.
First, the sum of the three angles in a triangle is 180. Thus:
We know that the measure of A is twice the measure of B. Thus:
And the measure of C is 80 more than the measure of B. So:
Let's substitute A and C into the original equation:
Now, let's solve for the second angle (B). Combine like terms:
Subtract 80 from both sides:
Divide both sides by 4:
So, the second angle is 25 degrees.
This means that the first angle is 2(25) or 50 degrees.
And the third angle is 80+25 or 105 degrees.
And we're done!
The angles are 25, 50, and 105.
Answer : The cost of one hot hot dog and the cost of one hamburger is, $3.75
Step-by-step explanation :
Let the cost of hot dog be, 'x' and hamburger be, 'y'.
Given:
5 hot dogs and 2 hamburgers cost is, $12.00. The equation will be :
..............(1)
2 hot dogs and 5 hamburgers cost is, $14.25. The equation will be :
..............(2)
Now we have to determine the value of 'x' and 'y' by using substitution method.
............(3)
Now put equation 3 in 2, we get:
y = 2.25
Now put the value of 'y' in 3, we get:
x = 1.5
Cost of hot dog = x = $1.5
Cost of hamburger = y = $2.25
Now we have to calculate the cost of one hot hot dog and the cost of one hamburger.
Cost of 1 hot hot dog and 1 hamburger = x + y
Cost of 1 hot hot dog and 1 hamburger = $1.5 + $2.25
Cost of 1 hot hot dog and 1 hamburger = $3.75
Therefore, the cost of one hot hot dog and the cost of one hamburger is, $3.75
