Answer: Jordan
Step-by-step explanation:
You will need to subtract 3x from 5x, then since there is a minus sign in front of the 7 it will count as a -7, so u add 7 cross it out and then add 7 to the -4(which is also negative cause it has a minus sign in front) and then you have ur answer
5x-3x=2x
7+ -4= 3
Answer: 2x-3
Answer:
Step-by-step explanation:
The shaded region is the difference of areas of semicircle AB and triangle ABC.
ABC is right triangle as AB is diameter, so C is right angle.
<u>Area of semicircle:</u>
- A = 1/2πr² = 1/2*3.14*4² = 25.12 cm²
<u>Area of triangle:</u>
- A = 1/2BC*AC = 1/2*4*
= 2
= 13.86 cm²
<u>Shaded are is:</u>
- 25.12 - 13.86 = 11.26 cm²
In this case, the starting amount is 525 pounds. You want to convert it into kilograms so you need to know the equal amount of pounds into one kilogram. The equal amount is: 1kilogram/ 2.2 pounds.
To convert it you simply need to multiply the starting amount with the equal amount, then the calculation is:
525 pounds x 1 kilogram/2.2pound= 525 kilogram / 2.2= 238.63 kilograms.
Then the end amount is 238.63 kilograms
