Answer:
Explanation:
Distance and time are directly related, meaning that distance / time = constant.
In this case the constant is the rate or speed.
Thus you can write:
And, given that covering 30 miles requires 25 minutes, to calculate the time needed to cover 25 miles, you can set this proportion:
- 30 miles / 25 min = 25 miles / t
To clear t you do cross multiplication:
- t × 30 miles = 25 miles × 25 min
Divide both sides by 30 miles:
- t = 25 miles × 25 min / 30 miles = 20.8 min ≈ 21 min ← answer
You would find the solution of this question by finding what plus 4 times its self is 50.clay has 40 red apples because he has 10 green 10*4=40 and 10+40=50.

Answer:
The intersection point of the given lines is (1,1).
Step-by-step explanation:
Here, the given equations are:
y = - 2 x + 3
y = x
Substitute y = x in the first equation,
y = -2 x + 3 becomes y = -2 (y) + 3
or, y + 2 y = 3
or, 3 y = 3 ⇒ y = 3/3 = 1
⇒ y = 1
Now, as x = y ⇒ x = 1
Hence, the intersection points of the given lines is (1,1).
