Answer:
<em>Tadeo Volunteered for 12 hours while Dylan volunteered for 2 hours</em>
Step-by-step explanation:
Let the total number of hours Tadeo volunteered be x
Let the total number of hours Dylan volunteered be y
If together they volunteer at a total of 14 hours, then;
x + y = 14 ...... 1
If<em> </em>Tadeo Volunteered at the library six times as many hours over the weekend as Dylan, then;
x = 6y
Substitute x = 6y into 1;
6y + y = 14
7y = 14
y = 14/7
y = 2
Since x = 6y
x = 6(2)
x = 12
<em>Hence Tadeo Volunteered for 12 hours while Dylan volunteered for 2 hours</em>

Step-by-step explanation:
Constance's car has a 12-gallon gas tank.
She can travel 25 miles on one gallon of gas, so she can travel
miles using all gas from the tank.
Constance begins with a full tank of gas and drives at a constant rate of 40 miles per hour.
So, Constance can drive for
hours.
Answer:
x = 3 and y = 2
Step-by-step explanation:
For the triangles to be congruent.
The hypotenuse and a leg of one triangle and the hypotenuse and a corresponding leg of the other triangle must be congruent, that is
x = y + 1 → (1) congruent legs
3y = x + 3 → (2) congruent hypotenuse
Substitute x = y + 1 into (2)
3y = y + 1 + 3, that is
3y = y + 4 ( subtract y from both sides )
2y = 4 ( divide both sides by 2 )
y = 2
Substitute y = 2 into (1)
x = 2 + 1 = 3
