Answer:
x²+ x = 0
x ( x +1 ) = 0
x = -1
x³-25x=0
x ( x² - 25 ) = 0
x² = 25
x = 5
x²=4x
x² - 4x = 0
x ( x- 4 ) = 0
x = 4
4x²-4x=1
4x²-4x - 1 = 0
4 x² - 2x - 2x - 1 = 0
2x ( 2x - 1 ) - 1 ( 2x- 1 ) = 0
2x- 1 ) ² = 0
2x = 1
x = 1/ 2

-32.065 as a mixed number in lowest terms is
<u>Solution:</u>
A mixed number is a combination of a whole number and a fraction.
Need to represent -32.065 into mixed number in lowest form means need to represent -32.065 in mixed number and fraction part of the number must not have any common factors other than one between numerator and denominator
=> -32.065
Separate the decimal part, we get
= - (32 + 0.065)
Express the decimal as fraction value,
Reduce to lowest terms,
Hence -32.065 as a mixed number in lowest terms is
Answer:
The equation that can be used to determine m, the number of minutes it will take the helicopter to reach the hospital is .
Step-by-step explanation:
We are given that a medical rescue helicopter is flying at an average speed of 172 miles per hour toward its base hospital. At 2:42 p.m., the helicopter is 80 miles from the hospital.
As we know that the Distance-Speed-Time formula is given by;
Here, Distance = 80 miles
Speed = 172 miles per hour
Time = m (the number of minutes)
Firstly, as we can see that the speed is in miles per hour but the time is in minutes, so we will convert the time in hours, i,e;
Time =
So,
m = 27.91 ≈ 28 minutes.
Hence, it will take 28 minutes for the helicopter to reach the hospital.

Answer: Ray will make 17 and 1/2 cups of sauce.
Step-by-step explanation: I figured this out because if it makes 3 1/2 cups normally then you just multiply it by 5. 3 x 5 is 15, and 1/2 x 5 = 2 1/2. Lastly 15 + 2 1/2 = 17 1/2.
Hope this helps.
