Hi,
Let's simplify this equation step-by-step.
7−2(5−2x)−10x+25−4x−3
Distribute:
=7+(−2)(5)+(−2)(−2x)+−10x+25+−4x+−3
=7+−10+4x+−10x+25+−4x+−3
Combine Like Terms:
=7+−10+4x+−10x+25+−4x+−3
=(4x+−10x+−4x)+(7+−10+25+−3)
=−10x+19
Answer:
=−10x+19
Have a great day!
Answer:
12 miles
Step-by-step explanation:
sorry if im wrong
The unit rate is 60 miles per hour and the driver will reach before time with the calculated constant speed
Step-by-step explanation:
Given
Distance = d = 45 miles
Time = t = 3/4 hour
The unit rate is defined as the distance per unit time. In this case, the unit rate can also be called speed.
So,

Using this unit rate we can see if the car can travel 65 miles in 1.25 hours or not
Given
Distance = d1 = 65 miles
Speed = s = 60 miles per hour
Putting the values in the formula for speed

As we can see that 1.08 is less than 1.25 so the driver will reach the meeting before time if he drives on a constant speed of 60 miles per hour
Hence,
The unit rate is 60 miles per hour and the driver will reach before time with the calculated constant speed

Answer:
f(5) = 3200
Step-by-step explanation:
Using the recursive formula to generate the terms, that is
f(2) = 2 × f(1) = 2 × 200 = 400
f(3) = 2 × f(2) = 2 × 400 = 800
f(4) = 2 × f(3) = 2 × 800 = 1600
f(5) = 2 × f(4) = 2 × 1600 = 3200

Cross-multiplying and rearranging, we get:

or written without using latex:
k^2 = h^2 - 3mq
