Answer:
B
Step-by-step explanation:
Let x = every day he rented the kayak
Since the store charges $60 for each day, multiply x by 60 like this: 60x
They also have $25 on top of that; 60x + 25
This all has to equal $325; 60x + 25 = 325
To solve for x, subtract 25 from both sides
60x + 25 = 325
- 25 - 25
60x = 300
Divide both sides by 60
60x/60 = 300/60
x = 5
This means Tobias rented the kayak for 5 days
Answer:
x = 70°
Step-by-step explanation:
x = one of the congruent angles in the triangle
Given angle measure: 40°
x = ? + ? = 180 - 40 = 140
x = 70
First substitute .5x in for y to get a solvable equation. You should get 6x+8(.5x)=30. Then multiply 8 times .5 to get 6x+4x=30. Then combine like terms (6x+4x) to get 10x=30 and divide both sides by 10 to get x=3. Then plug this x value (3) into the other equation (y=.5x) to find the value of y. Y=.5(3) so y=1.5. Therefore the answer is B.
