Answer:
300 because if he traveled 150 in 3 to find six just multiply by 2
Answer:
The rate at which the distance between the cars increasing two hours later=52mi/h
Step-by-step explanation:
Let
Speed of one car, x'=48 mi/h
Speed of other car, y'=20 mi/h
We have to find the rate at which the distance between the cars increasing two hours later.
After 2 hours,
Distance traveled by one car

Using the formula

Distance traveled by other car

Let z be the distance between two cars after 2 hours later

Substitute the values

z=104 mi
Now,

Differentiate w.r.t t


Substitute the values



Hence, the rate at which the distance between the cars increasing two hours later=52mi/h
Answer:
3
Step-by-step explanation:
92x0.2=18.4
18.4 is between 15 and 20
Answer:
1. 8x - 13
2. 19r - 19s
3. 8m - 10
4. 36(4t - 1)
5. 4(2x - 3)
Step-by-step explanation:
For the first three it’s pretty basic, just follow PEMDAS
for the last two, just find the largest number that divides into both of them and take it out
Answer:
y = 15
y = -10
Step-by-step explanation:
y=-5x
y= -5(-3)
= 5 × 3 = 15
y = 15
y = -5x
y = -5(2)
y = -5 × 2
y = - (5 × 2)
5 × 2 = 10
y = -10
