Answer:
y=3
Step-by-step explanation:
Answer:
number = 9
Step-by-step explanation:
number = x
3 is added to a number = (x+3) result
3 times the number = 3x
15 less than three times the number = 3x-15
the results is 15 less than three times the number
x+3 = 3x -15
3x-x= 3+15
2x = 18
x=9
Answer:
Step-by-step explanation:
We have:
(1) two trapezoids with bases b₁ = 7cm and b₂ = 5cm and the height h = 4cm
(2) three rectangles 3 cm × 7 cm, 3 cm × 4 cm and 3 cm × 5 cm.
The formula of an area of a trapezoid:
Substitute:
Calculate the areas of the rectangles:
The Surface Area:
Considering the graph of the velocity of the car, it is found that the interval in which it was stopped at a traffic light was:
Between 3 and 4 minutes.
<h3>When is a car stopped at a traffic light?</h3>
When a car is stopped at a traffic light, the car is not moving, that is, it's velocity is of zero.
In this problem, the graph gives the <u>velocity as a function of time</u>, and it is at zero between 3 and 4 minutes, hence the interval in which it was stopped at a traffic light was:
Between 3 and 4 minutes.

Answer:
x=59
Step-by-step explanation:
x+12+x+x-9=180
3x+3=180
-3 -3
3x=177/3
x=59
